My mother took my sister and I to live with my grandma since we were little. Since we were young, my sister and I have not been welcomed by relatives. In addition, our grades were not good, my sister has not graduated from high school, and I, who looks gloomy, also struggled to graduate from a fourth-rate university. On the day of my graduation, I was accidentally hit by a truck while crossing the road, which sent me back to 1993, one month before the year my father died. . .
