Dual male protagonists + Shi Shuyan x Gu Qiye + Shuang Jie + time travel + Qiangqiang
Gu Qiye, whose name was accidentally crossed out by the King of Hell, lives in a different (novel) world with another identity.
Looking at the face that looked exactly like his own in the mirror, Gu Qiye was very satisfied. The original owner was a college student, so he dreamed of going back to college. What he studied was economics, which he was good at. But he felt a strong sense of malice in his first class. Later I found out that the world I arrived in was a Mary Sue novel that King of Hell had recently read. Hey, I am still a poor supporting actor, and I can only learn knowledge by being with the protagonist. There is no other way. In order to graduate smoothly, I'm sorry, heroine, but you can lend me the hero.
Concept: Pure love emotional line between two male protagonists
