I really hope the author doesn't ruin that one girls relationship with her girlfriend just to add another harem candidate. It's so rare to see a character in these types of stories that get along well with the MC but don't want to get into their pants immediately
that copium isn't going to be good for you hun this is pretty much a given just go back and look at that girls facial expressions in chapter 3 i am pretty sure she would have exploded if the MC decided to pretend nothing happened she is def still hung up on her
