But, said ruler who took care of him also fell in love with her. He planned to kill Jayaprana so he could be together with Layonsari. He arranged for Jayaprana to lead a fight with pirates that invaded Bali's northwest. Long story short, Jayaprana got killed.
When the ruler asked for Layonsari's hand in marriage, she declined. She chose to stay loyal to her dead husband. She then killed herself rather than being forced to marry him.
However, in Aruna and Damar's case – unlike her counterpart in legend – Aruna was blinded by the ruler. She forgot his very existence. She forgot how they were always together, inseparable.
They used to run around together, crying in each other's arms, he even taught her how to make her own happiness. If there was Damar, then Aruna must have been by his side, grumbling. If there was Aruna, then Damar also must have been by her side, throwing absurd words for anyone who might listen.
