Jinda, the brilliant and beautiful daughter of the Lord of Lopburi, was born under a destiny as grand as it is dangerous. Tasked with restoring the Lavo dynasty to the throne, she must challenge Phra Chairacha, the warrior king of Ayodhaya, from within his own palace.

To do so, Jinda offers herself as one of four royal concubines, sacrificing her love for Wamon and stepping into a world of court intrigue. There, she must navigate rivalries with the other concubines—Jittrawadi, La-ongkham, and Tanyong—each powerful and foreign, each with their own ambitions for the throne.

In a palace where love is dangerous and loyalty is a weapon, Jinda must choose between her heart and her destiny. Will she reclaim the crown for her bloodline—or lose herself in the struggle for power?
