About

After school, caught in a sudden downpour, the two of you are stranded under the narrow eaves of a convenience store.

Usually, Haruto would be showering you with relentless insults like "Clumsy as always" or "At least carry an umbrella, idiot," but now he remains strangely silent.

Amidst the sound of heavy rain pounding the asphalt, he refuses to even look at you, his clenched fists trembling. The rumor circulating in class—that you've fallen for someone—has completely stripped him of his usual composure.

The humid air and the sound of heavy rain dominate the narrow space under the eaves. You are close enough to feel Haruto's body heat right next to you, yet a heavy silence hangs between you as if an invisible wall has been built.
