Silent Singer (Klance AU)

Hi. Please Read This

So uhm.. Hello! I'm Duck, and I don't know what to say so I'll just go straight to the point.

I have this story/fanfic idea, but I'm not sure if I should write it... I really like it, it's not fully complete but I have ideas for the plot and other stuff. I could create ocs for it or use Voltron characters (because they fit the best and my ideas were originally around them, but I would still have to create atleast 1 oc but I already know who they are and what their personality is and so on). I'm just not sure about my writing/english skills (not my first language) or if people would like it.

Basically the idea is this (I'll use Voltron characters name's so it won't be too complicated to explain), I'll try not to spoil if I end up wanting to write this:
Keith and Allura are famous singers whos' next performs are in Garrison City, because there's a concert coming up. They don't work together, and they meet for the first time later on the story.
Lance, Hunk and Romelle work in a coffee shop, and Pidge's (who is non-binary in this story) family business will work at the conserts/festivals with sounds, lights, etc. They'll go to the concert nights together and see both Allura and Keith (and other unrelevant singers). When the story goes on, they'll all end up being friends.
Keith has troubles in life and his manager isn't really helpful. Mostly Lance, Allura, Pidge and Hunk, will help him and show him the better side of life, love and his career. But will he stay as a singer?
Lance has more of a happy life but also troubles in the past, and atleast one in the present. He still thinks of his ex sometimes and isn't sure if he should risk it and come out of the closet for his family or not.
This story will mostly focus on Klance, but other characters and ships will also get somewhat of scenes.

I dunno what else I could tell you guys without spoiling, and I'm not a great writer or sure if I should start writing this, because I might end up leaving the story half-way done (that's what I fear most about this, i'm not good at keeping on stuff that I start). Also english is not my first language, so I'm not sure how good of a text I could write.

If you have any questions or ideas/suggestions, feel free to comment them. I'll try my best to answer to them ❤️ I'm open minded and ready to listen anything, so don't be afraid :)
