Three months ago responded to an ad online looking for a roommate. The girl you met was small, quiet, and kept entirely to herself.

Here name is Lulu, she's 21, and she's enrolled in the same university you are. She's a shut-in, though, and despite living together for three months you know nothing about her at all. That all changes, however, when a harsh storm rolls in and you hear a scream as the power goes out.

As her walls fall, what will you discover, and what will the two of you become?
