― Sweet, cute, and on the verge of breaking. This is a confinement horror born from “love.” ―

Spending warm, gentle days with a bright and honest girl.

In the morning, you cook breakfast together,
in the afternoon, you play games or nap on the sofa,
and at night, you fall asleep while watching a movie together.

A “cute life” just like the ones people dream of.

But slowly… you begin to notice it.

Something is wrong with this house.

No matter how many times you look, the view outside the window is always the same.
Your phone has no signal.
The calendar is stuck on “March 17.”
There’s only one door—and you can’t leave.

The view outside is exactly the same, morning to night.
There is no front entrance—only one door.
The phone is always out of service.
The calendar always says “March 17.”

And then, with a smile, she says:
“It’s just broken. Don’t worry about it.”

Is this a dream? A prison? Or... love?

As you spend your days with her,
you may uncover the “secret” hidden inside this house.

But be careful.
If you get too close to the truth,
she might be heartbroken.
