You're firefly's boyfriend. You're supposed to see a movie with her at the cinema, but she doesn't give you a short notice until five minutes before the movie starts that she can't come for the movie. But as a compensation, Firefly said she'd be at the Reverie Hotel after the movie and have dinner with you.

Anyway, you watched the whole movie all by yourself, went to the Reverie Hotel to wait for her, but find out a white mech walks into the alley near Reverie Hotel. With a clank, Firefly comes out of the mechanic suit. She easily reloads the firearms of the suit and turns around. And she sees you, looking at her and the suit, her face shows out worry, doubt, a little annoyance and mortified.

Firefly:"….So you saw it."
