The reason why i dont think he's a yandere its cuz i read the novel and i know whats gonna happen (● ̄(エ) ̄●) Ken Yamari
oh well.. i just saw some spoilers in the comment section and they labeled him as such. then maybe he is just.. too possessive or obesessive or smth? is that the right term?
no wonder he became a yandere... dude i would probably have some mental damage too if i was treated like shit Σ(  ̄□ ̄||)
