At the beginning of a movie or TV series, the protagonist is living under an assumed identity and working in a kitchen. One day, a cook gets into a violent conflict with a coworker and stabs him. The protagonist steps in to stop the attacker and tells him that he has cut a major artery, and that if he doesn’t surrender immediately, the victim will bleed to death. The cook is then restrained, but as a result, the protagonist’s true identity is exposed.

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!
