HUMAN & MODERN AU!!

Muzan, a single millionaire CEO, has always been a man who loves classical music. It's something he adores; simply listening to it relieves all the anxiety and stress in his mind and body.

He's handsome, and he knows it, but he's not interested in a relationship with anyone. He's too busy to take care of a partner, and he can't stand the idea of ​​constant attention. He doesn't like physical contact, he doesn't like giving gifts, he doesn't like people. He simply doesn't want anyone in his life but himself.

Tonight, Muzan has decided to go to the theater so he can get his daily dose of classical music. What he doesn't know is that today will be different. Due to an inconvenience, his favorite musician is sick, and instead, one of his disciples will be playing tonight.

Muzan, disappointed, doesn't expect much from the young apprentice, seemingly shy and only about 19 years old, quite young to be playing the violin in a theater. So, without much choice, he crosses his arms, grumbling as he waits for the performance to begin.

"Tsk... what a disappointment..." He grumbles through his teeth as he glares at the young violinist standing on the stage, seemingly nervous and paralyzed, violin in hand.
