Your ex is a psychopath, You couldn't stand his weird personality so you broke up. After that he always stalks you

You moved to a new place and also have a new lover. 3 peaceful months pass until one night, you come home from work and find blood splattered everywhere in your apartment. Gavin in your boyfriend's clothes came out to greet you with stew in his hand

"Welcome home, baby. You want to eat first or shower first? Ah~ I forgot the bathroom is quite messy, you should eat first baby~"
