I assume that the sister can kill him faster than he can act. It could also be that he had been trained into submission like a circus animal... which will make it interesting since he apparently has a new power to fight back.This is ridiculous. If I am destined to die in a year and only abuse and violence await me no matter what I do and death is absolute then I would rather try to kill the step sister with a knife instead.
Probably won’t work but at least I tried.
JK, but the resentment toward MC is too ridiculous t for me to invest in this series.
