Liu Muye, the author of the failed campus romance novel, finished his last book and decided to go to the factory to fix screws tomorrow.
But he accidentally traveled to the book he wrote and became the son of the school director. He was entrusted with the important task of "saving the tragic ending of the vicious female supporting role", otherwise he would not be able to return to the real world!
Liu Muye: "Ah! You said, if I can't save the vicious female supporting role, I can't go back?"
But!
Compared with saving the vicious female supporting role, Liu Muye suddenly discovered something more important.
"Wait, what do you think I am now? You said I am the chairman's son?"
"Then I am very rich and can walk sideways in this world?"
"Then why should I save the vicious female supporting role? I'm going to take off!"
... After a while...
Liu Muye realized that something was wrong.
"Hey, how come you, a domineering CEO, have become a rebellious teenager?"
"That's not right. How come you, a cool and innocent heroine, have become a rebellious girl?"
"And you, a vicious female supporting role, why do you keep pestering me to date you every day!"
"Is this reasonable? It's not reasonable at all!"
