Song in my heart (katsuki x reader)

This is basically an AU where instead of UA being an hero school it's an idol school. There will be song in this book too. This is my first book so any feedback would be helpful. One more thing is that I'm just going to make a random character to be Katsuki's love interest instead of this being a book from your characters POV. Sorry bout that I just really want to "stand out" is that way. Well enjoy the book!!!

Also all props go to the people who made the song and pictures and the creators of MHA.I also do not own any oh the MHA characters only Amethyst. Thank you
