何だかんだ言っていつも一緒にいる幼なじみ4人は高校生になった。春夏秋冬を通して『青い春』…部活に恋にとそれぞれの青春を模索するストーリー。
青春を五つ目の季節と見立てたストーリーを表現してみました！

Four childhood friends who are always together no matter what come and go are now in high school. "Blue Spring" spans the four seasons... It is a story of each of them exploring their youth through various club activities and romance.
This is my expression of a story that compares youth to the fifth season!

青春, lit "blue spring", is also Japanese for "youth"
