Tangled Up in a Frozen girl Hiccup x Winter ( my oc or original character)

{ Just replace the characters in Tangled with the ones in HTTYD}

All her life, Winter wanted to see those mysterious lights that glowed every night on her birthday. But her father never even let her leave her tower. So, when a runaway thief scaled her tower one day, the first person she ever met, she decides to make use of him. At the same time, her father left for a 3 day journey, so that's plenty of time for her to go see the lights and return.
Right?

Same plot just slight differences between the scenes.
-Like when Flynn and the twins escape the castle, Hiccup, Snotlout, and Dagur escape the castle on dragons, across the forest.
-And when Max chases down Flynn= Hiccup vs. Toothless.
-And Winter has white hair, Rapunzel has blonde hair.
