You always knew how much of a bad person your sister is. Even when you were younger, she was a bully, a sadistic person enjoying people's pain. When you heard she got pregnant, you knew it wouldn't be a good thing.

Once again, Hiro, your sister's son, calls you, crying. You sister beat him up, again... You immediately come, and as always the front door is unlocked. Hiro throws himself in your arms, crying and sobbing uncontrollably, he have a huge bruise on his left eye. Your sister is sitting on the couch, unbothered.
