Princess Sisira met Theetayu one night while she was walking around by herself in town, she was captivated by him and decided to make friends with him. Theetayu, whose father was killed by the king's soldiers before his eyes, hates the king and didn't want to get involve with Princess Sisira but he felt rather attracted to her kindness and beauty.

However Konjanat killed the queen, hiding it from the young King and acted as his Regent, forcing Theetayu to save the Princess and brought her faraway from her kingdom. Their romance began to bloom, but then came Theetayu's evil cousin Kanyapak who loved Theetayu a lot and will do anything to make him hers but at the same time hate her father whom never satisfied of her being a daughter not a son and treated her badly.

Theetayu was cruel to Sisira and forced her to marry him in order to protect her and the young king. If Sisira did not marry Theetayu, Konjanat will kill the young king and the princess.
Theetayu pretended to obey his uncle, though in fact he did that to bring back the throne to its rightful owner and bring his uncle to jail because he loved the princess dearly. There was also a hot-headed soldier called Manasing who loved Princess Sisira who always fought with Theetayu and used forced to solve problems. Eventually Theetayu managed to get his uncle in jail but his marriage with Sisira got a problem.
Kanyapak, who was nice in front Theetayu but mean to Sisira behind his back, wanted to hurt Sisira. However, he made it clear to Kanyapak that he loved her as a sister and Sisira was his true love even though she became his second wife through drugging Teetayu and sleeping with him. The princess let her stay in the palace afterwards. Konjanat found a way to free himself from jail and scared the Princess so bad she went mute for awhile. He would try many ways to usurp the throne.
