As a true over-bearing president scum gong, when Xie He for the Nth time rejected his admirer, he heard a sentence in his head: “Congratulations on achieving the “rejects 100 hosts” accomplishment; as an award you will soon bind to the “Scum Gong and Cheap Shou” system, entering other worlds to complete capture missions.

As a scum gong, Xie He expresses that it is very easy to hide one’s true colors, but…“I Heard My Boyfriend’s Brother Secretly Loves Me,” “Teacher Love Me One More Time,” “Raising Youth Manual,” “Your Majesty, This Servant Obeys,” “The Tyrant Lord’s Substitute Lover,” “Captive of the Empire,” “Disciple’s Cultivation Furnace”…
