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

Ren sent a strand of his magic to the little golden dragon and the small creature lapped it up eagerly, and then blinked his golden eyes (which were, incidentally, rather similar to Ren's) innocently at Ren.

Ren's face took on a doting expression which everyone was familiar with by now, especially Fang.

Ren fed the little dragon another strand of magic and encouraged Fang to do so as well.

The little golden dragon looked at Fang lazily before accepting his magic. Then he shook himself and muttered, "I am supposed to be Papa's familiar, but I like Daddy more…"

Rudy immediately spoke up from Ren's phone. "No one likes Daddy more than me! Little dragon brother, why don't you be Papa's familiar instead?" he cajoled, clearly trying to weed out the competition even before the battle began.
