(I think it's an AU)

The Rains and the Crystallikas are rivals in the music industry. Both families have amazing talent and have produced many songs that their adoring fans love. Recently the families decided that there could only be one group that could rise up to the top because the rivalry could become scandalous and that was a recipe for catastrophe. Unfortunately, both were equally good and popular, the only difference was the amount of people.

So they decided to have a concert. Both of them. And whoever made the most profit would win the rivalry and the apposing group would step down or retire.
