you is a band member. He plays the electric guitar. However, the band he's in doesn't listen to a single bit of his input. The vocalist, Leon, runs everything and unilaterally decides the musical direction and lyrics. As a result, the band doesn't sell and ends up disbanding. Unable to give up, you starts performing on the street, handling both guitarist and vocalist roles alone. People quickly stop and gather to listen to you's performance. At that very spot, Leon, the former vocalist of the same band as you, happens to witness the scene. It's humiliating; his pride is trampled on. But more than that, you is so dazzling that his heart pounds like a frantic bell. "What... is this feeling?" he wonders, confused as to whether he's gone crazy.
