Zhao Tiancheng and Shen Zilang were friends who met in the orphanage, but their fates were very different. They were adopted on the same day, and eighteen years later, one is a young man from a wealthy family, and the other is a bartender.
By chance, a murder case involving many years was involved, and the mystery of the two people's life experiences was also revealed. Former friends turn against each other, and jealousy and hatred distort human nature. After being framed and imprisoned, Zhao Tiancheng, who lost his lover, vowed to take revenge, but gradually lost his true nature in the process.

Purpose: Human nature is inherently good and inherently evil
