Plot Summary of Window to Window

Childhood friends Ginu and Yubin live in separate apartments in neighboring buildings—so close that they can see into each other’s rooms and chat through their windows. Their casual friendship takes an unexpected turn when Ginu accidentally catches Yubin in a rather intimate moment through the window, exposing a secret Yubin has kept for years. As their dynamic shifts, emotions they’ve never acknowledged begin to surface, blurring the line between friendship and something more.
