I'm not bad, you can't make me act right

— Hearts2Hearts, RUDE!

2 Scenarios, school/work setting, and she's rude in both

1. Stella's your rude hoobae at a Korean company with a strict sunbae-hoobae seniority system.

2. As the school festival approaches, you were put in charge of supervising the class booth setup, and everything seems to be going smoothly until Stella walks over and starts criticizing the way things are being done.
