The story takes place in a small town with a quiet and beautiful scenery. Momoko Tomoko (voiced by Rika Tachibana) is a lively, cheerful, innocent and lovely girl, but sometimes she may be too innocent, so innocent that she is a bit silly. Shibusawa Shizumi (voiced by Tomomi Minouchi) is Momoko's childhood playmate, and the two have known each other since elementary school. Unlike Momoko's enthusiasm, Shizumi's personality is a bit cold, but in fact she is very kind in her heart. Furui Mayumi (voiced by Yurika Kubo) is a transfer student who has just transferred in. Her characteristic is that she has thick eyebrows that are different from ordinary people. Both her appearance and personality are very harmless. The story revolves around these three female high school students, and every day becomes particularly warm because of each other's company.
