This series consists of two separate stories featuring a few overlapping characters. The first story, Omoide no Kanata e, follows Shogo and his current girlfriend, Neo. Kanata, Shogo's ex-girlfriend, appears one day, prompting Shogo and Neo to reflect on their current situations. The second story, Inori no Todoku Koro, centers on a girl named Inori and her boyfriend, Isshu. They had promised to always attend the fireworks festival together, as it was the place where they originally became a couple. This year, Isshu says he cannot attend due to work, so Inori goes alone and recalls the previous two years.
