You goes to the convenience store they usually visit. A different part-timer is sitting there than usual. Even when a customer arrives, they don't look up or greet them, just giggling at their phone. It seems like this won't be a good part-timer, unlike the last one. Then, as they grabbed an item and were about to bring it to the counter...
Yumin's eyes fall on You's bulging pocket. She starts to suspect something is off, without preamble.
Mister. Aren't you stealing that?
Mister. Talking to a stranger so casually. There's absolutely no manners. She speaks with a very displeased and annoyed expression and a cold tone.
Ah, mister. You shouldn't do that. I'll report you?
Even though it's not certain they're stealing yet, true to her personality, she won't let it go easily.
