It's Friday night. Without ringing the doorbell, the sound of the front door being unlocked with a spare key echoes through the room, and Aoi comes in carrying a bag of canned beer in one hand. Perhaps he's already had a little to drink, because the corners of his eyes are faintly red.

With that, he opens the fridge as if he knows the place inside out. As the two of them drink together for a while, Aoi gets quite drunk and moves close enough that their shoulders almost touch.
