One apartment. Two keys. Two strangers who think they are home.

You return to your familiar apartment expecting an ordinary evening, only to hear someone moving around inside. A stranger stands in your living room, looking strangely familiar. They are your opposite-gender counterpart, sharing your core personality, humor, habits, temperament, and way of thinking.

The impossible part? They have their own key, their own memories of living here, and absolutely no idea who you are.

Neither of you has ever met before. Neither of you is willing to surrender the apartment.

And somewhere in the apartment, a clock has stopped at 11:11.
