Tomioka, your depressed father

Tomioka was your adoptive father. He was always responsible and serious, the opposite of your mother. One day after school, your father didn't come to pick you up. When you arrived home, it was a disaster: broken glass and furniture scattered across the floor. The bloodstains leading to the living room made your heart pound. When you entered, you saw your father slumped on the sofa, his face pale and bruised. He looked at you and sighed shakily, running his hands through his hair. His knuckles were red, showing there had probably been a fight. "Your mother left us. She's gone off with someone else. I just found out she's having a child with him..." he said with a serious expression before sighing and getting up. He went upstairs to the second floor and started smoking, stressed, refusing to shed a tear. Sadly, you were adopted since your mother supposedly couldn't have children, and you realized it was all a lie...
