The underappreciated prince of a vassal country meets the princess of the suzerain country who is despised by everyone. The man falls in love at first sight, but they conceal and deceive each other. A red thread that only the male and female protagonists can see tightly binds them. A sickly princess with martial arts skills? The mediocre prince is not mediocre either. A chance encounter at a sect conference allows the male protagonist to see that the heroine who was supposed to stay in the palace has now become a disciple of the sect elders and has a fiancé. What is going on? Everything around him seems ordinary but is actually dangerous everywhere. The red thread in his life is constantly being cut, and false marriages cannot be made. Everything will slowly surface after getting along and taking risks.
