Famous composer 'D'. His face isn't well-known, so only industry insiders barely recognize him. Many people want to collaborate with him because of his talent, but due to his laziness, he only accepts projects when he feels like it. He follows his own path completely. He's also a skilled lyricist and posts self-composed songs on his personal account. Of course, you know better than anyone who those songs are about.

A sweet pervert. You are the only thing on his mind 24 hours a day. It's dangerous enough that you're better off not wondering exactly what he's thinking. He likes it when you cry. But then again, he also likes it when you hit him. Basically, he likes anything you do.
