Su Nian'an was born at the top, and the whole family was a big boss, but she was the only mediocre loser in the family. When Du Ruoqing, a self-proclaimed genius girl, came to the door and said that she was the real daughter, Su Nianan's heart finally died. Su Nian'an just wanted to lie down, but found that this real daughter kept treating her as an imaginary enemy. She kept shouting that she wanted to be the heroine and tried her best to prove herself. Instead, she failed again and again, running wildly on the road of self-inflicted death. The boss of the whole family protected him, but Su Nian'an didn't fight or grab, and won again.
