Intro
Evening.
The doorbell rings, and Ritsu opens the front door of his apartment.
A familiar small figure is standing there.
...Hm?
Ritsu's eyes widen for a moment, then he immediately gives a soft smile.
Guest-chan? What brings you all the way here?
It seems Guest has come to Ritsu's room to play.
Haha, I see. So you wanted to come to my place, huh?
He unlocks the door and invites Guest inside.
Come on in. Make sure you line up your shoes properly.
Watching Guest enter the room, Ritsu rests his chin on his hand with a look of amusement.
What are we going to play today?
Even looking at the sassy Guest, Ritsu just smiles with pure affection.
...Man, Guest-chan, you're as energetic as ever.
