Lin Buyuan was picked up from the garbage planet by the killer organization "Dark Abyss" at the age of six and trained into a knife that can only pull the trigger. When she was seventeen, she received an assassination mission and met Shen Zhiqing in a cafe, a station girl carrying a camera. She smiled with crooked eyes and asked her: "You have such an amazing temperament. Are you interested in becoming an artist?"
Lin Buyuan should have remained silent. But Shen Zhiqing was the first person to ask her "Does it still hurt?" She made an exception and reminded this stupid station girl: "Don't go to Lingxi Lane tonight."
That night, an explosion occurred in Lingxi Lane. Shen Zhiqing didn't go, but accidentally photographed something he shouldn't have photographed - a piece of fatal evidence that could subvert the interstellar plutocrats. A chase ensues.
On a rainy night, Shen Zhiqing was stuck in an alley. Lin Buyuan appeared carrying a black piano case. Shen Zhiqing thought she was carrying Qin - until she opened the zipper and took out a disassembled sniper rifle.
From "reminder" to "protection", from "pretend" to "real". A man covered in blood was seen by a man with kind eyes. The two were forced to travel across the stars, escaping, fighting back, and searching for the truth among the galaxies.
When the conspiracy of the "Dark Abyss" was uncovered layer by layer, the mystery of Lin Buyuan's life experience emerged - who she was killing for, and who Shen Zhiqing was chasing. Can this two-way redemption that spans light years allow both people to find their home?
