The gentle daughter-in-law of a minister refuses to marry a rough martial artist, and her younger brother wears a phoenix crown and red makeup and enters the palace for her sister. She originally wants to live a perfunctory life, but she and the cold-faced prince confront each other tit-for-tat and have a deep love for each other. Together they survive life and death in the court.
Purpose: Substitute marriage is not about making do, but about me sacrificing myself in exchange for a fate alongside you.
