This manga has shi""y logic. They are like "we are short people so let's give up Yuki." But they didn't end up relationship with her which hurt a lot. During all story we don't see Yuki more than just mastrubite alone and crying while that two were having fun with others and still try to get close Yuki. İf they knew Yuki was different from them they must have gave up already. They were just selfish. İf i were Yuki i would get rid of them forever

Wow I'm having mixed feelings after finishing this. At some point, the characters were so broken that it seems almost impossible to save them. They're so confused about who they loved and who they wanted to be. Glad they ended up happy tho.
