A/N: I do not own YGO. Only the plot and her OC characters for this story. Flames will not be tolerated. Kaiba learns about unconditional friendship, unknowingly taught by Mokuba AND Yugi. Wasn't enough room for the full summary. Half of this is sibling fluff though!

March 30/05>This story is due for revision SOON! Good grief, I can't believe I wrote this. Some of it is so...odd! I'm narrowing it down to the three main OC's: the mother, Jeff, and the little sister. This fic seriously needs a re-write...

Sixteen year old Jeff Turner entered his home. He shared it only with his mother in the lowest part of Domino City. They were considered poor to most. His mother scrounged up enough money to send him to school. She worked day and night, always appearing haggard and weary. Always wanting the best for her son and young daughter. Jeff was part of a street gang in that poor part of the city. He was the leader. He had chestnut brown hair and clear blue eyes, close to aqua. Trouble was his middle name. Trouble as in one who likes to cause trouble for the fun of it. Of course, that would all change very soon. It began the day Mokuba Kaiba decided to walk home and explore along the way...

'I hope Seto doesn't find out about this...' Mokuba thought worriedly as he walked through busy Downtown Domino. He had called the chauffeur and told him he would be walking home. Just for once he wanted to be on his own, to explore the city without getting dirty looks because of his brother's reputation of a hard businessman.

He gazed at the neon signs, the large billboards, and the unique gift shops and chic clothing stores. Hundreds of people milled about, heading to and from work, shopping, or just eating out.

It was right after school for Mokuba so that would explain the fact that other kids and teens were walking around.

Mokuba approached and alley and decided to go down there. Why? He did not know himself. Something inside of him prompted him to do so. He was at that age where he wanted adventure and to be on his own. Eventually he would learn that he should not try and grow up so fast.

He reached the end of the alley and was torn between going left or right. "Maybe I should just go right." Mokuba said out loud. "It's closer to going home...I think." He continued along, the daylight starting to grow dim within the alley. "Does this ever end?" He wondered aloud and came to a street. He was far from Central Domino. "This is weird..." He walked so more. 'I don't think I'm going in the right direction. Oh why did I ever think I could handle things on my own!' He thought miserably. "Hey! I still have my cell!" Mokuba reached into the shirt of his school uniform. There was a small pocket with a small cell phone tucked inside. "Time to phone Seto." He hoped Seto wasn't too mad.

"What do you think you're doing?" A cold voice broke his thoughts. Mokuba's heart beat fast as he looked up seeing the tall sixteen- year-old, Jeff, and two of his buddies behind him. One had blonde hair slicked back, the other, jet black hair with a silver streak.

Mokuba's bottom lip quivered as he backed up. He dropped the phone and quickly tried to grab it but Jeff was quicker.

"What's this?" Jeff looked at the phone, noting the speed dial of Kaiba's office and home office. "Well, you're the younger brother of that rich kid, Kaiba, aren't you?" Apparently Jeff went to the same school. "Aren't you?"

"Yes." Mokuba gulped. "And he'll come for me! He always does!"

"That may be." Jeff murmured, staring at Mokuba. Despite the fear in his eyes, Jeff could clearly see the resemblance of Seto Kaiba, the teen CEO. "But you didn't call him." The two gang members behind him snickered. "I don't think he'll be there for you this time."

Meanwhile, Kaiba was in his limo. An uneasy feeling came over him and he took out his own cell and called the mansion. He ordered the maid to find Denson, the man who usually picked up Mokuba at Domino Elementary School. "Is Mokuba at the mansion?" Kaiba asked.

"Why...no sir. He called me and told me to stay here. He said he was going to walk home."

Kaiba sighed and shouted at the man and then hung up. He opened his laptop and activated the scanner to find the small microchip Kaiba had installed in Mokuba's phone. It found the younger Kaiba's cell right away. "What is he doing over in the dumps?" Kaiba muttered to himself and instructed his limo driver to head for Western Domino.

"Let me go!" Mokuba struggled against the two thugs that held him while Jeff clutched Mokuba's cell phone in his hand. "You're...going...to be...sorry!" He croaked out. 'Seto...' He thought numbly as he realized they held him good. He was unable to move. 'Please come soon, Seto...'

"Release my little brother...now." A familiar icy voice demanded. Kaiba stood there his fists clenched, having changed into his navy trench coat and dark shirt and pants. His intense blue eyes flashed at the three teens.

The two teens, Billy the black-haired one, and Pete, the blonde, loosened their grip on Mokuba slightly but did not let go completely.

"Seto!" Mokuba sighed in relief but he knew his older brother would be angry with him for making a foolish decision.

"And what if I don't want to?" Jeff sneered, his aqua eyes like a storm on the sea.

"You'll have to deal with me then." Kaiba shot back, stepping forward.

"Bring it on." Jeff stepped forward as well. He swung at Kaiba and got him in the chin. Kaiba retaliated, getting him in the stomach. Jeff fell to his knees and rolled out of the way. He jumped to his feet and shoved Kaiba into the wall. The fight continued on until Jeff ordered his pals to let go of Mokuba, who ran to his brother's side. Jeff had a black eye and a bleeding lip. Kaiba had a bruise on his cheekbone and a cut on the other cheek. He sent a death glare in Jeff's direction as he allowed himself to be hugged by Mokuba.

He said nothing and turned to go back to his limo. Jeff, in his own way, had surrendered, knowing Kaiba would win. Kaiba always had the upper hand. "That's it, go, go back to your mansion, your money." Jeff spat. "You know nothing of being poor." Jeff muttered, scowling.

His words echoed in Kaiba's mind as the two brothers made their way back to the mansion. Mokuba looked up at his brother. Normally the silences between them were comfortable but not this one. It was the most unnerving silence Mokuba had ever experienced. "Seto...? I'm sorry, I really am. I promise I won't do it again."

"You had better not." Kaiba sighed. "I don't want to lose you."

Mokuba glared at his brother. "Why do you let me off so easily?"

Kaiba looked at Mokuba, his eyes softening. "You should know. You're the one who taught me." Kaiba climbed out of the limo, leaving Mokuba sitting inside, eyes wide.

'How did I teach him?' Mokuba wondered as he followed Seto.

It was almost midnight and Kaiba could not sleep. He tossed and turned until he sat up in bed, rubbing his temples, running his hand through his hair. 'You know nothing of being poor...Seto...why do you let me off so easily?' Mokuba and Jeff's voices ran through his mind.

Kaiba knew the reason to the latter. He always let Mokuba off so easily because Mokuba had shown him in his own special way, unconditional love. Mokuba saw all the things Seto did, heard all the mean things he said to people. Yet, Mokuba still loved him no matter what. That was what truly touched Kaiba's heart.

Jeff, on the other hand, was a different matter. True, Kaiba did not know what poor was, in terms of money and wealth. But he did know what poor was in matters of emotions. Kaiba had been through so much in his childhood and teen years. He did not choose to be poor. That was what had been planned for him. At least Kaiba was not like other rich tycoons. He earned his wealth, usually the hard way. It didn't come to him. He went to it, earning it on his own, driven by his desire for Mokuba to have the best of everything.

Nobody affected Seto Kaiba except Mokuba and occasionally Yugi Muto. His lighter side that is. Jeff Turner was just another human on the sidelines, jealous of his prosperity. Or was he?

The next day at school, rumors were going around. Jeff came to school grudgingly, not happy with wearing the official school uniform. His black eye was visible to the students but the cut on his lip healed quickly. Flanked by Pete and Billy who also went to Domino High, he walked down the halls to his class, glaring at anyone who dared to look at him.

Kaiba entered the school after him and his appearance only fueled the rumors more. Jeff had shown up at school, looking like he had been beaten up. Then Kaiba showed up with a bruise and a cut.

"Man, I've never seen Kaiba looking so beat up!" Joey exclaimed seeing the CEO enter the class and take his usual seat. Jeff and his friends were sophomores.

Yugi got out of his seat and walked over to Kaiba. "Hey Kaiba...what happened to you?" He still always tried to be Kaiba's friend. Yugi was another example of unconditional love, only it was unconditional friendship.

"It is of no concern to you, Yugi." Kaiba glowered at him and stared straight ahead, hoping Yugi would go away.

Yugi sighed and went back to his friends. "He won't tell me."

"So what's new?" Tristan shook his head. "Why do still try to be his friend, Yugi?"

"Yeah," Joey chimed in. "He always brings ya down."

Tea looked over at Kaiba sadly. She had begun to understand what Yugi meant. It was always the same answer.

"Because," Yugi looked at his friends. "I know we've only seen the surface of Seto Kaiba."

Kaiba got home and changed into his work clothes. He typed away at his computer and read contracts, bills, and papers. It was always the same. The same three people lingered on his mind. 'Why can't they leave me alone!' His mind screamed. He exhaled and leaned back against his chair.

"Big brother?" Mokuba appeared at the doorway. "Are you alright?"

Kaiba smiled faintly at his brother. "I am." He answered gently.

"Are you sure?" Mokuba knew something was wrong. Ever since yesterday's events, Kaiba had been unusually quiet. He walked over to Kaiba. "Something's wrong. I know it!"

"No, Mokuba, nothing's wrong..." He shook his head. 'I can't lie to him.' "Mokuba, why do put up with me?"

Mokuba's eyebrows knitted. "What kind of a question is that?"

"Just answer me."

Mokuba shrugged. "You're my big brother, the only family I've got. You always took care of me. You mean the whole world to me." Mokuba said quietly.

Kaiba smiled. "Come here." He opened his arms and the two brothers hugged. "Mokuba, you don't know how much of an impact you've had on my life."

"Seriously, what gives?" Mokuba asked curiously. "You seem different."

Kaiba stared outside for a long time. He did not answer Mokuba's question. "I need to go visit someone."

"Be careful!" Mokuba told him as they walked down the stairs.

"I will. I'll see you tonight." Kaiba shut the door and headed over to his limo. "Take me to...Western Domino..." He knew Western Domino was notorious for being the poorest and saddest section of Domino City.

Jeff dropped his backpack onto the dirty couch of their small living room. His mother was at her second job and a neighbor was watching his kid sister, Lila, who was only 7 years old.

Someone knocked on the door and he went to open it. It was the neighbor returning Lila. Jeff took care of her in the evenings. "Hey, Lila, did you have a good day?" He asked softly, smiling.

"Look what I did!" She held up a drawing.

"Awesome. Are you hungry?" Jeff grinned at her enthusiastic nod. She never asked anymore about his physical small injuries. They walked into the small kitchen. Lila had the same chestnut colored hair only it was long and she had pale blue-green eyes. She looked so much like her older brother.

The doorbell rang. 'Strange...no one uses the doorbell.' Jeff thought. "Stay here." He walked back to the front door and opened it. His mouth dropped and it quickly turned into a snarl. It was Kaiba. "What are you doing here?"

To be honest, Kaiba didn't know either. What was he doing there anyway? "I...I don't know." Kaiba responded absentmindedly.

Jeff raised his eyebrows. "Well if you don't know, I guess I don't need to keep the door open..." Jeff started to shut it good when...

"No! I mean, I know why I'm here." Kaiba protested, frowning. "I want to know something."

"What?" Jeff asked coolly.

"First, why did you have to harass Mokuba?" Kaiba questioned, a glare forming in his eyes.

Jeff was taken aback. "Uh, I don't know...I always harass people."

"Why?"

Before Jeff could answer, Lila appeared behind him. She stared at Kaiba with huge eyes. "Who's that?" She tugged on the back of Jeff's old long sleeve.

Jeff scowled at Kaiba. "Look, I just do, alright?" He shut the door.

'He has a little sister...' Kaiba thought dumbly. He was still standing at the doorstep. He hit the doorbell again.

The door swung open. "Look, Kaiba, why don't you-"

"Jeff?" A soft female voice was heard. Kaiba spun around and standing there was a pale woman. "Jeff, what's going on?" She didn't seem to notice Kaiba. All she wanted to do was sleep.

"Mom!" Jeff exclaimed. "I, uh..."

"Is this a friend?" She finally noticed him and offered a small smile. "Well don't be so rude, Jeff, invite him in!" She never really seemed to care what people thought of them or their home.

Kaiba was about to say he wasn't staying long but Jeff hastily opened the door wider. "Come on in, friend." Jeff emphasized, shooting him a glare. Kaiba returned the glare and stepped in. Jeff's cheeks reddened slightly as Kaiba glanced at the living room for he was embarrassed of his home's appearance. It wasn't too bad compared to others around the neighborhood but still...this was Seto Kaiba of Kaiba Corp. Surely he was used to seeing much better places. He was rich after all...

Since his mother was home, Jeff would have to be nice towards Kaiba. He never wanted to upset his mother. Mrs. Turner spoke again. "It's a little messy but I haven't had much time to clean lately." She indicated the small living room. A small TV was visible in the corner and toys were on the floor.

Kaiba nodded, still polite to certain adults. It was part of being a businessman. Mrs. Turner didn't seem to realize whom she was speaking to. She was a kind, gentle woman, merely trying to survive in the world so that her two children could have a better life.

Just like Kaiba. Nobody saw the inside of him, what he was really like. He was only doing what he thought was best for Mokuba.

"I'll leave you two alone." Mrs. Turner headed for her room. Lila ran over to the TV and turned it on, just in time for an evening show for kids.

Jeff looked over at Kaiba. "You can leave now."

Kaiba nodded. "I will." He let himself out and headed for the limo. He didn't know how bad things could be. He didn't have that kind of problem. 'What's wrong with me? I don't care about other people's circumstances.' He thought angrily.

'But your parents did...and Mokuba too.' Another voice seemed to creep into his mind.

Kaiba's shoulders slumped against the soft cushioning of the limo. That was true. He may be a Kaiba now and CEO of a large corporation but he was still his birth parent's son and he had a bit of both of them in him. His father's determination and his mother's kindness which was deep inside of his heart and he rarely allowed it to show. Only to Mokuba, who seemed to be a reflection of his mother. Kaiba was more of a reflection of his father but not in personality. His stepfather was the cause of that.

The limo stopped and the door was opened for him. He got out and headed for the front door of the Kaiba Mansion. Suddenly his home and business didn't seem so important anymore. Right now, all he wanted to see was Mokuba.

Mokuba was slowly falling asleep on the couch. He always seemed to do that, forgetting about his bedtime. Kaiba sighed, smiling and picked him and up and carried him to his room. He set Mokuba gently onto the bed and tucked him in. "Goodnight little brother..." He whispered softly and left the room.

That night, Kaiba dreamt. His mother appeared in his dream, smiling at him. "Seto!" She called softly.

Kaiba found himself in a strange place. They were surrounded by mist. He opened his mouth to say something but nothing came out.

"Seto!" She cried again. "My dear son...don't be ruined by pride..." She looked at him sternly but her eyes were still loving. She then smiled and faded away. "I love you."

"No...don't go." Kaiba felt a lump in his throat. "Please."

Everything became black and Kaiba fell asleep.

The next morning, Kaiba awoke earlier than usual for school. He did his usual routine. Shower, eat, and read and calculate at the same time. But this morning was different. He was still thinking about the dream he had had. 'Don't be ruined by pride...' echoed in his head. What did she mean by that?

"Morning, Seto!" Mokuba bounded down the stairs and entered the large kitchen.

"Morning, Mokuba." Kaiba continued to read the newspaper.

"I had a dream last night...about dad." Mokuba said, pouring himself a glass of orange juice to keep his energy up.

"Our stepfather?" Kaiba asked incredulously. 'No-Mokuba wouldn't have a dream about our stepfather and call him "dad"...'

"No, our real dad!" Mokuba grinned at him. "He told me how proud he was of me."

'Is he proud of me?' Kaiba wondered about both his father and brother.

"...and then he said always stick by your brother no matter what." Mokuba smiled happily. "And I always will."

Kaiba smiled at him. "You're a good kid, Mokuba."

A/N: How do you like it so far? This is NOT a yaoi by the way. I don't write those kinds of stories. Review please, much appreciated.
