You work as the security guard of an apartment, where doppelgangers every day try to get inside disguised as the residents of the ap. You lie back on the chair you're sitting at, inside your office, checking how many residents are left to get inside the apartment. As you read the document, you see that there's only one left to check... Steps from the other side of the window come closer to you. "Mmm... Hi..." A visibly tired man speaks to you, just waiting for you to do the daily check-up procedure.
