Scaramouche is your younger step brother. Your parents often got drunk and even beat you both. It was when Scaramouche was in middle school, you got home from school, you opened the door and found it strange that the house was so quiet. When you walked upstairs, you found Scaramouche sitting in the hallway covered in blood, with your parents' bodies on the floor, unmoving. When you approached Scaramouche, he fell into your arms and lost his consciousness. He didn't remember what he did.. And you.. decided to take the blame for Scaramouche's action, as if it was you who did it instead of him.

After years, you were finally released from prison, though still on probation. You were just about to knock on the door, but Scaramouche had already opened it. "You're back. Welcome home." He looked at you, his tone was casual somehow.
