"What's the matter, Aichi?" Kai looked up from his textbook, when he noticed that his cat (his boyfriend) curled up in a ball, facing the wall, his tail flicking gloomily.

"…Kai-kun is so mean…" Aichi pouted, as he padded over to where Kai is, tears brimming his eyes. "You won't play with me at all…"

"I told you that I have my finals, and I have to study…" Kai rolled his eyes, petting Aichi gently. "I'll play with you lots and lots after it's over, okay?"

"But I'm lonely, nya~!" Aichi whined, his hands curling into fists.

"I get it, I get it…" Kai let out a defeated sigh. "Come here, Aichi."

The cat's eyes shone as he leaped onto Kai's lap. Kai's chair almost toppled over when Aichi did so.

"Careful," Kai warned, putting down his pencil to wrap his arms around Aichi's waist. The cat licked his cheek happily, bouncing up at down on his lap excitedly.

"Geez…" Kai pulled Aichi closer to him, patting his back. "You're such a pain…"

"Kai-kun…" Aichi nuzzled his head in the crook of the brunette's neck. Kai then turned his attention back to his textbook.

Aichi stared up at Kai's determined face curiously.

"So cool…" he whispered to himself, his eyes gleaming. Kai-kun's serious demeanor is one of his favorite things. Aichi clawed on Kai's shirt. He glanced up at Kai again. The brunette's attention did not even waver.

Aichi smiled. He really likes this part of Kai-kun.

Aichi pressed his face against Kai's chest. It was really warm. He really wanted to press himself closer to Kai-kun…

Aichi lifted up Kai's shirt, and pulled it over his head. Now he's in Kai's shirt, his face pressed against Kai's bare chest.

"Sooo warm~" Aichi mumbled, his cat ears flicking happily.

"Aichi, what are you doing?" Kai stared down at the cat, who grinning widely is in his shirt.

"It's warm like this~" Aichi sang, pressing himself closer to Kai.

"You're going to stretch my shirt," Kai complained, as Aichi poked his head out of his shirt. The boy gingerly stared up at his boyfriend, and planted a kiss on Kai's chin.

"Stop that," Kai pushed Aichi's head down, as Aichi retreated into his shirt, meowing.

"Nee, Kai-kun, give me attention~~" Aichi pouted, his tail flicking around in Kai's shirt.

"Oi, that tickles!" Kai hissed at his cat, throwing up his hands. "Look, if you won't stay still, I'm just going to bang you senseless so you'd be asleep 'til tomorrow."

"Okay~" Aichi's eyes sparkled, his ears perking up happily. "Do it, Kai-kun~! Bang me senseless~!"

Kai groaned, face-palming himself. "Even though I want to, I have to study…"

Aichi thought for a moment, a pout on his face. "…Okay. I understand." He squirmed out of Kai's shirt, and jumped off Kai's lap. Before Kai could say anything, the cat walked out of the room.

Now that Aichi was not present, he could finally focus. He stared down at his textbook, and he was about to study, when he realized that he COULDN'T focus at all.

Kai felt so empty now that Aichi is away. He realized, he needed Aichi to be in his arms…The softness of his skin…the warmth of his body…his scent…Kai wants to be close to those things…
Kai slammed his hands on the table, and stood up.

…And so Kai walked out of the room, calling for Aichi.

Then he came back into the room with a satisfied smile on his face, and a confused Aichi stuffed in his shirt.

Short thing.
