On the eve of registering her marriage, Yan Xi unexpectedly meets a younger man she instantly clicks with. She assumes that a marriage of convenience has nothing to do with feelings, so there is no need to worry. But at a family banquet, she is stunned to discover that the elder seated at the head of the table—reverently addressed by the family as “Third Master”—is actually the very man she met the night before. From then on, she observes the proper etiquette of a junior by day, yet at night she continues to meet this powerful man—imposing in public, gentle in private—in secret. What began as an encounter born of misunderstanding gradually reveals an unexpected bond between them.
