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

While Fang and Pax were busy making plans for Ren's birthday and setting up Zephyr, Ren and Wolf were busy investigating the seventh prince of the Valley Kingdom and what the man could possibly want with Fang.

"There really are records of the seventh prince going out of Valley Kingdom in the time period that man mentioned, Ren," Wolf said quietly, handing some papers over to Ren. "There is a good chance that the seventh prince actually came to Cosmopolis and went to the Orchid Orphanage and – and met Fang. The travel records are fudged up and buried, but we did manage to dig up some and gain some insider information as well…"

Ren cursed out loud, and a murderous aura rose up all around him like an almost physical thing.

Wolf, too, was no less incensed. If Ren said in this moment that he wanted to go to the Valley Kingdom and murder the seventh prince with his own hands, Wolf would go right along with him.
