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

The group made their way back to the imperial palace, and fortunately, there were not too many people who caught sight of them. By the time they reached the imperial palace and went to their rooms, Pax had already prepared the press release and sent the draft to Ren to review and finalise.

It was a fairly credible story of surrogacy that explained Ray's appearance and age. Ray was presented as Ren's biological child.

Since they were now back in the imperial palace of the Dragon Nation, Ren and Fang were able to take better pictures – well, of a better dressed Ray, anyway. After all, it wouldn't look nice if it looked like Ray was swathed in Fang's jacket, would it? The Dragon Queen had already made arrangements for a couple of sets of proper baby clothes which matched what Sylvia wore in her human baby form and some appropriate baby food (for both human babies and dragon babies).
