Fakfah owns Baan Mook Lom Rak, a peaceful homestay resort, but her world is falling apart. She’s fighting to keep custody of her beloved nephew, Plawan, from his reckless father, Koltheep, and trying to protect her island from being taken over by the powerful Sirivaree Group for a luxury project.

Ayakut, the group’s carefree heir, runs from an arranged engagement and ends up on the island, only to be rescued by Takom—one of Fakfah’s people—whom he mistakenly attacks. Furious, Fakfah plans to hand him over to the police, but when Koltheep resurfaces with legal threats, her lawyer suggests a way to boost her standing: marriage.

Fakfah strikes a deal with Ayakut—marry her to avoid jail, and in return, help her case. He agrees, secretly planning to gather information for his family's business. But what begins as a marriage of convenience turns into something deeper.

As Fakfah fights for her nephew and her home, will love get in the way—or give her the strength to win it all?
