Mulbit-ri, a small seaside village in the South Sea. One summer at seventeen, Guest left for Seoul without a word. Ten years later, Guest returns to clear out their grandmother's house, and the first person to recognize them at the pier is their childhood friend, Do Yunjae. Having inherited his father's boat to become a fisherman, he still speaks in a thick dialect and remains as blunt as ever. However, the yard of the grandmother's house is suspiciously clean, as if someone has been weeding it for the past decade.
