As a result, she had to raise her daughter Sompor alone. But years later, Thanachart learnt the truth and remorseful, went to look for his wife and daughter. However, he had an accident and died. After his death, Kamala, his mother and chairwoma of the Singkhabadirak Group, decided to look for her granddaughter, as she feels that her other granddaughter, Emika, Podjanee's daughter, is unfit to inherit the company.

As for Sompor, she never know who her father was. She finally decides to go to Bangkok to investigate and find her father. But she finds herself victim of murder attempts.
