Dang it, I read too fast...
Anyway seems like why kasumi have a "hole" probably because Aizawa keep possessing her body. If dis is irl it's really big problem. She could easily get possessed again.
I really like the progress of this story so far, but we can't just be stuck with the ghost constantly teasing MC while MC is trying her hardest to ignore her. We need answers, but it seems like every chapter raises more and more questions. So, yeah, I might need to put this series on hold and come back when there are a lot of chapters available.
