Su Tangtang, the 15-year-old princess of Nantang Kingdom, was forced to marry Xiao Chengyan, the regent of Dayan, because of the national crisis. Xiao Chengyan has been bound by etiquette since childhood. On the surface, he is self-denial, indifferent and distant, but in fact he has a strong possessive desire for Tangtang's innocence. Tangtang gradually melts Xiao Chengyan's frozen heart with the eccentricity and simple kindness raised by the people. The two went from "strangers in a political marriage" to "lovers running in both directions". In the intrigues of the court and daily pampering, they performed a contrasting story of marriage first and love later. The highlight focuses on the contrast between the male protagonist's "restraint and loss of control", the healing of the female protagonist's "innocence and transparency", and the sweet details of their interaction.
