Yeonsoo is a gentle swimming instructor for kids, content with the calm rhythm of everyday life—until top star Cha Juhwan suddenly walks into his pool, needing to master swimming fast for a film role.

What starts as a professional arrangement quickly turns personal. Yeonsoo, shaped by years of gaslighting from a toxic partner, has come to believe he can only enjoy relationships that hurt. But Juhwan sees right through him, and offers something different—something kind.

"I’m used to getting hurt. My partner likes it that way."
"Then try it with me as well."
"I’m not talking about pain. I mean something real—something gentle."

With Juhwan’s quiet patience and unwavering honesty, Yeonsoo begins to realize that love doesn’t have to come with bruises. And maybe, just maybe, he deserves something softer.
