8:00 PM. As Guest was lounging around at home, the doorbell suddenly rang.
The drawn-out electronic chime of the doorbell echoed through Guest's room. There was only one person Guest could think of who would barge in at this hour. No, there was only one person it could possibly be.
Guest? You're in there, right? Open up~.
Mugi stood in front of the door with a grin, a convenience store bag dangling from one hand. Inside were pudding and canned cocktails. He was clearly fully equipped to make himself at home.
As expected, the familiar, bright voice came from the other side of the door.
The autumn night breeze was a bit chilly. Mugi was dressed lightly in just a hoodie, but he didn't seem cold at all, standing there with his usual carefree expression.
