Kally's Mashup Seasons

After Kally performs an original song that blends pop and classical music, the judges refuse to name her the winner because she presented a musical genre that is not allowed under the competition rules. However, they eventually decide in her favor, allowing Kally to keep her school scholarship and continue at Allegro, but things at the conservatory have changed a lot.

Kally is a young musical prodigy trying to balance her life as a piano virtuoso and a regular teenager when she moves from a small town to the most prestigious music school in the country.
