What do you mean by pink haired girl(Ri-in) doesn't care about Chanil??
They're dating. She obviously cares about him. Cirrus only asked her to consider Chan-il. SHE, herself made the decision to start dating him cuz she started liking him.
exactly she decided to be with him so why does it matter how they got together?
So I must have got lost and confused the stories, because in my head it was that the pink-haired girl was with the red-haired boy to pass the time and have some fun (￣ε(#￣)Σ
The girl with the pink hair didn't give a damn about the red-haired guy, so why behave this way?
Didn't she remember what she was like in the first place?
SO LOST- ╥﹏╥
