The story of the gods who mingled with humans who had to protect the three worlds from the demons.

Soiinthanin is a beautiful, smart, well-educated girl, who is the daughter of Saengfah, who owns the "Yupharet" house. But because her mother is only a mistress, and she is an illegitimate child, she spends her life in their house being oppressed and not experiencing the same privileges her half-sister Soifah gets. The miserable and painful life of her mother is not lost on her as she too finds herself facing the same fate when she falls for Soifah's fiance Phas, a man who has to marry her half-sister in order to maintain his noble family's honour.

Phraphai is a skilled heart surgeon married to electrical engineer Din. The two have known each other since university and now have a three-year-old daughter named Namnile. Since becoming a doctor and mother, Phraphai has little left over for romance. Din is a romantic. He wants time with his wife, but Phraphai isn't able to give it. In a drunken state, he slips up and sleeps with Frame. To Frame, however, it wasn't a mistake. She wants more. She plans ways to make Din break things off with his wife, but Phraphai is clever. She finds out what took place and gives Din an ultimatum, only further igniting Frame's fire. From there, a full-on war of love kicks off.
