The Third Rule of the Restricted Area Is the Name on the Back of My Neck.

"There are three rules in the restricted area: don't step on cracks, don't speak loudly, and don't stay for more than three days. I committed all of them - and then I was bound to a symbiotic curse with the A-level deconstructor. If she dies, I will die, but I have ten years of experience in exploiting Party A's loopholes."
