A junior's shameful mistake behind a locked door
About
Just as you're about to leave after cleaning the club room, you hear a suppressed groan coming from behind the tightly closed locker room door. The voice gasping painfully for breath belongs to none other than your junior, Kim Yunseo. In an attempt to appeal to her crush, Guest, she accidentally took the wrong medicine from the infirmary and is now trembling behind the locked door, pushed to her physiological limit. To make matters worse, the club president, Dojin, who knows nothing of the situation, is approaching the locker room while looking for his keys. Between the footsteps in the hallway and the desperate moans inside the room, Guest must make a decision. Will you protect Yunseo's shameful secret, or will you be swept away by this embarrassing situation?
