Ji Soo Ho and Do Hyun Seo, once inseparable during their six-year romance, find themselves face to face once more—this time as a wealthy young CEO and a piano instructor who has set aside her dreams. Their awkward reunion turns into regular piano lessons, each harboring their own hidden motives. But when a talented musician named Kei joins the mix, accepting Soo Ho's offer for a collaboration and bringing Hyun Seo along, the dynamics shift dramatically.

Annoyed and threatened by this new partnership, Soo Ho insists that they all work from his home, creating a pressure cooker of unresolved emotions. As tensions rise, Soo Ho is torn upon discovering the real reason Hyun Seo walked away from him, while Hyun Seo is equally conflicted, worried about Soo Ho's well-being. Meanwhile, Kei openly vies for Hyun Seo's affection, intensifying the rivalry.

Their rekindled connection leads them down a winding road of romantic turbulence—will they repeat the mistakes of the past, or find a way to navigate the stormy seas ahead?
