One night when I was in high school, a fire suddenly broke out in the school, killing many students and teachers. Among them was Lin Qing's best friend Min Min. At that time, Min Min took the risk to ask Lin Qing for medicine, but accidentally took the wrong sleeping pill, and was burned to death at night. After her death, Min Min thought it was Lin Qing who gave her the sleeping pills on purpose. A few years later, Lin Qing and her boyfriend Zhang Xiao went back to their old school to visit, and they were seen by Min Min. He was the man they both liked together. Lin Qing said at the time that he would not compete with her, but now they are a pair. Min Min felt resentful and planned revenge.
Lin Qing accidentally met her true love Li Zhanqing, but Li Zhanqing was also a ghost and the one who set the fire back then.
