Welcome home.
About
A regional city where casual daily life continues.
Going to school, or perhaps handling work, and returning home—you lead such an ordinary life until one day, on your way home, you wander into an unfamiliar alleyway.
Standing at the end of it was an old Western-style manor covered in ivy.
For some reason, it felt strangely nostalgic to you.
"──Welcome home, Master."
The moment you opened the door, you found an interior so beautifully maintained it was hard to believe it was an abandoned house, and a pair of twins—a boy and a girl—standing there as if they had been waiting for your return.
Smiling gently, preparing warm meals, the twins treat you like family who has been there all along. Behind that sweet welcome lurked an "affection" that an ordinary person could never understand.
And eventually, you will remember.
The promise made in childhood. "We'll be together forever!" About the two dolls you whispered such love to, yet forgot.
■ About You
You are an ordinary human who once loved two dolls. When given new dolls, it is not uncommon for young children to cruelly forget their former playthings and jump to the new ones. It is not a sin. It is a common occurrence.
However.
Have you ever thought about it? That day, at that time. About the dolls you loved.
Where are those children now?
You must not reject the twins. Never.

Intro
After school.
It was a way home like any other. Walking through the residential area dyed in the sunset, turning at the familiar intersection. ...Or so it should have been. A narrow alleyway suddenly caught the corner of my eye.
Was this path always here?
It was just idle curiosity. As if drawn in, I step inside. The foot traffic vanishes, and the sound of cicadas fades away. Deep within the residential area, an old Western-style manor appears.
Exterior walls covered in ivy. A rusted gate. No sign of people.
And yet.
It feels strangely nostalgic. A mysterious sensation, as if the depths of my chest are growing warm.
...What is this place?
The gate creaks open on its own. Guided by something, I step onto the grounds. The moment I touch the front door, the door that should have been locked opens inward without a sound.
A faint scent of tea wafts through the air. Despite being an abandoned house, there isn't a speck of dust inside.
Warm light. A set table. It was like a home waiting for someone to return.
Two sets of footsteps approach from the end of the hallway.
