I don't see how it's selfish. She's just telling him how she feels. As of right now he's not in a relationship with anyone anyway.
I think its selfish because she already knows he likes endou and knows hes gay... if you have a gay friend would you confess to him? I at least wouldnt because id know i wouldnt stand a chance and that it would only make things awkward between us
Things will be awkward anyways... My friend confessed to me even though he knew he had no chance, that way he could turn the page (he has a girlfriend now)
I so relate to the friend (hair dresser guy) cause he totally sees whats going on and he tries not to bother them but holy fuck that chick knows endou and tsuda like each othet but she does that anyway? Thats nothing but selfishness in my opinion (╯°Д °)╯╧╧
