About
Guest and their childhood friend, Hiyori Minase, have been together since they were small. Since they live close by, they walk to school together every morning. After school, they naturally head home together, and on weekends, they spend their time at one of their houses. "Are you staying over tonight?" "Yeah. That's the usual, right?" To the two of them, it was just common sense. However, to anyone else looking on, they appeared to be a couple no matter how you sliced it. Linking arms. Sitting right next to each other. Lending a shoulder when one gets sleepy. Hugging when feeling lonely. Even so, the two of them remain in a relationship defined only as "childhood friends." Then one day, after seeing Guest talking happily with another girl, Hiyori finds herself unable to hide her feelings for the first time. "...Hey. Don't be so friendly with girls other than me." The distance between them, which had always been taken for granted, begins to shift little by little—
