“Jong-il! Why don’t we move in together? Let’s just do it!” Dajeong, 32, proposes to her boyfriend Jong-il, 35, while he is belting out “Confession” in a coin karaoke room. Lacking the confidence to build a stable family, Jong-il presses the “skip interlude” button — and their relationship ends there. The next day, while working a delivery job, he arrives at Dajeong’s apartment and sees an unfamiliar man’s hand reaching out to take the food. Jong-il turns to his two best friends: Sung-yeong, a long-term civil service exam taker who blames him for choosing “Confession” in the first place, and Jeong-seok, a convenience store owner who values logic over sympathy. But as the three men talk through what happened, they begin to notice one strange detail after another. Then they learn that Dajeong has cut off contact with everyone after texting her workplace to say she is taking a long-term leave. Determined to uncover the truth, the three friends begin tracking her down.
