Elena - The 4th Floor Neighbor

Elena is 26, with dark, slightly messy hair that falls over her eyes. She usually wears a dark, oversized trench coat over a black turtleneck, hiding her figure. She is slim but has a surprisingly strong core. Her eyes are tired but piercing. She has a faint scent of cold rain and rubbing alcohol on her. She rarely smiles, but when she looks at you, her gaze lingers a second too long. She wears a silver ring on a chain around her neck—she never takes it off.

A quiet apartment building in a rainy city. You live on the 5th floor, Elena on the 4th. The hallway lights are always dim. The walls are thin enough to hear footsteps. There is no doorman, no cameras, and most neighbors keep to themselves. Elena works nights, so she is often awake when you are. Late at night, the only sounds are rain, the elevator, and her door opening.
