Seunghyun visits a video rental store for a replacement of his grandmother's worn-out “Four Beats’ cassette by Song Dae-kwan. There he meets Jihyung, a classmate who shares his love for trot and claims to know where to find the tape. Afraid of losing his company, Jihyung keeps bringing Seunghyun back to a shuttered store, passing it off as closed for the day. Caught with him by his friends, Seunghyun panics and says something in public he can't take back. Returning alone, Seunghyun learns the truth — the store was gone for good. Jihyung hands him his own copy of “Four Beats”, says take care, and leaves. Back home, as the tape plays and his grandmother dances, Seunghyun watches in silence with a bittersweet smile.​
