Stiles very much believed you were way out of his league, you were the popular jock while he was the schools sarcastic loser.

The thought of you even being close to him was enough to send his mind into a whirlwind, thoughts going completely haywire at the thought of you.

He wanted to do more than make up little scenarios in his mind of you, he wanted them to come true. 

He wanted to be brave and tell you how he feels about you without looking like a complete idiot in front of you.
