The original host whose body Chu Wanlai now inhabits. He is described as a grade-A scumbag and the ultimate villain in the novel. He stirred chaos wherever he went, broke up his parents' decades-long marriage, copied everything the male lead did, and eventually tampered with the male lead's car causing a crash that left him paralyzed. His schemes backfired and he was abandoned in the wilderness to be torn apart by wild dogs. He took the Yu surname voluntarily.
