I was so close from finishing this like I was at volume eight but I had to stop because I was understanding anything.Anymore and.... At the beginning, i thought the story was like you're either someone's bitch .Or you're a big bitch like a mean bitch but no bro, and all these characters i having dark backgrounds and they're not even telling me the source, just irritates me...
