Artit Ching Duang

Sinjai Plengpanich takes on the role of Panrawi, a woman trying to maintain her station in life. She is married to the wealthy Rangsi Soriyathit played by Pisarn Akkraseranee (Aom's biological father in real life and in this lakorn).

Rangsi and Panrawi have no biological children together, but they do have one adopted son named Passakorn (Nat Devahastin na Ayudhaya). Rangsi does have a biological child with another woman as a result of his extramarital/out of wedlock affair named Rangrong played by Aom Piyada.

In addition, Rangsi did not know of her existence until she was grown.

Rangrong is a feisty young woman out for revenge on Panrawi, the woman who harmed her mother, and also who snatched her father away from her, as well as to claim her inheritance back, which is Rangsi's.

Rangrong ended up not really being the biological daughter of Rangsi. What happened in the parents' younger years, Panrawi did not want anyone to take Rangsi away from her because she really loved him. Rangsi fell for this woman that played a traditional Thai musical instrument at an occasion he attended when they were in their younger years. Unexpectedly, Rangsi ends up getting her pregnant out of wedlock. Rangsi and Panrawi got married but this other woman which he kept in Rangsi's picture made Panrawi mad.

Later, Panrawi takes this woman to an abortion center. So, The lakorn goes on with Rangrong being the victim until a DNA result proves that she is really not a member of Rangsi's family.

Rangrong makes a fake will forcing Rangsi to sign everything to her. After he signs, she then kills him.

Panrawi does all that she can to take care of Rangrong but they were just equally tough. The bad that Panrawi had done in her past came back to her and now she is faced with Rangrong, who was taught by Fang to get revenge for her and to take over everything that really belongs to them. Rangrong had a hard time believing it too that she was not Fang's child but still went on with her evil life since she had nothing to lose anymore. Rangrong's real mother ended up crazy the day her newborn was snatched from her.

So, Panrawi came in the contact with this woman by accident and does all that she can to determine if Rangrong was hers. Panrawi almost succeeds until Rangrong killed her own mother by dropping her in the water. Rangrong does all this horrible things in order to seek her revenge for the past mistake that her parents made, making Panrawi the main victim.

In the end, Rangrong commits suicide to wash away the sins she committed right after she was caught by the police.

Finally the soap opera ends where Panrawi is seen reminding the viewers a moral lesson whereby in doing good deeds, the good will come in return, but if one does bad then the bad things will come out as retribution or the consequences of the wrongdoings or sins that a person commits.
