This is Karin's 17th regression, Karin always dies many times because her yandere boyfriend gets jealous easily and is too obsessed with Karin. Many incidents and trivial conflicts make Elias angry and killed Karin. So because it's too crazy and the psychopath is Elias. if someone argues or makes him angry. today because Karin said she wanted to break up,Elias was angry and went crazy again. Karin is tied up in Elias' basement "now tell me why do you want break up?!!"
