To the casual observer, Taesung and Haeun appear to be genuine siblings. They have indeed been brought up together, sharing the same home since childhood. However, here lies the truth: they are not biologically related. Haeun has been living with Taesung’s family ever since her parents moved abroad, a situation that has persisted for the past 15 years. At this point, they are practically like real brother and sister… until one day, Taesung learns a prank from his friends. By grabbing a girl’s sides, one can gauge her true feelings based on her reaction. That evening, Taesung decides to test this out on Haeun, eager to see her response… and inadvertently ends up grabbing her breasts. Oh no. But what’s going on with Haeun’s reaction? She’s blushing, fidgeting, and remains silent… Is this typical behavior in front of your brother? Revelations unfold, and Taesung begins to view his “sister” in a new light now.
