Jeong Hae-deun, once a high school swimmer, now works at a swimming center. When Han Si-oh lies about a leg injury that supposedly keeps him from swimming, Hae-deun is tricked into letting him stay at his place.

Si-oh, who has liked Hae-deun for a long time, seizes the chance and refuses to stop making advances...

“I want to spend all day licking and sucking you, I want to take you, and I want to fill you up until you’re completely mine.”
