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

Professor Klaus had indeed made a breakthrough – and a very significant one at that!

Ren completely forgot about his aching body as he listened to Professor Klaus explain what he had found out, and Ren realised that they were very, very close to the final solution! There was only one last bit that they needed to figure out – and this was why Professor Klaus had sought out Ren. After all, the original proposal and research premise had come from Ren!

Ren listened carefully, reviewed the notes and the experiments that had been done so far, and then started discussing with Professor Klaus earnestly. The two of them discussed for well over two hours before coming up with three potential final steps – and then the whole research team got to work to test out all three.
