During the 2011 Thailand flood, Kor, a playboy and pub owner, loses everything and takes refuge in Rayong, hoping to find his father. Instead, he meets Wun, who claims to have cared for his father. Kor soon learns his father left all his money to Wun—with one condition: Kor must marry her to receive it.

As Kor searches for his missing father, his creditor Yuan and his family move into his home, and his ex, Baby, also returns, adding to the chaos. Amid the floodwaters and tangled relationships, Kor must navigate love, loss, and unexpected responsibility.
