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

<p>Ren and Fang were not too surprised to hear the acceleration proposal from the professors – Ren's only concern was about Fang, because while Ren had been through medical school once already, this was child's play for him. For Fang, however, this was real education, and Ren didn't want to hurry him up unnecessarily. He was happy to wait for Fang however long he wanted.</p>

<p>Fang, on the other hand, wanted to finish medical school as soon as possible – part of it was because he wanted to stand by Ren's side as his equal and deserving partner, and partly because he was very worried that Ren might be actually getting bored in class because he already knew all these things – in fact, it was clear to everyone in class, be it the students or the teachers, that Ren knew more about medicines than a lot of experts they were being taught by, and these were some of the best internationally renowned experts!</p>
