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

After breakfast, Fang laid out a set of new casual clothes for Ren, and waited upon him like a royal attendant while Ren took his bath. Then he helped Ren get dressed with his own hands.

"I feel like a fatuous king," Ren complained, as Fang buttoned his shirt for him.

"Only half of that statement is correct," Fang said in a glib voice, stealing a kiss from his beloved birthday boy. "You are not fatuous, but you are my king."

"Says the prince with the bloodline of two royal families," Ren countered.

Fang laughed. "Well, with such formidable blood flowing through my veins, am I not in the best position to judge who is fit to be a king?" he asked. "And I have already adjudged that you are a king, my king, the king of my heart – and there's nothing you can do but to accept it graciously, Ren!"

Ren let out a merry laugh, and the sound felt like the sweetest music to Fang's ears.
