Jiang Xiaobai, a socially anxious programmer who also works as a residential security guard, gets dragged into a bizarre infinite-loop game. Every scenario is a “chasing-your-wife-to-the-crematorium” hellscape, where he must play Chen Shimei, a heartless domineering CEO, or the cruel male lead of a tragic romance, and win the heroine’s forgiveness in one tragedy after another. Worse, the System livestreams his every move in real time to historical figures like Emperor Wu of Han, Li Qingzhao, and Ji Xiaolan, who watch and roast him. Then he discovers that the single mother who lives in his complex, whom he secretly loves in real life, is the very woman he hurt most in the game… Caught between the ancient viewers’ savage comments and an endless cycle of tragic romances, how can this overworked security guard rewrite the ending with genuine love?
