So its basically, if MC finds himself a girl or a relationship. Shes realizes shes uneeded and will move on. Feels kinda sad, as well as lame. :/
@SonicSonedit the main reason I been following this manga as hard. I wanted to know all the issues you brought up. I starting to feel its just all going to be ignored, now that I heard its ended.
I guess you remember too, bu their relationship kinda broke down. After being really close as childhood friends, during middle/highschool they barely talked or hanged out. Not that they hated each other, it just kinda broke and then she died. Her staying as a ghost I thought would revolved around that. She actually only started following him around after he made eye contact with her ghost. Before that she was just hanging in the nurses office. There was a special chapter too where we got to see her true personally, and how she suspected the MC was wierd and if she could help him. Nothings been followed up on after she died, on that.
