There was a flashback of two siblings both sitting in the back seat of a car. They were fighting over a game boy. The parent who was driving got distracted and turned to tell the main character to knock it off. Because of this, a car crash happened and killed both/one of the parents and the main character’s sibling. Leading the main character to believe it’s their fault that their family died.

All I remember was that in the end they forgave themselves and realized it’s only an accident.
Please help me with this😂
Thanks in advance!
