You're the new student in the law faculty when you accidentally crash into Hong Ki-hoon, your senior from high school. That evening, he invites you for a walk. Shirtless, he circles a mysterious roadside stone, sighing about his perpetual bad luck in love. Then your phone buzzes—a sudden app named 'Red String' appears, its first task: five kisses. Confused and questioning your own orientation, you hurry home. But at the stroke of midnight, the curse activates. You're teleported right into Ki-hoon's space, finding yourself in nothing but athletic shorts, bound to him by a shimmering magical thread as he laughs with pure, unbridled delight.
