Ren, a modern doctor and a secret master magician, suddenly finds himself inside a random book he picked up at the airport...as the villainous older brother of the protagonist. As the bad guy, he's supposed to make life difficult for the Male Lead until the latter grows up and kills him in revenge. However, looking at the broken teenager in front of him, Ren can't help but feel his heart soften. 
Fang was an orphan who had never known what a family is. Abandoned at birth, all he knew was pain and fear. He loved nothing, and wanted nothing...until he saw the angelic Wade. To save Wade, Fang didn't hesitate to sacrifice himself. ..after all, there was no one to cry over him.
But then, Ren appeared and turned his world upside down.

The Villain Saves the Male Lead

Professor Luke seemed to have received a great shock at Fang's words. He fell silent for a long time, and then asked in a shaky voice, "What.. what do you mean…? Do you… are you… can you use both light magic and dark magic?"

"How is that possible?!" Professor Luke shouted. "How can light magic and dark magic coexist like this?!"

Ren, who had been fully awakened by now, frowned at the loud voice coming from Fang's phone. "If day and night, light and darkness, summer and winter, hot and cold – all of these things can coexist, then why can't light magic and dark magic coexist?" he said.

"Indeed," Fang said. "There's nothing wrong with light magic and dark magic being together, and there's no need to breed enmity where there isn't any."

"Well said, my big darling," Ren said, pressing a kiss to Fang's cheek.

Fang blushed and smiled, and forgot for a moment that there was a rather agitated Professor Luke still on the line.
