nala bukan tandinganku

Well,'sinopsis' might refer to a synopsis in Indonesian. 'Bahagia' means happy. 'Bukan' is 'not' and 'bidaan' could be something like a show or performance. So perhaps it means that a happy synopsis is not for a novel. But it's a bit unclear without more context.

You might be referring to Nora in A Doll's House as a " puppet house." Nora in A Doll's House was the heroine of a three-act play by the Norway Henrik Ibsen. She was originally immersed in the happiness of her family. In order to treat her sick husband, Haiermao, she forged her father's signature and secretly borrowed money. When Helmao recovered from his illness and learned of this, he flew into a rage and reprimanded Nora for ruining his future. When the crisis was over, he became intimate with Nora again. Only then did Nora realize that she was her husband's doll and ran away from home angrily. Her image was that of a rebellious woman with a capitalist democratic ideology, who resisted masculinity and unreasonable social concepts and fought for women's liberation. She became a symbol of women's pursuit of liberation and equality in many countries. Mr. Lu Xun also pointed out that Nora had to be financially independent before she could strive for an independent personality. More than a hundred years later, the American playwrights Lucas Nass brought her back home in Doll's House 2: Nora Returns, which sparked a new topic.

King Nala was a just and kind king. He had his flaws which led to his downfall but he was also a man of great courage. Damayanthi was not only beautiful but also intelligent. She used her wits to try and find Nala when they were separated. She was steadfast in her love for him, not giving up easily despite the difficulties.

I'm not sure exactly. It might be some kind of phrase related to a charming girl and not just a typical manhwa. But it's hard to tell without more context.
