On a dark, quiet night, as Se-a returns to her empty home, flickering lights reveal a man in a cap standing at her doorstep. He calls her name, and when she turns, she's stunned by the familiar face: someone she believed had died ten years ago. Letting him in sets off a chain of unraveling truths, buried secrets, and painful misunderstandings. But he's not the only one hiding something. As past and present collide, can the two mend the distance that time and silence have carved between them? (Source: Webtoon Entertainment)
