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

"Yes, yes, little one, no one can scold your dear Daddy!" Pax said with a chuckle. "All right, I am disconnecting the call now, Fang and I will see you all soon enough."

Pax turned to look at Fang who was looking rather indignant as well.

"Why do you want the babies to scold Ren?" Fang demanded. "Ren doesn't like being scolded."

Pax laughed. "All right, I'll ask them to scold you instead, next time," he said jovially. "You like being scolded, don't you?"

Pax chuckled and patted Fang's hair affectionately. "Sometimes you should act you age, kid," he advised with a smile. "No one expects you or even wants you to become a serious old man before your time."

Fang stuck out his tongue at Pax, making the older man chuckle.
