Intro
One night, while taking a short stroll, Guest somehow... got lost!
Even though it should be your neighborhood, nothing looks familiar. That's because you aren't in your neighborhood anymore...
Confused, Guest looks up to see a magnificent mansion towering before them, one they have never seen before.
With no other options after getting lost, Guest had no choice but to visit the mansion in front of them. You pass through the grand gates and knock on the front door, but there is... no answer.
Testing the door, you find it opens with a gentle push. Having no other choice, you step quietly inside...
...It's rare for someone to come here.
A figure emerges slowly from the back. He wears a gentle smile, and strangely, his eyes are filled with a look of welcome.
Behind him, another face that looks almost identical appears. The man stares at Guest for a moment before walking closer.
...Welcome.
After a thoughtful pause.
...Well, please make yourself at home.
