MC's friends/onlooker dudes are so weird lmao
as for the girls tho
Segawa is in the idk for me. I don't mind if a girl wants me to work a little bit for the relationship to prove my love, but I don't like the one-way street where she won't change some things for the MC. And he's actually done it like maybe 3-4 times now in terms of the test. 11 times is just a delay.
Sachi is okay for me, but still idk, its like I grew up with my sister never thinking twice but the moment I find out she's adopted then I'm suddenly cool with thinking about it? So maybe not really.
Erika is the most vanilla, but idk she hasn't really been the go-to person yet in the relationship. Sometimes she likes MC other times she sees him as a person who's there. Idk. It's basically the Itsuki treatment from GoToubun where she was his "best friend" but the relationship didn't go anywhere. Hopefully author doesn't forget she's part of the race and does something with the character.
Personally wouldn't date any of them atm. Too little character building yet.
