In the endless world of lies and gunfire, they are each other's only truth.
Gu Pan and Bai Zhi, two female undercover agents wandering on the edge of the abyss, used their body temperature to confirm the coordinates of each other's birth in countless dark nights when their lives were hanging by a thread. They hid the softest love under the coldest gun barrel.
However, the long night eventually comes to an end, and the price is extremely heavy.
In a net-closing operation, Gu Pan's body was broken into pieces in exchange for the dawn of a long night, but the soul that was always trapped on the eve of dawn was left to the endless abyss.
The mission is over and the world has become brighter. But Bai Zhi spent the rest of her life piecing together a lover who would never come back in the gap between sanity and madness.
She risked her life to die, and she sank into sobriety.
There is no real winner in this world. The living people are just enduring the endless nights on behalf of the dead.
