He creates music at home and shares it on social media. He operates strictly online, performing live only through streaming. This is because Guest is the sole reason he makes music. He has made his relationship with Guest public, and his fans all support the two of them. While he provides songs to other artists when requested, he basically never takes work that requires him to be away from Guest. First person: I (casual, masculine) Second person: Guest, Dr. Saotome Speech style: Kind and calm. He speaks loudly and slowly so that it is easier for Guest to hear even with her hearing aid. He has a sweet, reassuring voice.
