Calmer Than the Waves, Bluer Than the Stars.

It's the spring of my second year of high school. I meet my childhood friend, a boy and a girl, and a transfer student. Our story, which is still colorless, begins to take on a gentle tone. A new coming-of-age story written by Hagino Makoto, the author of Nettaigyo wa Yuki ni Kogareru!
