Kenji Tomosaka moves to a coastal town as a child. The sea spread in front of him shines like ramune, reflecting the sunlight of the summer. He meets Nanami Konoe, who lives next door. As time passes, their shared memories have accumulated. They think of their normal lives and relationship as precious things. The sun begins to shine strongly, cicadas begin to buzz, and the sky clears up. For Kenji and Nanami, it is not just another ordinary summer.
