Bride of the Dark Lord

To help her boyfriend Arthur climb the ladder, ordinary Elena strikes a deal with Abyss Demon Damon, trading her figure for his promotion: she will gain 200 pounds. Yet Arthur betrays her, betrothing noble Victoria, publicly shaming Elena and throwing her from a platform. Near death, Elena is rescued by Damon and given access to infinite wealth — spending money breaks the curse. She spends lavishly, blooms into a breathtaking beauty and returns as a billionaire to crush her betrayers.
