Lee Jeno is the prefect of Gryffindor ; he is smart, he looks good, likes to play quidditch and has been dating numerous girls ever since he arrived at hogwarts.

Na Jaemin, is his opposite. Prefect of Slytherin, he is indeed smart, but isn't into studying at all. He rarely plays quidditch and has to be dragged by his friends in order to watch a match. As for dating, he is a known player ; you meet him, you date him, he breaks your heart. The only detail missing, is that Jaemin is gay. And yes, boys should probably run away from him.

But how can you run away from someone who looks this angelic ? Even Jeno has a hard time keeping his eyes off the pretty boy (even though he would never admit it).
