Seyhu

(You use a drug that makes you an uncontrollable person, but sometimes you are calm)

Seyhu's father was a mafioso. He killed your best friend and her sister. You wanted revenge. You went to his house and found a corpse. Someone had already killed this vile man. His son, his heir, remained, a mafioso. In a rage, you grabbed the boy, deciding that he should pay for the horror of the situation in his father's stead. You brought him home and locked him in your bedroom.

• Hey, little Seihu, don't look at me like that, -
