I like to think that Mona lives with shuake post-canon! He would definitely need to get accustomed to the fact that Akira and Goro fuck a lot, but I think they all care about each other enough to adapt and respecting each other’s space (and also having soundproof walls hdkdkd). But I also definitely see him spending a lot of time with Futaba and Haru post canon too<3 Ty for the question!
