Author's note: Wow, I am sorry for making you guys wait so long. My only excuse is that I've had graduation parties, thunderstorms constantly, and I've been...busy? That's a bad excuse, but it's the truth. I edited the lemon in this chapter because I don't want fanfiction DOT net getting on my case about how it "goes against the rules". So I did tone it down as much as I could without leaving out too much. This is the final chapter, by the way. I don't have a sequel planned, so it's safe to say that there will not be one. It's great to see how many people love Siegfried.

Kaiba was very fun to write in this chapter. He likes to tease poor Sieg a lot, hehe. I do have 2 pictures related to this story at my art gallery at darkfire75 DOT deviantart DOT com.ANYWAY, I hope you enjoyed this story as much as I did writing it. The ending kind of bothers me for some reason, even though it sounds really sweet. It feels like it's missing something. Oh well. If you guys like it, that's all I care about. Enjoy!

All Roses Have Their Thorns

Chapter 5

Isana had never imagined that Siegfried would come all the way to Japan just to get her to go back to Germany. She was furious with him. Demanding for her to return with him and leave Kaiba Corp when she had a steady job was stupid and selfish. He didn't own her. He hated her. So seeing him angry with her boss was the icing on the cake. She sat in between them at her desk: Kaiba standing with his arms crossed over his chest and a superior smirk on his face while Siegfried was yelling off profanities and demanding Kaiba make her quit before he did something drastic.

"You're making a fool out of yourself," Kaiba sneered. "As usual."

Siegfried's face was red with anger, but the fire in his eyes would not diminish. "I came here to bring her back vith me!" he said, pointing to the blonde. "I vill not leave!"

"Miss Hainsworth, do you have any wish to return to Schroeder Corporation?"

Isana stared at Siegfried, who sent her a mix between a pleading look and an accusing look. Kaiba waited patiently for her response. "No, Herr Kaiba. I have no vish to return to Schroeder Corp."

"Well, I think that settles things," Kaiba said turning back to his office.

"Vait!" Siegfried cried. "Please! May I talk vith her? If she von't come back, at least let me speak to her."

"Miss Hainsworth, is that all right with you?"

"I suppose." The brunette left them alone. "All right, Siegfried. You have five minutes. Speak," she growled in German.

"Leon misses you," he began. "I came on his behalf."

"That's a lie. I write to him almost everyday, telling him what I'm doing. You just want me to work for you again so that you can order me around. That's not happening anytime soon, Siegfried."

"So you'd rather work for Seto Kaiba? He's a worse employer than I am."

"On the contrary. I get paid well and he's quite decent when you don't get on his bad side."

Siegfried's eyes narrowed. "So that's it? You refuse to come with me?"

"It appears that way."

The pink-haired man tensed up and turned to leave. He looked over his shoulder at her before disappearing down the hall. Isana leaned back in her chair and sighed. Kaiba stepped out of his office. "He's gone?" he mumbled.

"Yes, sir," she replied.

"Good. He was starting to annoy me." He narrowed his eyes suddenly. "He was extremely persistent. Makes me wonder what his true objective was."

"He probably just vanted me back vith him so zat he could control me bezzah."

Kaiba frowned. "You believe that?"

" But I can't zink of any ozzer reason."

It had been foolish of Siegfried to think that barging into Kaiba Corp would have Isana begging to come home with him. He would never admit it, but he missed her presence. She had been away from Germany for a good few months and in that time, he had felt himself severely wishing she was playing with Leon somewhere so that he could join them. But that wasn't the case now. They were both adults at 22 years of age and Leon was 18. Over imaginative fantasies should not be what occupied Siegfried's mind.

Maybe he had been too straightforward. He had never been particularly good with persuading people, finding it too close to begging. But in all honesty, if he had had his own way, he would have taken Isana by force. Kaiba had taken away someone very important to him. It angered him to no end. Now he had no place to stay for the night, since he had expected bringing Isana back wouldn't take that long.

"Not your day, is it?" called a voice from his left. He turned and scowled. It was Kaiba. What did he want now? To humiliate him further? "Barging into my company was amusing. Trying to force Miss Hainsworth into returning to Germany with you was even funnier. But seeing you look so dejected out on this park bench...well...I'm almost ashamed to say I'm quite enjoying myself."

"Glad to see somevon is having a good laugh at my expense," Siegfried replied darkly. "Vat did you come here for, Kaiba?"

The brunette sighed and sat beside him. "As much as I hate you, it's almost pitifully sad how you're taking this rejection. All she said was that she wasn't going back to Schroeder Corp."

"You haven't known her as long as I have."

"No. But I wouldn't throw a hissy fit if she decided to quit Kaiba Corp."

Siegfried glared him. "I am not having a hissy fit."

"You're being a drama queen then. Look, if this one incident is going to cause you to go into a depression, you might as well just hand your company over to someone more capable of running it."

"Vhy in ze seven hells are you concerned about me, Kaiba? I am your arch rival."

"Trust me, I haven't forgotten. But if you could see your face. It's really pathetic."

Humiliating him was one thing, but insulting him was a no-no. The pink-haired man sprung to his feet and glared at Kaiba. "I suppose you know vat I'm zinking now, right? You seem to know everyzing! So tell me, Herr Kaiba, vat is it zat I am zinking right now?"

Kaiba smirked. "You like her."

"Excuse me!" Siegfried shrieked, his face turning as pink as his hair. "How could you even suggest zat I—"

"That you like her? Simple. I may not have much experience in the romance field, but it's pretty obvious when the guy is displaying his feelings openly."

"I am not!"

"Then explain why your face is turning red."

Siegfried pouted. "Isana is my brozzer's friend. Zat is all."

"Is it? Or do you wish you and her had something more?"

"I cannot believe I am having zis conversation vith you, of all people."

Kaiba grinned as he crossed his legs. "It's pretty safe to say you do like her. You're a man. It was bound to happen."

"Zank you for pointing out ze obvious." Siegfried stared at his shoes for a while before answering. "I'm not sure ven I started liking her. Maybe a year or so ago. But she has alvays been near me. Und ven she left to vork here, I vos angry."

"Afraid I'd take her away from you?"

"Perhaps. You can have anyzing you vant. Und you hate me, so I figured you vould try und take her."

"Please. I'm not that low. Anyway, so the basic story is that you like her but you're too afraid to tell her?"

"I am not afraid," Sieg growled.

Kaiba rolled his eyes. "Fine. Keep yourself in denial. On a side note, I know where her hotel is here. I could...give you directions."

"For vat price?"

"That I never see you again."

"Hmm...zat vorks for me."

"Stupid jerk," Isana growled as she climbed into the shower. He came all the way here just to force me to come back to work for him! Ugh! After lathering herself up and washing her hair repeatedly, she stepped out of the shower and wrapped a towel around herself. She walked out of the bathroom and nearly had a heart attack when she saw who was sitting on her bed. "Siegfried!" she cried. "What the hell?"

"Hallo," he greeted. His aqua green eyes widened in shock at seeing her in a towel. "Um..."

"What are you doing here?" she hissed.

"I wanted to talk with you."

"We already talked. Now leave!" He slowly stood up from the bed and walked over to her. She backed away into her dresser, glaring hatefully at him. "I'm warning you, I'm gonna do something I won't regret!"

"Please hear me out," he said softly. He took one of her hands in his and placed his lips on her palm. Isana watched as his tongue darted out and swirled around her palm as if massaging it. The simple action had her wishing she didn't know this crazy pink-haired man. He had such an affect on her and she didn't know why. He let her hand go and pressed his body against her. All that separated him from her was a towel. Isana gulped. "I haven't been honest with you, Isana. When you left Germany, I was very angry but sad as well. I missed you, much more than I will even admit. Herr Kaiba, he has helped me see what I've been denying myself for years." He stepped even closer, making sure to press his lower half against her. "You mean a lot to me, Isana."

The blonde held her breath. She could feel his muscles tensing under that ridiculous suit he was wearing. How she wanted to rid him off the horrible thing and trace her hands down his slim chest. Wait, where had THAT thought come from? One of Siegfried's hands came up to caress her cheek. He brought their faces a few inches apart.

"I think I love you. But I'm not sure. Would you let me find out?"

If Isana had been any other girl, she would have dropped the towel, spread her legs, and said 'take me now.' However, she was not another girl and knew just who this man was and what games he could be playing. She narrowed her eyes, but that did not dull the obvious lust-filled gaze he now looked at her with. "How can I trust you, Siegfried?" she spat.

His answer was his lips devouring hers. Isana held onto the back of the dresser at the intensity of the kiss. Siegfried pulled her against him, delving his tongue inside her mouth. Isana hesitantly brought her hands up to touch his hair, which was surprisingly silky soft, despite how it looked. He moaned and deepened the kiss. Halfway through, she started to kiss back, her mouth working wonders against his. He grinned and carefully guided her away from the dresser and towards the bed. They broke their kiss and stared into each other's eyes before kissing with such ferocity that it looked painful.

Siegfried's hands were on her shoulders, trying to pull the towel off of her. Isana broke the kiss with a smile and blushing furiously, untied the towel and let it drop to the floor. Isana's arms instantly went up to cover her chest. But Siegfried pulled them away and just stared at her, memorizing as much of her body as he could. "You're beautiful," he whispered before kissing her neck. She gasped and nearly melted in his arms at the way his tongue tickled her collarbone. He traveled to the valley of her breasts and began to slowly massage them with his palms. Isana groaned and threw her head back. Siegfried saw how pert her nipples had become and eagerly swooped down to capture one in his mouth. Her swirled his tongue around and around, enjoying the sounds she was making. Her hands were wildly reaching for his hair and pulling him down so that he had nearly a whole breast in his mouth. He suckled greedily and smiled when he saw how flushed her face was.

The fact that he was still dressed while she was naked was beginning to irritate her. She tried to unbutton his suit, but because it was so complicated, she became angry while he merely chuckled. He backed away from her and slowly started to peel off his clothes. Isana watched hungrily. When he had stepped out of his pants, she hadn't expected to see such a beautiful man before her. If she had been an artist, she would have sculpted him on the spot. Siegfried reached his arms out to her and she eagerly embraced him. Their bodies meshed together. Without hesitation, Sieg kissed her passionately, running his hands up and down her backside. Isana broke the kiss and started to suck at the junction between his neck and collarbone.

Siegfried laid her on the bed, covering her body with his own. He used his hand to spread apart her thighs, enjoying the look of excitement on her face. Her arms pulled him down on top of her and he found himself being kissed repeatedly. It ended much too quickly for him, but he couldn't wait any longer. He had to take her now. Her legs spread to their fullest as he readied himself at her entrance. Isana's hands clutched his shoulders. "I trust you," she whispered, seeing the worry in his eyes. His hair was sticking to his face from all the sweating he had done. He smiled, kissed her gently, and then thrust his hips forward. There was no stopping her scream. Isana held onto him tightly as tears sprang from her eyes.

"I'm sorry," he muttered as he pushed inside again, this time breaking her virgin wall. His pace started to quicken. Their love making continued long into the night. "I love you," he panted suddenly.

"I love you too," she replied, gasping for breath. Tired at last, Siegfried laid himself beside her on the bed and curled up under the covers. He wrapped his arms around her and kissed her. He stared into her blue eyes for a long time as he smiled warmly at her.

"I would have preferred making love in Germany, but I couldn't wait," he admitted.

"Neither could I." She snuggled against his chest. "Thank you, Sieg."

"For what?"

"Everything. I have a reason to return to Germany with you now."

His eyes widened. "You're coming back with me?"

"Of course. I can't stay here and let you go back alone."

Siegfried was too happy to say anything more. He hugged her tightly and kissed her forehead. Thank you, Isana. I love you more than you could ever know. And thank you, Kaiba. If not for your advice, I would be a sad excuse for a man right now.

Isana awoke the next morning feeling unbelievably happy and content. Siegfried's arms were still holding her. By his gentle breathing, she knew he was still asleep. Brushing a hand into his bangs, she placed a kiss on his forehead before sitting up in the bed. She yawned and stretched and checked the digital clock on the nightstand. Her eyes widened.

"Oh no!" she cried. "I'll be late for work!" She literally flung herself from the bed and into the bathroom to shower quickly.

Siegfried yawned and blinked his eyes as he woke up. "Something wrong?" he mumbled.

Isana had just run out of the bathroom, throwing on her clothes for work. "I'm gonna be late!" she whined.

"I don't think Kaiba will care, in all honesty."

"Are you crazy, Siegfried! He's my boss! I'm his secretary! If I don't show up, who's going to take all his calls!"

"Perhaps he could find a substitute?"

She glared at him. "Not funny." She finished buttoning her blouse and was about to hurry out the door, but he called her back.

"Aren't you forgetting something?" he said with a grin.

"Oh! Right!" Siegfried's expectant face that she would kiss him goodbye fell as he saw her grab a piece of bread off the kitchen table and shove it in her mouth. "Can't go to work on an empty stomach."

"Isanaaaaaaaa!" he whined with a pout.

She sneered at him. "Serves you right for making me late."

"But it was your fault as well!"

She waved to him and left the apartment, leaving Siegfried alone and feeling utterly useless. He angrily got out of the bed and went to take a shower. He wasn't letting her get away from him that easily. He picked up the phone and searched through the phone book until he found the number for Kaiba Corp. He waited patiently until he heard someone pick up.

"Hallo, zis is Isana Hainsvorth of Kaiba Corp. Do you vish to schedule an appointment vith Herr Kaiba?"

Smiling, Siegfried replied, "Not particularly, no. However, I vould very much like to make an appointment vith you, love."

There was a long pause. Then, "GET OFF THE LINE, SIEGFRIED!" He winced as she slammed the phone down hard on the other end.

"She's frightening when she's angry," he muttered.

Seto Kaiba had been having a pretty decent morning, all things considered. Isana had been slightly late coming into work, but he had a pretty good idea why and wasn't going to punish her. All his paperwork was done and he could finally relax a bit. Suddenly, there was a knock on his door and he sighed. "Come in."

A teenager with black hair tied back in a low ponytail stepped in, his gray eyes screwed up with concern. "Hey, Seto. I'm sorry to bother you but...I think something's wrong with your secretary."

"What do you mean, Mokuba?"

"Well...just look at her." Kaiba stood up from his office chair and went to the door to see what the fuss was about. He was shocked to see Isana glaring at the phone as if trying to burn a hole in it.

"Miss Hainsworth," he said clearing his throat. She continued to glare at the phone. "Miss Hainsworth!" He sighed heavily. "ISANA!"

The German girl jumped in her chair and found herself face to face with her boss and his younger brother. "O-Oh, hallo, Herr Kaiba, Mokuba. I-I'm sorry. It's just...somevon keeps calling und it isn't for you, sir."

"Let me guess. He's got pink hair and bad fashion sense."

She nodded. "Afraid so."

"Next time he calls, patch him through to me. I'd like to have a word with him, Miss Hainsworth."

She grinned. "It vould be my pleasure, sir."

Sure enough, the phone rang as predicted. Isana made sure Kaiba was in his office before patching it through. Kaiba sat down in his chair and picked up the phone, without bothering with a greeting.

"Love, are you ready to make zat appointment now?"

Kaiba nearly gagged at how sappy the pink-haired German had become overnight. "As flattered as I am by your enthusiasm, Siegfried, I'll have to decline your offer," he growled.

There was a moment's pause. "Zat vosn't funny, Kaiba."

"Really? I thought it was."

"Vhere is Isana?"

"At her desk...doing work. I don't appreciate you keeping my secretary from doing her job properly, Siegfried."

"Is it vrong of me to call my girlfriend to make plans?"

"It is when it in interferes with her job."

"Fine. I von't bozzer her."

"Good. Now, there's something I'd like to talk to you about."


"I'm going to fire Isana after today."

"Vat? Vhy? She loves vorking for you!"

"Ahem, let me finish. There's no doubt she's been one of the best secretaries I've ever had, but it's obvious she isn't happy to be here. I can tell she'd much rather be spending time with you."

"Und since ven have you been concerned about people ozzer zan yourself, Kaiba?"

"People change over time, for better or worse."

"I find zat hard to believe, but vhatever you say. So you are saying you vant Isana to come back to Germany vith me?"

"Yeah. Would you like a private jet to take you back tomorrow?"

"I can call for my own jet, zank you."

"Suit yourself."

There was another long pause. "So...can I hang up now?"

"Do what you wish." Without waiting for another answer, Kaiba hung up and laced his fingers together. He had to admit, he would miss Isana but she could always be replaced anyway. He just couldn't imagine anyone else filling her spot. When it was time for her to go home, he quickly dialed in her desk number and waited for her to pick up. "Miss Hainsworth, this is Kaiba. I'm calling to request that you take a long vacation. In fact, don't bother showing up here ever again. You're fired."

He waited until his words reached her. She was a smart girl...she would figure out his true meaning. Suddenly, very softly, he heard her mumble, "Zank you, Herr Kaiba." The line went dead and Kaiba leaned back in his chair, satisfied that he had done the right thing. Goodbye, Isana. And you're welcome.

Isana would miss working at Kaiba Corp, but now that she was with Siegfried, she couldn't stand to be apart from him anymore. They had years to catch up on and she didn't want to waste that precious time. When she returned to the hotel, she found Siegfried waiting for her. "It's all right. You don't have to tell me. I know," he said. "Kaiba's too good to us."

"Which is funny, since I recall him being one of your most hated people when we were in our teens."

Siegfried grinned. "We're going back to Germany tomorrow. I already called Leon and he'll be sending us a private Schroeder jet to take us home."

"You're unbelievable, Sieg," she murmured as she hugged him. "That's why I love you so much."

Unable to mask his excitement, he pulled her into the apartment and closed the door. "Since it's our last night in Japan...I thought we could...celebrate."

Isana's blue eyes widened. ""

"Of course, if you'd rather wait, that's all right."

Having sex again so soon sounded promising, but Isana was already tired enough and wasn't sure if she'd be able to last more than an hour. She shook her head. "I'm sorry, but not tonight. I'm very tired."

"That's fine. I still get to sleep with you, so I'm not bothered," he chuckled.

"Very funny, Siegfried."

Returning to Germany wasn't easy. Isana had been away for two months. But she was happy that she was returning with Siegfried and not by herself. Leon greeted them at the airport, obviously astounded that the two weren't fighting. "Wow, I didn't think you'd get her to come home so quickly," he murmured.

"I didn't have to force her," Siegfried said smiling. "She wanted to come back."

"Something happened between you two..."

Isana and Siegfried exchanged a look. "It's called love, little brother," Sieg answered.

"You mean you guys...?"

"Yep," Isana chuckled. "Took us forever, but everything's all right now."

Leon gaped at them. "I just can't believe it. Fours years of hating each other's guts and suddenly, in just two days, you've fallen in love?"

"Life is mysterious."

"Life is weird," Leon corrected. "So now I'm gonna have to stomach you two eating each other's faces every couple minutes?"

"We don't eat each other's faces," Isana frowned.

He raised his eyebrows. "Yeah...sure. C'mon, let's go. The limo's waiting outside for us."

Siegfried and Isana lagged behind. "I wanted to give you something, but not with every staring," he mumbled. He reached into his coat pocket and pulled out a red rose. "I know I'm a little late for Valentine's Day...and your birthday...but...well..."

Isana's blue eyes widened. "It's beautiful. Thank you so much, Siegfried." She kissed his cheek and ran towards the limo. Smiling, Siegfried touched his cheek and followed her. His life had just gotten much better and he was pretty sure that Isana would be init for a long time. He noticed a jeweler's shop as they drove back to the Schroeder castle and his smile widened. He had one last proposal to make and prayed that Isana would accept and make him one of the happiest men alive.
