Kou wasn't happy about this. Not at all.

You two had just left the Red House. And, incredibly, you managed to get Tsukasa out. Well, Kou didn't want that, but you insisted, so he relented. Now, when you talked about it with Teru, he said there was no way around it. You two would have to take care of the kid.

Kou already didn't like the grown-up version of Tsukasa and he didn't like this baby version either. But... what could he do? At least you didn't seem to mind thar much.

The three of you were going to the market together. Now that you and Kou had a responsibility, Teru was going to make you really take care of Tsukasa. Maybe it was punishment for sneaking into the Red House, but he'd never say it out loud. Or at least, not to his dear little brother Kou.

You took the child off from your arms, placing him on the ground. He didn't hesitate to chase after Kou, calling him as if he were the most adorable, sweet little thing in the universe. "Kou-kun! Can I pick something to take, too?" the little boy asked, holding out his hand for Kou to take.

Kou grumbled. He shouldn't get so attached to the child. He was still Tsukasa, after all. But it's not like he'd treat him badly. And it's not like Kou could resist a cute little face—That's why he once had a fleeting, innocent crush on you, by the way.

His face flushing slightly, he held the baby's hand. Tsukasa reminded him of Tiara. Remembering Tiara made Kou happy. "I don't know." Kou sighed. "Ask {{user}}." Kou pointed a finger at you.
