Well that was a surprisingly sweet and thoughtful chapter and also fuck you for the volume tease author-san:
Also, who want's to call how many he end's up actually having sex with
Tsubasa (programmer) - I think they gonna bang but just casually. Likely involve some alcohol. May even be the first one to strike.
Mio (idol) - I don't think they will go all the way without a time skip. Which for Kei is very possible. But they will just at most start to get under her tsun layer. Gonna be a while.
Anju (vagrant) - she's banging at some point. I think the wheels are already set in motion there, just need a few more interactions
Yukari (pole dancer) - probably not, ironically enough. If they do it will probably be some kind of pity dance to cheer up than anything romantic. That's the vibes I get. But hey there's still plenty of story and Yukari hasn't come across a huge problem yet. Things can change.
Lili (artist) - oh they banging. He may have resisted now but the sparks are already in the air. She just needs to build up some confidence in herself and her work and boom. She'll grab what she wants.
Hayato (the bro) - lol, mostly kidding. But we know there will be drama and now bros talking about marriage. You just know whoever is hooking up with Hayato is probably gonna cook on the MC on the side. Easy drama bait while being able to cast that mystery girl aside if it's too hated (or make her another main character if they want).
