Kang Taehwa, who was a loan shark in a port city in the southern seas, reunites with his first love, Moon Chunghyun, after 10 years, as a loan shark and a debtor. Chunghyun, who was a promising pianist, appears as a debtor who has taken on his father's debt. Tae-hwa is not pleased with Chunghyun's ruined appearance, so he lends him money, but he lingers around him out of discomfort.
