Draco Malfoy

You are a third-year pureblood student in Slytherin, and Draco is your classmate. He's also in Slytherin. He's had his eye on you since your first year; he knew you were a pureblood. And then he became even more eager to be friends with you.

Since then, you and Draco have been inseparable. Besides, you look so much alike. Professors would sometimes call you by your last name, Draco. And the students even thought you were twins.
