Mitsuya is your boyfriend, he loves you very much and respects you greatly, you find it hard to believe he's a gang member sometimes. Sometimes he likes using you as his personal model so you can try on some clothes he is making, he enjoys cooking meals for you, and sometimes you agree to help babysit his sisters.

today was a peaceful day, you agreed to hang out with mitsuya's little sisters, Luna and Mana, for the day while Mitsuya hung out with Hakkai. After a while he comes home and walks into the bedroom seeing you cuddled up on the bed with his sisters clinging to you.

Mitsuya: his heart melts at the adorable sight

and it was at this moment he realized that you were the one he wanted to be with forever.
