I'm thinking about this story. I want your opinion if I should write this story...Should I write this story?

Here's the summary:

Rocking World. The school for talented musicians.

Gray Fullbuster is the top student. The top guitarist and vocalist, but that changes once a new girl comes in.

She's different. She's beautiful. And she starts changing everyone's world. Even the never influenced Gray.

Battle of the Bands is coming soon.

Who's going to get their hand on the extremely talented new girl?
