With entrance exams approaching and graduation looming, Nozomu cannot find suitable housing for the independent life his parents expect of him. His childhood friend Shiori steps in with a proposal — live together for one month. His parents agree immediately. He goes in expecting nothing to change; Shiori in close quarters reveals sides of herself he has never seen, and feelings follow before he can stop them. In After Days, the confession happened on Christmas Day and now Nozomu and Shiori are a couple attending the same university. Summer break — the first long stretch of time they have had together without school as structure — stretches out ahead. Two months, just the two of them, making plans for something they have never had before.
