Dual physics department, Qiao Zhiyuan ended up fighting with his mortal enemy in his previous life.
Until the day of the funeral, the treasured diary dragged her into the abyss. The diary expressed countless times what the junior student under the obedient mask did to chase her. And protection from mortal enemies to death.
With endless regrets and the love letter that Qi Liunian had not handed over, she lost consciousness, and when she opened her eyes again, she returned to the day before the tragedy happened. This time, she would protect him.
When his junior classmate offered the bait of "Qiao Zhiyuan's competition results and his mother's illness", leading Qi Liunian to the convenience store where he worked - a small alley without street lights, the guardianship that spanned two lives finally ushered in the final showdown. Can she use her past life memories and current life plans to completely tear apart her apprentice's mask? How will the secret of rebirth she hides in her heart be revealed with the trust of fighting side by side and the thoughts of her mortal enemy?
This is not only a rebirth and reversal about redemption and protection, but also a story of two proud souls, from "dead enemies" to "difficult to reconcile", and finally join hands to fight against the darkness and run in both directions.
