I think I have postponed this long enough. My answer was purely based on how many people wanted it. I hope you like it. Enjoy.

Kai Baby-sits

Chapter 12: Gone with the past

Kai knew the answer was in front of him. He really did know. It was just what outcomes would occur that bothered him. He was not sure if he could tread the path he would choose. Kai propped himself up on the grass, staring at the sky thoughtfully. He knew he had changed. His past self was not his present self. The differences were many. His past self would never even intend to meet Miwa's sister, let alone watch over her for however long he had. If he had changed, then wouldn't the correct answer be to just accept it?

Kai sighed, his face having a slight grimace. The sound of joining a family was confusing, if not unwelcoming. Kai did not want to be adopted. Not in the slightest. Because the package came with foster parents. Replacements. No one – Kai repeated – no one could ever replace his parents. It was just impossible. He knew it would be unfair to Miwa's parents if he accepted with those thoughts in mind. Still, he had to move on. There was a difference between the past and present. The past was gone, but the present was still there.

Kai stood up, brushing his pants off. He had his answer. The answer was no different than the one he had one the problem made itself known. His past self had been a solitary figure, someone who never had anyone and pushed way the last ones who were around. But time changes people. Kai no longer clung to the so past. For once, the future road held promise. He would just let things go the way they were headed. The answer was as simple as it had always been.

Kai smiled as he left the park, his footsteps smooth and confident, the opposite of how it had been on the way here. He knew it would be problematic. But he could handle that. He had agreed to almost everything Mana had said up until now. A little more would not be a problem.

As Kai reached the house and knocked on the door, he wondered how people would react to this knowledge. After one probability, Kai decided to just let something called luck work its magic.

"What are the chances of Miyaji Academy going on a field trip?" Miwa exclaimed, shaking his head as he left the school with his sister and Kai. Miwa wasn't sure if he could call him that anymore. As if reading his mind, Kai shot him a look.

"I'm living with you guys, not being adopted," Kai stressed clearly, thanking whatever made everyone busy this week. Satoshi was visiting his family with his sister, out of the city. And Kamui, Morikawa, and Izaki were also out of town. Really, Kai wondered just how lucky he was.

"Isn't it the same?" Mana asked, grinning beside him as she mentally congratulated herself for pulling it off. Her parents did not mind at all, having grown found of Kai, though, Kai himself still acted weird around them.

"No," Kai responded frankly.

"Well, when you're ready to change it, let us now," Miwa grinned, slapping his shoulder.

"If you call me by my first name, I'll call you by yours a hundred times over," Kai warned, his eyes twitching.

Miwa quickly raised up his hand in defeat. "Alright. What, am I the only one who calls you by your last name now?"

"I never allowed Satoshi to call me that." I'm amazed he's actually older than me, Kai sighed, but he was content. He wasn't sure if he could deal with everyone's questions and shocked faces. He still needed time to adjust to everything. But he had to admit, it was a little nice.

"But you let me," Mana smiled up at him, happy that he allowed her to, and even if he didn't she would still do it. Mana giggled at that.

"What are you laughing about?" Kai asked with a slightly raised eyebrow. He thinks he already knew what it was.

"Nothing~" Mana sang innocently, grinning from ear to ear. "Can we go straight home?"

"So you can eat cake," Kai and Miwa finished in usion.

The spiky-haired boy gave a look. "You're just the same."

Miwa laughed, scratching the back of his head sheepishly. "Guess it runs in the family."

Kai turned away with a scoff, but he slowly opened his eyes with a smile. He was now part of that family. That thought was not as bad at he had thought. Maybe he could get use to this. After all, a family never chose its members; they just had to live with them.

"Toshi-nii!"

Kai blinked, looking up with a start. He realized he had stopped walking.

"Kai! You coming?" Miwa called to the brunet with a knowing grin. He knew Kai caught what he meant.

Kai returned something that could almost be called a grin as he caught up to them.

"So you don't mind sleeping on the floor?" Miwa asked the brunet who merely shrugged.

"Either way is fine," Kai told him.

"But I want you to sleep on the bed with me and Onii-chan!" Mana gave him a frown.

"All of us won't fit, Mana," Miwa chuckled at his sister's unhappy look. "We could take turns?"

"No," Mana huffed, shaking her head. "We'll sleep on the floor."

"Why do you have separate rooms?" Kai whispered to Miwa who just laughed sheepishly.

Mana lay in between the two boys and was the first to fall asleep, hugging her brother's arm. Kai and Miwa shared a smile before turning opposite ways and closing their eyes.

Kai stared up at the now dark ceiling. He wondered how everyone he knew would feel about this. He wondered how Miwa's family felt about this. Kai couldn't say. He was not sure what to think about it himself. It was strange, but he never actually considered living with people other than his family (not even that) after his parents died. How would they feel about this?

He sighed softly. He wasn't even sure how Miwa's family felt about him suddenly living with them. Their parents probably agreed just because Mana and Miwa had asked. He didn't belong-

Kai stopped his train of thought as he felt something tugging his arm. He slowly turned to see Mana, pulling his arm closer. Kai couldn't tell if she was aware of what she was doing in her half-asleep state.

"...Toshi-nii...I'm happy I have another brother," she murmured, closing her eyes again and smiling happily.

Kai stared at her as he digested her words. He looked up when he felt eyes on him.

Miwa gave him a smile, rather than his usual teasing one. And it finally hit Kai that Miwa would now be his older brother (!).

"Welcome to the family, Kai."

And Kai realized that just by him baby-sitting Mana, he had gained a new family.

I think this may be the end. I thank everyone for the wonderful Reviews and support! It really did help! I may actually work on a continuing story with Kai dealing with his new family. In any case, thanks for all your help!

Review if you liked my story!
