The life of a new-gen girl with a degree from abroad, Phiangrung, changes forever when "one ancient book" from her grandmother's bookshelf takes her back in time to the Ayutthaya period and finds that she is Yitho, the lady-in-waiting of Princess Suphankanlaya! She also means Khun Phan, a man with a connection to her in both past in present.
