life. As she walked down the stairs, she met Yuichi waiting for her, who warned her of work punctuality. Yuichi led her to wait outside the shop, and happened to encounter an oyster-shaped harmonica. As he played a song, Ji-soo overheard it and thought of the moment Dong-joo drowned while trying to retrieve the harmonica. She rushed inside, only to see Yuichi playing the harmonica.
