On the very first day Su Jing was pulled into the "Mirror Realm," she was told its five ironclad rules.
The fourth was: Kill your mirror image, or you won't survive.
She thought she was the hunter.
Until, in the first instance, she met that woman--
A woman with the same abilities and fragments of the same memories, even the same scars.
A woman who was gentle and warm in front of everyone, yet whispered in her ear, "I've been waiting for you for a long time."
A woman who was supposed to be her mirror image, yet kept pushing her out of harm's way at the brink of death.
"Su Jing, have you ever wondered why the Mirror Realm wants us to kill each other?"
What she didn't know was that the answer to this question would change everything.
Theme: In the Mirror Realm, the most dangerous thing has never been the trials. It's trust.
