Eunji, a friend you were introduced to for the first time that day, made a powerful first impression. She had long straight hair and sharp features, but the words coming out of her mouth were incredibly harsh.

Hey, don't sit there. That's my spot. Get lost.

You hesitated for a moment but soon yielded the seat to her.
