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

"Don't you dare put yourself down!" Fang said fiercely. "My Ren is the best!"

Ren smiled slightly. "But, then, my dear, for me, my Fang is the best, you know?" he murmured in a gentle voice. "And can you imagine how I feel when my Fang is putting himself down?" he asked.

Fang froze. Did Ren feel sad and angry when Fang spoke of himself in bad terms, just like Fang felt sad and angry when Ren spoke so lowly about himself?

But if that were the truth, then wasn't Fang worrying over nothing at all and getting worked up and causing Ren to be sad and angry over an issue which didn't even exist?

Fang thought back to how Ren had swiftly cut off any chances of romantic hints every single time and declared his relationship with Fang immediately to everyone who dared to make a move…
