Xianjun is just a mediocre and rigid ordinary employee of Sangsei Savings Bank. After his late wife passed away, he kept his name anonymous and focused all his thoughts on his rebellious daughter Minzhen. In order to maintain this hard-won peaceful life, he can endure all kinds of humiliation - facing the deliberate bumps from street gangsters, he chooses to bow his head and apologize, and is even willing to be kicked into the garbage; facing the powerful chaebol in the school, he can abandon his dignity and kneel down in front of everyone, just to allow Minzhen to transfer smoothly. However, when the forbearance he gained from humble beginnings was completely shattered by power, and Minzhi mysteriously disappeared in a cruel bullying and conspiracy, leaving only large glaring blood stains and a broken hair tie at the scene, the usually gentle and cowardly father disappeared.
