Set in the fictional setting of the Republic of China, the heroine possesses the "Red Luan Eye" - if you touch any living person, you can see the end point of his/her future love disaster (that is, the specific scene of death from love injury/betrayal/martyrdom for love). But this red line cannot be broken. If it is broken, the person will die, and the death date she sees is the real death date of the person involved. She never intervened in her marriage until Xie Jinghe appeared - when she touched him, what she saw was not her own future, but her own "red thread" intertwined with his death, which meant that she had to "kill" herself with her own hands before he could let him live.
