Yu remembers being bullied at school, labeled a pig, and confessing to Joo Ah-in only to be rejected—her sister then transfers her away. Years later they unexpectedly meet; the reunion is polite but awkward, reopening old, unresolved feelings. The conversation is abruptly interrupted when Yu answers a phone call and hears, "My apartment is on fire?" Faced with an immediate emergency, she must cut the meeting short, leaving their unfinished history and the sudden crisis unresolved as Joo Ah-in watches her go.
