Wtf! I feel sorry for Chiho-san having to deal with lot of garbage person, and wth is wrong with the MC it's a huge turndown now...shit really wth is wrong with him, I can understand if he just crying silently without letting a voice out...but hell he's crying loudly, and that's it how Japan known as virgin country. He's no better than her ex-boyfriend such a bitch.
