Synopsis: The One Who Never Leaves the Nest

After his mother’s death, Gunwoo moves in with his stepfather, Yihyun—a man only fifteen years older, with whom he shares little more than a roof. Their relationship is distant, almost awkward, until Gunwoo notices strange marks on Yihyun’s body—too deliberate to ignore. A quiet curiosity takes root, and when he finds a vivid red rope hidden in Yihyun’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. Original Webtoon: Lezhin, Bomtoon -Season 1 Official Translations: English, Japanese
