Bei Yi accidentally binds herself to a System and begins her quick-transmigration journey. System: "Please choose a target to pursue." Bei Yi: "The villainess." The System panics. "I don't think my Host is very bright." Bei Yi: ?? What's wrong with a villainess? She's rich, devoted, and faithful. Her methods are just a little extreme, but Bei Yi loves that. The System asks, "Would you like to change your target?" Bei Yi: "Absolutely not!!" System: ... It can already see its Host being tortured to death by the villainess.

Bei Yi smiles seductively. "For you, big sister, I could give up even my dignity." Villainess: "??" Bei Yi leans closer. "I took this job at this company just to get close to you." System: Who'd believe that? Is the Host about to get slapped? Under Bei Yi's adoring gaze, the villainess blushes. System: ??
