Slip Up

At the university's opening assembly, Do-Hun unexpectedly encounters ‘ae-Hyeon, a special person from his middle school days with whom he shared a deep bond during a brief period. However, Jae-Hyeon not only fails to recognize Do-Hun but also carries rumors of sleeping around with multiple men. Hearing these rumors, Do-Hun impulsively joins Jae-Hyeon for drinks and ends up having a one-night stand with him. Using the one-night stand as leverage, Do-Hun blackmails Jae-Hyeon into agreeing to have sex only with him. He then demands various acts like using sex toys and cosplay, humiliating him and marking the beginning of their twisted relationship.
