Kenji and Nanami have been waiting their whole lives to say what they already know. The show doesn't force them together, it spends twelve episodes proving they've always been together, just in a language neither of them has learned how to speak yet. Everyone around them sees it first.
As a child, Kenji Tomosaka moves to a seaside town and meets Nanami Konoe, the girl who lives right next door. They have been close ever since. Everyone around them assumes they're already a couple, yet both seem content to exist in the space between friendship and romance, neither willing to take it further. The series moves between the present and flashbacks that reveal how their friendship grew so strong, and whatever happens between them seems to draw them closer rather than drive them apart. Now another summer is arriving, and for Kenji and Nanami it promises to be anything but ordinary. A gentle romantic drama told in a slice of life style.
