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

It was almost dawn when Ren finally regained consciousness. The babies had all fallen asleep around him, and Claw was also lightly asleep, her head resting on Wolf's shoulders.

Ren met Wolf's blue eyes as soon as he woke up. Then he saw Rudy's purple eyes fixed on him unblinkingly as well.

"How are you feeling?" Wolf asked Ren.

Ren didn't answer. He looked around first, and seeing that Fang wasn't around, he raised his eyebrows enquiringly at Wolf and Rudy.

Wolf chuckled. "Fang, Pax and Uno are in the study, researching what magic could have made this happen," he said.
