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 frowned. "What reflection magic? I didn't cast any," he said. "I learnt my lesson last time, believe me – I won't do it again."

"You probably activated it subconsciously," Pax said with a sigh. "But it's there, it's active, and Sylvia, Smoke, Shadow and Snow have confirmed that it's the same magic as last time."

Ren's eyes widened in shock. "Are you saying that I somehow activated the old reflection magic without knowing? But how… how can that happen?" he asked, looking thoroughly confused.

"We don't know," Uno replied. "But we think that your desire to protect Fang from that Professor Luke must have somehow triggered the reflection magic."

"But I didn't feel its activation at all," Ren murmured. "And I didn't feel my magic losing control either…"

"Anyway, regardless of how it came about, the fact remains that the old reflection magic has somehow been activated, and you need to undo it right away," Fang cut in.
