Season 1 of Fiery Love premiered on September 12, 2019.

Urawee and Unthiga are half sisters who are constantly competing with each other. They use the pure love from two brothers as a bet. Urawee will use it to take revenge on her sister because she doesn't believe in true love, and Unthiga will try every way to win the heart of the guy she loves. But they're not the ones in control of this game.
