One is the daughter of a guilty minister, and she takes her younger sister as a slave in Yeting. One is the third prince with an awkward status, and all the stories between the two are like a narrated book. This drama is neither a palace fight nor a cliché, and there is no rebirth or system. He was just an unfavored prince, and she was at the bottom of the court, two marginalized people keeping each other warm. Later, when he became an emperor, she went from being a slave to someone who could stand alongside him.
