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

Wade actually did turn up with Fang after a few days, when the latter came to pick up Ren from work. Ren shot Fang an enquiring glance, and Fang shrugged helplessly.

Wade also brought a basket of goodies for the babies - he'd carefully bought them under Fang's guidance.

The three furballs, who were stretched out on Ren's desk as he put away his papers, eyed Wade warily.

"I was rude the other day and didn't greet my niece and nephews properly," Wade said softly and bowed in apology. "I brought some treats today."

"Thanks," Ren said. He rubbed the three little heads on his desk and told them, "This is my younger brother, Wade."

Snow, Smoke and Shadow sat up and fixed their round eyes on Wade, but didn't call him uncle - in any case, Wade didn't have magic, so he wouldn't know either way.

"May I...touch them?" Wade asked hesitantly.

No way! The three fur babies were united in their decision.
