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

As predicted by Pax, the four bad men had been caught by the Blue Wolves within an hour. Wolf interrogated them personally, and then he rushed to Ren's home with his findings.

By then. Ren, Fang and Rudy had calmed down – although Rudy still clung to Ren, and Ren hugged the AI child in his arms without letting him go.

"Ah, little Rudy is here too," Wolf said as soon as he spotted the child. "You've done very well, nephew mine!" he praised.

His face turned serious as he looked at Ren, Fang and Pax. "These guys were truly well prepared – and it wasn't only the four of them. They have more accomplices, some within the school as well. That's why they were able to get in so easily and knew what classes the kids are in. Tom's leading a unit – we will get them all tonight, don't worry," he added the last part quickly, noticing the dangerous golden glow in Ren's eyes.

"Were you able to find out who the mastermind is?" Ren asked coldly.
