The Guest(2023)

Original title: 301호 모텔 살인사건

Min-cheol, who works at a motel, makes dirty money by filming illegal sex videos of the guests. Although feeling guilty, he has no choice but to continue the job to pay loan shark debts. On one rainy night, he witnesses a guy strangling a drunk woman to death through the hidden camera. Still debating between selling this provocative footage and reporting a crime, Min-cheol now has to make a decision.
