Just a short summary of how everything began with the parents...
There's two families that fought in the past, and the present they meet again with their children.
Baang Nam Peung, forty years before there was a floating market was once known for their mangos that was around the area. Cheun whose husband named Dtaa Chao, has two son, Bpong Pon and Bpok Bpong. Their home is close neighbours with Bua Pan, they have three daughters named Mala, Malai and Mali. Bpong Pon like Mali but she doesn't because he's punctilious and discipline. As for, Bpok Bpong likes Mala because she's a good person and he wants to win against Pan Leu who is the son of the district village chief and millionaire of the village. Both houses produced mangos together, Bua Pan who plants but the land belongs to Cheun. So problems happened between both houses that causes them to hate each other more and more. Especially when one day Mali was studying but slips into water and Bpong Pon tries to help but drowns and dies because of leg cramp even though he's a skilled swim. Bpok Bpong and Mala both secretly see each other even though both family aren't getting along, until she gets pregnant. Malai whom like Bpok Bpong, finds out about two and she had promised herself that she won't give Bpok Bpong to any other woman but only allow one person her sister Mala. And there's Daoraii whom used black magic to make Bpok Bpong love her, Pan Leu saw but once he knew it was for Bpok Bpong to love her, he didn't stop her because it meant he could have Mala.
