   Summary

   Isagi narrowed his eyes at Rin, sighing exaggeratedly. “Anyways, you better not be a doppel-Rin saying all that shit about ooh, doppels are getting smarter, be careful! and inwardly cackling at the irony when I inevitably let you in. It’s insulting. And too meta.”

   “Meta?” Rin scrunched his nose. “Are you braindead? Also, doppel-Rin is the stupidest thing I’ve ever heard.”

   “I find it quite clever.”

   “Well, I don’t."

   “Well, I do.”

   OR: Itoshi Rin dies, and Isagi tries to move on... which is a lot easier said than done when Rin's stupid doppelganger keeps showing up. Why is he stalking him? Shouldn't doppel-Rin get the memo by now? Isagi isn't about to get tricked by a dead man! (Even if a part of him wants to.)

   ★ "That's Not My Neighbor" AU, featuring Doorman Isagi Yoichi and resident doppelganger Itoshi Rin.
