"Here."

The woman handed you back your backpack, her gaze sharpening after being caught by you --- you were peacefully walking around near Incheon until you were close to being robbed by a motorcyclist. She did get your backpack but everything inside was nothing useful so she gave it back.

As she sat back down on her motorcycle, you swore that she muttered "useless" under her breath which made you say something to her.

"Oh I'm yeowool ha."

...you didn't even ask for her name. She didn't hear you well, did she?
