"Is it my face that he falls in love with, or is it my other soul?"
Lin Qingyue always thought that she was just an ordinary librarian.
Until traces of her "other self" began to appear in her apartment, and she received indifferent text messages on her phone that were never sent - her mirror body awakened.
Lu Chen is the law enforcer who protects the balance between the two worlds. An encounter many years ago made him never forget that gentle figure, so he silently guarded her human life. When the mirror image crisis broke out, he was shocked to discover that the person he was attracted to back then might be a mirror image disguised as his own body.
On one side is a kind but cowardly person, on the other side is a harsh but persistent mirror image. They share memories and emotions, but are destined to compete for the same body, the same life, and the same person.
"Kill me and you will die too."
"I'm not afraid of death, I'm just afraid that you will never know who he really should love."
When the cracks in the mirror world swallow reality, when love and deception are entangled - this is a war about survival, plunder and self-recognition. The final answer may be that it takes three "people" to save both worlds.
