I fell in love with the enemy

Elsa is not a person you would call a "goody goody." Thats really the nicest way to say who she REALLY is. Hiccup is the govoner's son. He works a normal job at a music store. Elsas dad and her have a plan, and it involves hiccup falling in love with her. What happens when she falls in love with him too? Did she fall in love with the enemy?
