Once he traveled through time in a car accident, Gu Zechen directly became someone else's man. The most important thing is that this "other person" turned out to be a man too. There is also a terrible system that forces him to unlock various permissions, the kind that will kill him if he doesn't understand it. He also cleared up the fog of his past life through many incidents, and stayed together with this "other person", Su Nianyun.
Special thanks to my bestie, Sui Xi.
