A is a prodigious pianist, and that is what they are known for. The world expects A to become a world class soloist. The world has already laid out this path before them, but A doesn't know if they'll truly be happy in music performance.

B is a former pianist, who quit after developing a slow-growing weakness in their limbs. They must be wheeled around, but their musical passion still lives on in their piano compositions. Despite their fame as a composer, they still long for the old days when their fingers had the strength to play piano. B doesn't find the same spark in writing music as they find when they're on stage, showing off to an audience.

A and B end up working together/going to school together. They both know each other from their reputations.

Our characters go to the same music university.

• A suddenly loses the funds to attend school, and needs to put together enough money to make it through each semester. B wants to help them, despite having issues of their own to deal with at the same time.
• A and B have been rivals since they were young. As they compete for soloist spots and first chair, they also need to find joy in the playing of music instead of just competition.
• Anything else you'd like to suggest in this universe.
