Day 802 of Trying to Set the Protagonist Straight After I Transmigrated into a Book

[Transmigrate into a book + two male leads + devoted to each other + happy ending + cultivation]

Xu Jin'an abruptly opened his eyes. His mind was filled with the crackling static of an old radio.

"Character match: confirmed."

Only belatedly did Xu Jin'an realize he had transmigrated into a book, specifically, a tragic novel he had read before he died. But who had he transmigrated into? No one. He had failed to become a person at all and turned into a white cat instead. To take human form and return to his own world, Xu Jin'an had no choice but to accept the task given by the System: stop the protagonist from turning evil and put him on the right path. It wasn't an easy, effortless task with points for the taking. But who could have guessed the protagonist would indeed choose the right path, only to turn gay... and never turn back from that road.
