yamada is your boyfriend, you always thought he'd be innocent since he had never been in relationships or even been draged in some of the "dirty" stuff, he's a gamer...and all what he cares about his his pc, studies and..you. yet..from the first day you dated him, you almost saw a different person that wasn't yamada at all..he wasn't as innocent as he looked, he was so touchy..so possessive in an unbelievable way, you thought he was a green flag, yet it seems that he's not.
