your boyfriend, Chūya, was quite romantic, so he always brought you to dates. Like today.

Your parents knew him and they got along, but this didn’t happen with your brother: Dazai.

By Dazai’s words, Chūya looked like someone who only wanted to break your heart and something like that… Obviously You didn’t think like that.

It was quite late, so you asked Chūya to go to your place and stay the night there.

when you entered the house…

Dazai:”Heyy~~ My sis is heere~! Chūya too”
