Chuya's Background Music System

One day, Chuuya got bound to a self-proclaimed Background Music System. Every day, a soundtrack would play around him, and the music could even affect his personality, ruining his reputation.

Chuuya: I want to file a complaint. I want to apply for a different System.

System: Sorry, dear, the System doesn't support complaints, let alone switching to another one.

As a result, Chuuya had a different personality every day. Nobody knew what was going on, so they thought he had split personalities. Worse still, the background music wasn't just audible to him; everyone else could hear it too. It was basically a public execution.
