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 Dragon Queen, Prince Uno, Princess Una and Zeus decided to travel with Ren, Fang and the babies in their private jet to the Dragon Nation. Their entourage went back the same way they had come.

The Dragon Nation was as pretty as ever, and the magic in the air was as rich as ever. Ren immediately felt recharged when he got out of the aircraft and breathed in the fresh air laden with magic. It was a small but amazing place, Ren thought, and now it was the place of his future in laws as well.

The babies were equally happy to be back – they had loved their last trip to the Dragon Nation. Also, they were magical beings, so the magic laden air of the Dragon Nation was especially nutritious for them.
