With no way to investigate, the story unfolds strangely with the sudden appearance of a woman... Where did she come from, and what will happen to her in the future? My name is Qin Keying. I was born in Shanghai in 1981. I am the youngest in my family. My father is the head professor of the Chinese Department of Fudan University in Shanghai. I like to study ancient poetry and have good calligraphy. Mother is a famous pianist. I was born an art historian, but I have no artistic talent. Graduated from the Shanghai Theater Academy and now works as a special pianist for a radio station, barely avoiding becoming an old man. One winter when I was 27 years old, I met the woman who changed my destiny. Was she here to collect debts? Or are you here to pay off your debt? Did the nightmare begin like this?
