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

When Ren came to, he was in his own bed at home, with an anxious Fang sitting next to him and the three furballs clinging to him. Pax sat a little further away, his face dark and gloomy as he continued to type furiously on his laptop.

"You're up...?" Fang asked hoarsely as soon as he saw Ren's eyelids flutter open.

Ren felt a bit guilty at the sight of Fang's reddened eyes.

"Hey," he said softly. He tried to lift his arm and caress Fang's face, but found he couldn't move at all.

Ren frowned. "What happened?" he asked.

Pax came over. "You fainted in office three days ago," he told Ren. "There's seemingly nothing wrong with you, but you wouldn't wake up no matter what we tried. Fang and your fur babies have been worried out of their minds."

"Sorry," Ren said. "I don't know what's wrong...why can't I move?"

From the horrified looks on Pax and Fang's faces, Ren figured out that no one had expected that.

58 - What happened?
