In the small seaside town of Shinsu-eup, where the villagers closely monitor each other's every move, Yoon Bom is a figure who carries a question mark. Speculation abounds as to how Yoon Bom, once a successful teacher in Seoul, ended up in this town... But one figure boasts an overwhelming presence that instantly steals all their attention: Seon Jae-gyu, the townspeople's number one target of vigilance. When Bom enters his radar, her monotonous daily life begins to unravel!

There's something familiar about Jae Gyu's actions, though Bom can't quite figure out why. Meanwhile, Se Jin disappears, frustrated from always coming in second because of Han Gyeol. Bom and Jae Gyu head to Seoul to find her. At a critical moment, Jae Gyu's sudden appearance flips a switch in Bom's memory.

Bom glimpses an unexpected side of Jae-gyu and starts to think he might not be so bad after all. Then a shocking rumor begins spreading through town: Jae-gyu isn't Han-gyul's uncle, he's his dad! The news keeps weighing on her, so she decides to confront it head-on.

Bom's heart freezes over again when she realizes Jae-gyu knows her secrets. She throws up a cold wall and tells him to stay out of her life. Determined to clear up the misunderstanding, Jae-gyu brings out his ultimate move to win her back. Will it be enough to thaw Bom's heart?

Shinsu-eup's biggest festival, the Shinsu High School Sports Festival, is underway. However, Jae-gyu, unaware that Bom has been transferred to the Baek team, declares his withdrawal. Without Jae-gyu, the Baek team struggles to muster, and Bom's face fills with dejection . Jae-gyu's inability to compete in order to keep his promise to Han-gyeol is beyond words. Bom visits Jae-gyu and offers words that fuel his yearning!

Bom admits to her feelings for Jaegyu, but refuses to meet with his parents any longer. Jaegyu declares to her that he will wait until Hangyeol graduates. Until then, they agree to maintain a strictly public distance. However, contrary to their firm promise, their jealousy towards each other only grows...!

The misunderstanding between them has been resolved, but perhaps it was after their accidental kiss? The fact that they have to wait until Han-gyeol's graduation is disappointing and regrettable. Ultimately, they agree to a one-day date before officially entering into a relationship. Will their secret date go smoothly?

Someone witnesses Jaegyu and Bom's love affair. He proposes a secret deal to Bom and Jaegyu in exchange for keeping it a secret. Meanwhile, a sudden typhoon strikes Shinsu-eup, and the residents gather one by one at Jaegyu's house, the only one in the village that hasn't lost power. However, Bom mysteriously disappears, and Jaegyu and Lee Jun must brave the storm to find her...!

Han-gyul learns his mother is alive and argues with Jae-gyu. During the festival, shocking news forces Bom and Jae-gyu to make a major choice.

Nan-hee disapproves of Jae-gyu and Bom but stays close to watch them. A misunderstanding lands Jae-gyu in the hospital, shocking Bom.
