The hustle and bustle of the big city. Sumire Yaotome, a student at a music school in a major metropolis, decided one day that she just had to get away from it all, and vowed to transfer to a school outside the city. She made her way to Nagano Prefecture, finding herself amongst the resorts and vacation homes that lined the picturesque streets, and by chance, found herself at Cafe Primrose. She could hear the faint sounds of instruments being played, and could smell just a hint of coffee in the air.But this pleasant little cafe and its relaxed atmosphere held a little secret. It was about to go bankrupt.

"Sumire, please, help me save our cafe!"

The little voice that called out to Sumire for help was Momo Momose, the diligent young girl who ran the cafe. Here begins our youthful story, of friends working to breathe new life into their beloved cafe, through music.
