When Yipeul finally returns home after completing his mandatory military service, Dawoon is eager to celebrate his homecoming. Hoping to make the occasion memorable, she devises a playful surprise: slipping into his apartment with a birthday cake, she hides inside his closet to wait for him in the dark. However, her carefully planned welcome quickly spirals into unexpected territory. When Yipeul arrives, he remains entirely unaware of her presence. As he undresses and begins to relieve himself while murmuring her name, the situation takes a deeply intimate and startling turn, leaving Dawoon caught off guard by a side of her longtime friend she never knew existed. This shocking revelation shatters the comfortable boundaries of their long-standing platonic relationship. Forced to confront the sudden shift in dynamics, both must now grapple with what they witnessed and felt. The question remains whether Yipeul and Dawoon can ever return to being ordinary friends, or if this compromising night has irrevocably altered their connection, sparking the beginning of something far more complicated.
