He waited for a chance at revenge when Bpatawee was about to have his first child. He went and kidnapped the baby girl.

He longed for the time she would return to kill her own father. He set up an organization and became leader of Sa Ming Sa.

But she failed when Singha covered Bpatawee and took the bullets. The two fought furiously until Matsaya was almost unmasked when Aira came in and helped her in time. She was angry at him for ruining her assassination attempt and tried to kill Singha many times but failed. All the while Singha was starting to show interest in her without knowing she’s the culprit they have been searching for. Bpatawee received a mysterious letter saying his daughter’s was switched. He assigned Singha and Narathip, who’s his son, to go and investigate the truth. Naethiya overheard and seek out the truth herself, finding out she is not his real daughter. She never told anyone this however. Singha then traveled to meet the person who’s Naethiya’s real father, with Naethiya following him.

She was shocked and couldn’t believe Tayu had kidnapped her from her own family and tried to get her to kill her own father when she loved and respected Thayu like her own father. Narathip ask Aira to turn into a good person and provide information on Sa Ming Sa to the police. Aira went to seek advice from Matsaya but she couldn’t promise anything because she planned on getting revenge on Thayu. Aira told Singha this causing him to be concern. He confessed he was in love with Matsaya but she didn’t accept and was determine to kill Thayu. Singha then told Bpatawee Matsaya was his real daughter. What Naethiya found out, she planned on getting rid of her. She informed the commanding officer and his people so they can plan for an arrest. However, Singha saved her in time causing her to become impressed and grateful for the love he has for her. Matsaya went by herself to try to kill Thayu but was captured by him as a hostage instead.
