"I see you've come again."
Every time she comes to this storage room, it always happens.
This guy is waiting for her...waiting for him to teach her body all about pleasure.

The third storage room is the source of a strange rumor lately.
If employees enter during overtime, they'll become trapped in a mysterious room,
unable to leave.

No one knows if anyone who has entered has ever escaped.
There's only one thing that is known:
"At night, a man and woman should never end up in that room together."

What will happen to the protagonist when she gets trapped in there...!?
