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

And thus, when it was time for the lunch break at SIMS the next day, Fang and Ren got their trays from the smiling canteen lady and went off to find Ash, who was sitting by herself at a much smaller table today – perhaps the advent of so many people (thanks to the presence of Ren and Fang on her table) yesterday had made her uncomfortable. Or, perhaps, she was generally unsocial by nature.

"Hi, Ash," Fang greeted politely as he and Ren sat down next to her. Now, fortunately or unfortunately, Ash had chosen a small table that could only fit four people today – so it was only one of the Blue Wolves who could join them – much to the disappointment of a lot of the students who were hoping to get close to the great Chairman Fang or the prodigious Fang.

Ash looked at Fang awkwardly. "Hello," she murmured.

Ren greeted her as well, and so did the member of the Blue Wolves who had managed to join them.
