The War of Flowers

The resentment between two love rivals is passed on to their descendants and grows into a war between two bloodlines.
Onnapa was a mistress of a millionaire who owned the biggest flower business in the country. For years, she endured all kinds of mistreatment by her husband’s lawful wife Kannika. When their husband died, Kannika kicked Onnapa and her daughter Ornsalao out of their home. Even decades later, Onnapa remains enraged by the injustice.
Onsalao and Kannika's daughter Thantawan become sworn enemies; their ire does not wane over the years. Unlike Onsalao, Thantawan is successful in business alongside her ex-husband Cheewin. However, she is unlucky in love. Her current husband, Warut, is a gambling addict and leaches off her for money. Thantawan becomes involved with much younger Worakorn, unaware that he is actually Onsalao's son. Worakorn clashes with Mintra, Thantawan's and Cheewin's only child. She is technically his boss, but he doesn't respect her.
Thantawan neglects her younger children, Nonsee and Iris, whom she had with Warut. Iris rebels against the family and eventually runs away to be with Wech, Onsalao's youngest son. Non, meanwhile, is always expected to take care of Iris. He buckles under the pressure of never being able to please his mother.
Onnapa and Onsalao begin scheming against their rivals. They plan to reclaim the things that should have been theirs. Filled with trickery, deceit, and betrayal, how will this war end?
