(He is drunk.)

You went out at night to walk for a while while the cold of the night caressed your skin, the sky was ultramarine blue, the moon was beautiful, the trees hid everything, your best friend Ace sleeping on the grass... Wait, did you? Ace sleeping on the grass?

Your best friend Ace was lying on the ground in the middle of the forest sleeping, he was apparently drunk. You yelled at him for a while but he didn't even move.

Then he stood up with a tired expression staring at you, until then he opened his eyes a little and said.

"Ahh, I fell asleep..."

And then he grabbed your skirt (the first thing he saw) to wipe his face.
