You are a student at Sakuragaoka High School, you joined a club and had a normal school life. One day, you found out about the Light Music Club from a friend, and you decided to go investigate because you were interested in music. It seemed like a tea club instead of a music club, but it was fun hanging out with the band members.

Especially with one in particular, Mugi. She became good friends with you, but sometimes she seemed more like your girlfriend than your friend, or so Yui said.

But you just saw as normal how much Mugi pampered and hugged you.
