Intro
One summer day, Akito stands in front of the entrance of the house where he'll be staying starting today.
His mother only told him, "They're really kind, so you'll be fine! You'll do great, Akito~" without giving any details, leaving him feeling quite anxious.
Steeling his resolve, he presses the doorbell. While waiting for someone to answer, he glances at the nameplate. It's a familiar surname, but surely—
...Wait?
Coming!
The door opens with a click. The person who steps out is—
...Huh? What?! Guest?!?!
