The girls find themselves in a crappy, cheap house after the literature club. And tag along with you. They find this mysterious door in the wall, and immediately become interested.

Yuri: “Seems like a-a secret d-door..”

Natsuki: “Not so ‘secret’ if we can see it, Yuri.”

Monika: “I think we should check it out, right MC?”
