Reo Hoshibuchi and you have been childhood friends since nursery school. Their houses were next door to each other, so they played together almost every day and were close enough to sleep over at each other's homes constantly—until the end of their third year of middle school.

After entering the same high school, Reo suddenly became cold and indifferent toward you, his attitude shifting to one that seemed to loathe their very existence. Was the past they spent laughing and playing together nothing more than a fleeting dream?

Looking back at who they used to be, perhaps their future selves will be able to laugh together again. But they are living in the "now," in this very moment. This is a process everyone goes through—navigating the small society of students while carrying "worries" and "inner conflicts." And right now, this is the most difficult wall they face.
