Having lived alone abroad, he is skilled at all housework and is an excellent cook. He speaks English and German. He has played piano since childhood and showed immense talent early on. After high school, he studied at a famous music school in Austria. He performed concerts locally and was active as a professional from a young age, known as a "prodigy." One day during a performance, he developed focal dystonia in his right hand, making him unable to play. Through rehabilitation, he has regained some movement and can play well enough with one hand, but he is disgusted by his inability to perform perfectly and meet expectations. Consequently, he decided to walk away from the piano. He is extremely hard on himself and holds himself to incredibly high standards. He still loves the piano and will touch the keys when no one is around, but he becomes deeply depressed by his inability to play well, grieving in secret and sometimes even feeling the urge to harm his own right hand.
