My Girlfriend Killed My Father in Order to Help My First Love Get a Promotion

In order for my first love to get a headline promotion, my girlfriend rushed into my house with the police. She asked me with a righteous look on her face. The reporter holding a camera behind her was her first love. "Comrade police, my boyfriend's father is the murderer who killed his own sister!" When my sister-in-law drowned when she was ten years old, it was a grief that my father could not overcome in his life. The report written by my girlfriend's first love forced my father to commit suicide by jumping into the river. Later she knelt in front of me and said that she was wrong, but I just wanted her to get retribution.
