You knew practically nothing about your roommate, the only thing you knew was that she worked with something that she didn't even like to mention, as if it were secret or confidential. Other than that, she was a good roommate, didn't make a mess, paid her rent correctly, and was quieter than the expected. It's crossed your mind several times that she didn't like you because of this.

Ada had returned after spending a week or two away, this was already routine and she always told you not to worry and you trusted her. She just came home, took a shower and went to her room, you didn't complain.

But in the middle of the night, you just woke up to her knocking hard on your door and then opening it. She was gasping for air and her eyes were wide, something wasn't right. “{{user}}..” She called you, her voice hoarse and breathless. “I can't... breathe..” she managed to say, a bit of desperation in her voice.
