Okay, so first of all ~ YES, this IS mpreg; YES, Ace will get Luffy pregnant :'V (just to make sure…) YES, Luffy will get pregnant! And I'm stating this so many times bc I just want to make sure that people won't come here criticizing the fic bc it's mpreg -.-'' feel free to criticize bc it's a bad fic or I'm a bad writer, whatever; but don't criticize its genre pls.

Anyways… Yô -0-)/ ~ I'm finally writing something with drama about these 2 *yay* xD , don't worry I'll insert some comedy every now and then ;3 and I still can't believe that my first long multi-chapter AceLu fic is mpreg o3o but I really had to, this world needs AceLu babies u/v/u ❤
Moving on… the important stuff about the fic that you must know is:
1- I'll update a chapter per month because I want to have chapters ahead of the ones I'm posting, thus I need to update slowly. For now I have a chapter and half written and I want to have at least 2 or so...
2- my native language isn't English, thus you'll always find ugly mistakes in my fics, I apologize for that u.u
3- I think (I'm sure tbh) that my stories are very predictable, yet I'll try to keep the mystery until it's needed xD but I still think that people can figure out the whole stuff very easily hahaha
4 (and last, for now xD)- the characters will be ooc every now and then, but don't worry I'll make sure to warn before that happens !

And because this is getting too long, I won't bother you with my notes anymore x3 ~

Prologue

"Then I'm leaving now!" The dark haired boy announced cheerfully, running down the long way of the holy hill.

"Ah wait Luffy…!" A beautiful lady with long dark hair called at the boy, but she knew that there was no way that she would be able to stop him; nobody would, surely.

"I'll see you all tomorrow. Bye, Robin!" The excited boy waved at her with a wide smile across his features without realizing her panic. Luffy ran the rest of the way down the hill without worries or hesitation; at the moment, like every single Sunday, he was the happiest angel in heaven.

On the other hand, the beautiful woman didn't give up; she exited the luxurious mansion where they had been, and tried to stop the cheerful creature with her words and slow run. "Wait Luffy… You mustn't go!" She kept running, her hands grasping the silky tissue of her long white dress for better mobility. Through her mouth the same words kept escaping desperately trying to stop the cheerful angel, yet it was too late. Nothing could be done anymore and she knew it, but she wanted to believe that she would be able to protect that angel with her life like he had done long ago. If only she could fly, she would spread her beautiful wings and catch up with the boy... unfortunately flying was forbidden in the holy land.

Luffy looked all around the garden for the one he most wished to see, yet there was no one there. The anxiety inside him grew incredibly. He always waited impatiently a whole week, though he always tried to distract himself, for the next Sunday so he would be able to see the person he liked the most in the entire world. Yet the wait he had to endure each time was unbearable.

"He's late, geez!" The angel pouted and fell softly on the green grass, lying down over it with both his arms under his head, serving as a pillow. "Well, since he's not here yet, I'm going to take a nap." Luffy decided, more to remain calm than anything else. He just wanted to see the other male so bad that he barely controlled his feelings.

The dark winged male flied down in order to land on the grass right next to the sleeping boy who wascomfortablysnoring. His dark wings disappeared on his back magically, as a gentle smile formed its way on his lips. He sat down, next to the younger boy and softly took his hand to the angel's warm cheek, caressing it gently, his thumb running the way over Luffy's scar tenderly, while his eyes were focused on the boy's innocent face. However his smile vanished as his orbs observed Luffy's mouth. A sudden but expected pang of guilt attacked his heart. He knew it was wrong; he knew that he couldn't love the angel at all, yet he couldn't help it. Even if he was a demon and Luffy an angel, Ace still loved him in the same way; perhaps more. His feelings towards Luffy just kept growing and growing and growing, to the point of overflowing uncontrollably every time he was with the angel. He honestly didn't know what to do anymore. The more he thought of resisting, the more his heart would tell him to succumb to his strong feeling of love. Should he really do it? Sometimes he pondered about it.

Ace's thumb traveled across the sleeping angel's face, stopping at the soft sensation of Luffy's lips.

What could happen if he succumbed, anyways?

His finger ran the warm bottom lip as the will of giving in to temptation was getting stronger and more uncontrollable by the second. The dark winged male leaned his face very softly and slowly to Luffy's, their mouths were getting closer and closer in each passing second. There was no way back. It was too late; he knew it. His lips were practically brushing against the angel's, so he would never be able to resist at this point.

He continued lowering his mouth to the angel's, and was finally able to plant a sweet kiss over his lips; yet when he thought that everything would be that easy and alright, he had yet to be proven wrong.

"What are you doing, Ace?"

Said demon froze at the familiar tone of that voice. It seemed like time had stopped when the gentle yet mad timbre of that voice reached his ears. His moment of craziness was over; Ace had regained his consciousness. The guilt he felt so far up until now was no longer comparable to the strong; intense and very uncomfortable feeling of guilt eating at him for all his sins at the moment.

"So…? Aren't you going to reply? The cat ate your tongue?"

Ace looked up in the direction of the voice's owner, and wasn't the least surprised when he saw the angry and hurt expression in the blond male's face who was stopped a few feet away from him and the sleeping angel.

"Ace, answer me! What are you doing?"

The demon looked down, at Luffy's tranquil face, gritting his teeth and pondering about a way to reply without hurting his friend even more. Yet the only way to do that was lying and he would never lie to him.

"Why are you asking me that if you already know the answer, Sabo?" Ace said bitterly, facing the other man with a fake smile in his lips.

Unable to hold back his anger, the blond ran to the demon, pulling him up by grabbing the dark shirt he wore. The demon avoided eye contact by looking down. "Ace you bastard, are you aware of what you're doing?" Sabo yelled furiously due to his friend's careless actions. He knew, very well in fact, about Ace's feelings towards Luffy since ever; he found them extremely obvious in truth, yet nobody else seemed to have noticed them. To make things worse, Luffy seemed to feel exactly in the same way towards Ace, which increased their sins all the more; hopefully the demon didn't seem to be aware of such feelings and that relieved Sabo a little. However, it was precisely because Sabo knew of such forbidden feelings that he felt the need to prevent his important friends from losing control. Sabo knew how Ace and Luffy liked to act impulsively…

"…"

The blond looked at him lightly surprised for hearing the demon's voice, yet because it had left the dark haired male's mouth in the form of a whisper, Sabo frowned intrigued.

"What?" He asked.

Ace faced the blond, finally, looking as angry and hurt as Sabo. "Do you really think that I'm not aware?!" He yelled grabbing Sabo by the collar of his white shirt roughly. "Do you think this is not hard for me?"

"Ace…" The blond muttered softly, releasing the demon's shirt. Sabo was unsure of how to react in truth; he was too taken aback with the other male's outburst.

"It's so fucking hard that I can barely look at him without wanting more than a simple friendship!" The demon panted, breathing heavily as he tried to get calmer. He let go of Sabo's clothes and stepped back distancing himself from the other man.

"Ace I-" The blond tried yet in vain since he was interrupted right away by Ace.

"I know that you're right. I'm aware that this is wrong, but I can't help it. I love him so much... and it's because of that that I'm going to leave."

"What…"

"It's like you heard. I'm leaving so I can organize my mind and feelings. That's why Sabo, take care of him in my place okay?"

"What the hell are you saying? If you leave Luffy will-"

"He won't do anything Sabo, because he has you."

"You're crazy. Where are you going? And do you think they will give you permission so easily?" Sabo was getting more and more desperate by the minute. It was true that he was mad at Ace for being unable to control himself but he didn't want him to leave heaven nor hell like that. In the first place Sabo was so mad only because he was afraid of the consequences that may fall on his sinning friends. However none of them seemed to remember about heaven's and hell's rules; and the simple fact of existing a demon in love with an angel was a great sin with extreme consequences already… Why couldn't they understand it?

"I've got permission already since I had been thinking about this for quite a while. Today when I came here I had planned to make it my last time. Perhaps because of that I was unable to control myself." Ace explained surprising the other man. "Don't make that troubled face, I'll be back. But now I really need to leave before committing a greater sin." Ace smiled gently yet sadly, feeling an unbearable pain in his heart just thinking of how much he would miss everything and everyone, especially Luffy. But that would be for the best; he knew it.

Sabo, on the other hand, sighed reluctantly, yet he faced the demon determined.

"I get it; I'll take care of Luffy like always. Be sure that you return. And don't do anything crazy!"

"Thanks Sabo. I'll return someday for sure. Until then I promise you that I'll get rid of these feelings, so we can go back to what we were when younger."

"You're an idiot. Just get the hell out of here and come back soon you stupid demon!" Sabo demanded frowning lightly while kicking the dark haired man softly as a way to reassure him.

Ace smiled at the blond and turned around on his heels in order to leave the garden. His black wings were magically spread in his back and the demon flied a couple of inches up in the sky, yet he stopped in mid-air suddenly with clenched fists and a painful pang in his heart. He looked down at the garden, in Luffy's direction, and observed the angel one last time. Ace knew that he was torturing himself with such actions, but he couldn't stop his emotions from overflowing so strongly. He would miss him so much… yet he had to fight against those forbidden feelings and distance himself from the angel.

A couple of seconds passed and finally the demon decided that he had to leave or else he would go back in his word and for Luffy that could never happen; thus the demon looked away from the angel, and faced forward more than ready to resume his way. It would be painful but he would endure it for Luffy, since he couldn't afford to let the boy commit any more sins without even being aware of them. Today he had committed the greatest of them all, so far: Ace had kissed Luffy, even if lightly he had felt those warm and soft lips under his. Yet, today had also been the day he had started his punishment; it had been the day he last had seen Luffy. For Ace it didn't exist worse punishment in the entire world. Forgetting about his love for the angel was a very painful thing, yet he needed to do it and in order to achieve that objective Ace needed to be away from the angel. Nevertheless he wasn't yet aware of how much his decision would hurt Luffy; whom he most wished to protect above all.

Again; sorry for the ugly mistakes QwQ ~

Bye~Bye, ❤ヽ(*'､^*)chuu*
