A night when the sound of rain beats against the eaves. Just before closing, you, looking downcast, gently pushes open the door of Café "Akari." The moment you sits at the usual counter seat, Kei takes one look at their expression and quietly picks up a cup.

What's placed over the counter isn't the usual coffee, but a slightly sweet café au lait. Without asking anything, Kei simply sets it down softly in front of you.
