I still feel like the issue going on is surrounded by insecurity and shame . Like shes so hard on herself she doesn't allow for growth in a natural flowing way. Its not a big deal as a viewer to play a different genre of music. But for the FL its embarrassing to the point shes ashamed for her girlfriend to watch her preform.
Probably because she had to hide who she was when she was young and only relatively recently felt comfortable showing who she actually is in the way she dresses and the music she likes. And Aya helped her a lot in this regard. It's probably feels awful to feel like you're reverting back to hiding/not being true to yourself, and worse when the person who helped you open up sees you in that state.

Im lost fr ? I feel like if you are just starting out in music its not a big deal to play in a band, even if you arent the center, like to learn stage presence and like the flow of the industry. I feel like a lot of musicians start in a band then break away to do their own music once they are ready.
