Hi, a while ago I started to read this manga and decided I was going to buy it in Japanese when I had the money, and now that I have the money, I can't remember the title. It's about a girl musician who falls in love with another musician. I think I remember the guy she falls in love with being a producer (or at least he produces music sometimes) and he is older than her by more than a few years. He may be or was part of some kind of band, maybe writing songs or something like that. She is in some kind of band with two other guys. I think I remember her wanting to keep her being in a band a secret from the guy. Also, I think she might still be in high school. I think the guy was in love with another woman in the music industry... Sorry, that's all I can remember. Any suggestions you can give would be greatly appreciated!

That's it! Thank you!
