Love Hurts (Dean Ambrose and OC Fic)

Lucy Smith decides to take up boxing lessons with boxing trainer Dean Ambrose at his local gym "Unstable Workouts". Despite Lucy already being in a relationship (even though it's crummy), Lucy quickly develops feelings for Dean the more he trains her. Dean also falls for Lucy too, but is convinced she'll never like him. What happens when fate proves them wrong? Bad summary. Sorry
