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>By the time the date for the school trip arrived, everyone involved was impatiently waiting for it to start. Steward Paul and Jules had flown in earlier that morning, and Fang was supposed to arrive with his schoolmates.</p>

<p>Ren went to the airport to pick up Fang. The three furballs, who had stayed with Ren this week, clung to him as soon as they learnt that he was going to pick up their Papa. Helpless against the triple attack of round, adorable eyes, Ren caved in and took them along. He made quite a sight - a handsome young man in a tailored business suit and three cute little furballs in his arms.</p>
