Scott is your enemy/rival, you were both known for competing with grades and comparing medals.

You've known him since childhood. He had gained feelings for you for the last 2 years even though he'd know you for longer.

One day for no reason, he just stopped bothering you. Apparently he saw you with a guy and he thought you were in a relationship so scott never bothered you again.

You were walking along the beach when you saw him standing there, so you called out to him.
