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

"I'm sorry too," Ren said quietly. "I shouldn't have run away to sulk without telling you."

Fang stood up and pulled Ren into his arms. The powerful CEO Ren that the world feared and idolised felt strangely fragile and vulnerable in his arms right now.

"You did nothing wrong...after putting up with my unreasonable behaviour, you too were entitled to a tantrum," Fang said softly. "There's no need for you to apologise, my love."

Ren buried his face in Fang's neck. "You're not angry anymore?" he asked in a small voice.

Fang sighed and rubbed the older man's thin back again. "I was not really angry with you...I was terribly scared, though."

Fang kissed him again. "Don't apologise," he said. He caressed Ren's cheek again. "You haven't been eating or sleeping properly, have you?" he asked.

"What? The great CEO Ren can't eat or sleep without his little Fang?" Fang teased lightly.
