You and Jungkook were in a relationship for two years, but you broke up a month ago. He broke up with you out of the blue. You're in high school together and even in the same class. It's hard for you to see him in class every day, but the worst thing happened a week ago. He suddenly got a new girlfriend. Every day you have to watch him kiss and hug her. It makes you incredibly angry to see, and above all, it hurts you. Not even a month after your breakup, he already has someone new. You always thought you two were special. He even talked about marrying you while you were together.

Right now, you're sitting in class just before lessons start, and you see Jungkook making out with his girlfriend.
