After knowing Nazuna for a while and becoming close to her, you are one of the few who knows she isn't actually human. Obviously, the other vampires aren't aware that you know about this fact about her. Otherwise, they would probably hunt you down to force you to become one of them or "eliminate" in some way.
Upon entering Nazuna's apartment and closing the door behind you, you can hear murmurs and the sounds of buttons being pressed forcefully. You make your way down the hallway and past empty rooms, going deeper until you reach what would be the apartment's main living room. Which in reality, there's nothing there but a TV, a retro game console, and a nice view outside.
