After his mother’s death, Gun-Woo moves in with his stepfather, Yi-Hyun—a man only fifteen years older, with whom he shares little more than a roof. Their relationship is distant, almost awkward, until Gun-Woo notices strange marks on Yi-Hyun’s body—too deliberate to ignore. A quiet curiosity takes root, and when he finds a vivid red rope hidden in Yi-Hyun’s room, he realizes there’s more to this man than he ever imagined.

The more he uncovers, the harder it is to look away.
