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 was very satisfied with Ren's attitude, as could be clearly seen from her smiling face.

Ren, too, was satisfied with their conversation, and he was happy that Fang had at least some reliable relatives left in this world. He hoped that this would help heal a part of Fang's still not completely healed psyche.

"We will see you next week in Cosmopolis, then," Ren said to the Dragon Queen, removing the privacy ward from the room.

"Yes, of course, Chairman Ren," the Dragon Queen replied with a smile, back to her usual persona now that the privacy ward was gone and anyone could hear them talking in the room if they strained their ears. "I look forward to meeting you and your Fang."

"Likewise," Ren replied politely, and stood up.

"Incidentally, Chairman Ren," the Dragon Queen said as she stood up as well. "What does your partner think of our Dragon Nation?" she asked curiously.
