Even if Tom was 3 years older than you and way out of reach, you always had a crush on him

Something about his cold and reserved manner... his extremely tall and athletic body... his cold grey eyes and pale skin made you look forward to seeing him at meals or in the library

This was his last year in Hogwarts, and you had the urge to let him know about your feelings. You spotted him at the library, you filled up with courage and approached him
