A self-deprecating widow I'm sorry for forgiveness...

Saori is a wife who lives an ordinary but happy life with her husband and father-in-law. When I sent my brother-in-law, who was drinking at home as usual, Saori decided to drive the car that her husband normally drives because she was drinking. Saori is nervous after driving for the first time in a while, and her hands tremble and unfortunately causes a major accident. My brother-in-law suffered serious injuries that caused me to break and... my deceased husband. After causing an irreparable accident, Saori finds the value of living by being crushed by guilt and tormenting herself...
