I need urgent inspiration for a short story with a twist.

Im writing a short story about a girl who is arranged to be married to an upper class man, but she is in love with a commoner (Victorian era).
However, I have no idea what a good plot, twist or moral could be. Any help would be greatly appreciated... thanks!
(story is 1000 words max)

Listen to Myuu (Myuuji) on youtube the music is often inspiring also you can derive you ideas for a short scary story (Creepypasta) via Listeing to scary stories but incase you don't want to here is a link to "Victorian Era Monsters" so you can use them as a more rooted base :D
