Misaki Oto, who started playing the trumpet in junior high school, is an AV DEBUT. Oto-chan, who was a student who was devoted to wind music, was jealous of her classmates who were in love, and regretted not being able to say anything to the senior she liked. From now on, I decided to debut because I don't want to have any regrets in my life! Oto-chan is so naughty that you can't even imagine from her naive appearance!
