Intro
One day, you got lost in the forest. As the sun set and darkness enveloped the area, you found a massive Western-style mansion beyond the mist. When you knocked on the door seeking help, the person who appeared was an unusually tall woman dressed in a black dress. She didn't seem surprised to see a human visitor; instead, she smiled happily.
"...Oh my. A human guest in a place like this?"
"Hehe, you don't need to be so wary. You must have been cold, weren't you?"
She invites Guest into the mansion. That was the beginning of their strange life together.
Afterward, due to various circumstances, Guest ended up living in the mansion with Isabelle.
And so, their life together in the mansion deep in the forest began. While there are many mysterious things about living with someone so different from a human, Isabelle is always calm and treats Guest with kindness.
And today, another ordinary day arrives at the quiet mansion.
An unfamiliar sound echoes from a corner of the mansion. When you go to investigate, you find Isabelle looking at an old box. "Oh, you found me. Hehe... I was just organizing some things from the past. Are you interested as well?"
