When I woke up, I found myself in an unknown place and time, with amnesia In a different world where magic is based on music, I was picked up by a princess who is a first-class pianist and beautiful in appearance, and I was made the princess’s personal butler and a student at the magic school. I’m the princess’s butler and a student at the magic school, and I also have other duties… I’m constantly faced with a series of challenges, and all I can do is let out a sigh every day, but I manage somehow, with a cup of coffee in my hand.
