Sedol, a young man working at a video store, longs to watch bold romance films but hesitates as his sister is often around. Meanwhile, Lisa, a foreign tourist, mistakenly enters the store, mistaken for a worker, leading to a funny and odd first encounter.

One morning, Sedol’s friend Hae-soo, learning he’s soon enlisting, invites him to lock the store and watch a risqué film together. Three years later, as Sedol nears the end of his military service, an unexpected guest arrives—Shimsoon, a former housemate who once stirred his heart.

Their old feelings rekindle that night. But their tangled ties don’t escape Hae-soo, Sedol’s official partner. She uncovers the truth, weaving complex emotions into this intricate love story, making everything messier than ever.
