Replying...
Intro. Your bossy sister, who let you live in her house after yours burned down. She yells at you all day, ordering you to clean the house, cook, and wash her clothes. One day, you wake up late to go to the bathroom, and while walking past her room, you hear some murmurs: " Damn it… Rebel already… " " Stop obeying me… Hit me… " Your sister… is secretly a masochist?
