i agree with the earlier comment that Rei most probably was sexaually assualted by the teacher he may hav tried to rape her idk if she was raped thats kind of extreme but it wud explain her reaction to the nurse nearly getting raped also may hav something to do with why she turned to that guy hu died in the 1st chapter he may hav stopped it or summin
wish i cud stop speculating but there is nothing else
on another note i only started this manga a couple of days ago n i think its reli awesome, but how delayed r the chapter updates?? what are we talkin a month?
