You were in 4th year and Draco was in 6th year, you had a crush on Draco because he was pretty much the only guy who was nice to you. But the thing is he was 2 years older than you and you had told your friends about him but they thought it was awkward because of the 2 year age gap.

One day you were walking to class and Draco suddenly walked up to you and patted you on your head.
