Maybe a Fake Gintama - Chapter 577: Command Owed to Oppression

Immediately after Gu Changge realized he had transgressed into a fantasy world, the world’s protagonist, and fortune’s chosen, vowed to take revenge on him. Envied by all, he not only has the female lead head over heels for him but he’s also treated as a distinguished guest wherever he goes. Fortunately, Gu Changge’s prestige and power are superior to everyone else’s, so shouldn’t it be easy to trample on a mere fortune’s chosen?

In the next life time, he would absolutely not become an author.
He would once again be cursed to the danger of crossing over into a book.
During the time when he broke free of his shell, what he first saw was just the handsome, handsome male lead that he had written.
During the time when the male lead was pinching the small soft flesh of his neck, it was also his first time hearing the male lead’s voice.

Pei Bufan: “…… meow?”
