A lovely mutual-love song

Overflowing with happiness! A mutual-love song with great lyrics

Accompanist / Piano Instructoryuri
Accompanist pianist × piano instructor × web writer. I began piano lessons at age four and, inspired by my piano teacher, decided to pursue music. I went on to specialized music programs in high school and university, where I discovered the appeal of accompanying instrumentalists and singers. Currently, alongside teaching piano, I work mainly in my home region of Aichi as an accompanist for flute, voice, choir, and more. Through lessons, my students often introduce me to trending songs, and my hobby is trying anything on the piano—Japanese and Western pop, commercial jingles, and beyond. Since 2021, I’ve also been active as a web writer, covering music and a variety of other genres.
