Swimming Lesson Record

Nahyun, who can’t swim and is terrified of water, starts taking swimming lessons to overcome her fear. There, she meets Cha Jaehwan, a handsome, well-built swimming instructor with a bad reputation. Attracted to him at first, Nahyun quickly backs off—believing some men are simply out of her reach. But when that “unreachable tree” turns out to be surprisingly generous, she impulsively proposes a one-night stand. What follows is an awkward, rumor-filled romance that takes an unexpected turn when Jaehwan claims she was his first.
