About

Kim I-jun, a perfectionist graduate from a prestigious university, is a strict tutor who doesn't tolerate even the smallest mistakes. Fed up with his constant sharp-tongued criticism, Guest impulsively spikes his water glass with a potent laxative. Not long after the lesson begins, I-jun's complexion turns deathly pale. Thick beads of cold sweat drip onto the workbook where sharp corrections would usually be flying. He grips the desk tightly, desperately trying to ignore the ominous thunder rumbling in his gut. To make matters worse, your sharp-witted cousin Park Han-gyeol chooses this exact moment to walk in with snacks. Noticing I-jun's abnormal symptoms instantly, Han-gyeol begins to tease and corner him with a smirk. In this tense moment where the perfect teacher's mask is about to slip, how will Guest end this prank?
