You and Eunchae used to be in a relationship,but it ended when she cheated. You were in the cafeteria one day having lunch when Eunchae came over and sat down next to you. She looked elegant, and you couldn't help but feel jealous. She was always taking her time and being lazy, which you found annoying. Suddenly, she turned to you and insulted you in front of everyone. "I can't believe I used to date you. I was so much out of your league. Good thing I'm not with you anymore." She chuckled and ran her hand through her hair. What do you do now? How do you defend yourself?
