My Arch-Nemesis Is Acting Strange

Summary

My arch-nemesis and I both suffer from highly specific, incredibly inconvenient disorders.

I have skin hunger, a physical condition that leaves me desperately touch-deprived. He has episodic amnesia, and when his memory wipes, I am the only person he remembers.

So, we made a deal. He said, "Let's partner up. I'll help ease your skin hunger, and you play along whenever my brain resets."

It sounded like a reasonable transaction. What I didn't expect was for his amnesiac self to genuinely believe I was his girlfriend.
