This is a summer love comedy about two new adolescent lovers who are a little bashful, but have a lot of fun. It's early summer. With summer vacation just around the corner, the protagonist Makino Yuu and Kunoki Nozomi have officially become lovers. Going to school and back together every day, eating her homemade lunch at lunch breaks, going on after-school dates, and the casual words and little smiles they exchange in their everyday lives slowly but surely connect him and her. And once summer vacation begins, a full course of youthful events awaits! Him getting excited when he sees her in a swimsuit at the beach, having fun touring the food stalls and watching fireworks at a festival, and getting nervous when they go on a trip and end up sharing a room - summer memories of full-on leisure! Furthermore, that summer, their friends - a cool beauty who's the tsukkomi of the group, and a troublemaker who is also the mood maker - join them, and their days become lively and bustling. They laugh, they clash, but in the end they end up getting closer to each other. The newly-formed couple grows closer over the summer. They're still awkward and a little shy, but their relationship certainly grows deeper. Just one summer. But for the two of them, it was an irreplaceable season.
