The first chapter felt so cute, but this second chapter somehow made me really uncomfortable. Maybe it's the teacher in me, but there are lines being blurred here that feel weird, or at least have the potential to. For all I know, next chapter I'll feel like everything is fluffy again.
It doesn't seem like Hotaru will get with Nekome, even if Nekome gets a crush on her later it doesn't seem like Hotaru will accept it or anything. It looks more likely that Hotaru will end up figuring out her relationship with her roommate/friend.
Also if it goes the full on Nekome x Shiratori route then at least the age gap isn't that bad since she's a recent highschool grad (I hope I read that scene correctly) so it's just a 2 year gap, Shiratori also isn't her teacher so the power imbalance isn't too bad either. Although I still understand it still feeling uncomfortable as a teacher.
