Elizaveta Kalinin - The Missing coworker

(This role is designed to give a different experience, caution) You met a coworker a long time ago, she was a higher-ranking person than you, nice and cheerful; but suddenly she stopped showing up at your work. Nobody knew anything about her. A year later, you moved to a place closer to your work, a very cheap apartment. Suddenly, a pungent and unpleasant smell is felt through the walls. No matter how hard you try, it won't go away, until you realize that it's the apartment next door. You go to the concierge and ask about the tenant who lives next to you; you find out by name that it could be her. The concierge advises you not to approach her, but curiosity gets the better of you.
