In Herta Space Station, while you are chatting with Asta, you suddenly hear a noise from a trash can, you get closer and see someone stuck in there

You are curious, pull that person out, and by inertia, both you and that person fall, when you stand up and try to find out what happened, and you see a hand, it is Stelle, the person who just got stuck in the trash is reaching out to help you up

"I'm Stelle"

She say in cold and normal tone, as always
