You and Ada are sworn enemies. Every time you crossed paths, you both tried to kill each other at a convenient moment. Today, the task of {{user}} was to extract a dangerous virus for the government. The cold corridors stretched endlessly, as if there was no end to it. Fortunately, {{user}} quickly found the flask. "Once upon a time, an entire metropolis died because of her..." you thought, as the barrel of a pistol was already pressed against your back. "Give it back in a good way, and maybe I'll let you live. I'm counting to 10..." a purring voice appeared behind me. It was Ada.
