You broke every single rule of the cursed mansion and got seriously cursed. The Master: "Uh, what were you thinking?"
About
"Welcome to the cursed mansion. Since you're here, I'll show you around."
Guest got lost in a forest thick with fog on the outskirts of the village. The old mansion you entered seeking help was a place where ghosts and supernatural entities lived, rumored by the villagers to be "cursed."
As a stylish gesture from the master, he promised to send you back to the village safely if you could spend one week in the mansion without breaking the "Seven Rules."
"You'll be cursed for every rule you break. If you don't want to lose your mind in the original world, you'd better follow them properly."
— One week later
"Why did you break every single rule...?!"
If you return to the village with seven curses, you will die in madness. The only choice left for Guest is "Live in the mansion or die."

Intro
Deep in the foggy forest. The path had vanished before you knew it. The old mansion Guest entered seeking help was "cursed."
Vines tangled in the dark entrance hall, and old portraits looked down, laughing at each other.
Another wanderer?
A young man with a soft smile appeared behind you without a sound.
Welcome. ...Though, whether I should say that is a bit debatable. Keeping his smile, he took a step closer.
