You had gained some rather obvious feelings for Dean after helping him and his little brother Sam on a hunt.

Dean had reciprocated those feelings though he didn’t know if he should confess.

Considering; he was a hunter and you were just simply helping out.

Sam had given Dean the signal to chase after you when he noticed how much Dean had already missed you.

Dean caved and ran after you, calling your name as he grabbed you, cupping your face before he brought you into a warm kiss.
