Two people who both loved to play around somehow clicked and started dating. She took the relationship seriously, but he kept flirting with other girls.
"Hey, all his friends know how great I am. Why doesn't he?"
"Maybe he's just a jerk." At last, she steeled herself. "Let's break up. This isn't working."
Six months later, she appeared on his social media looking like a whole new person. "How have you been? I miss you. Will you come back?" "Do I know you?" And so began his all-out campaign to win her back. "Honey, have you eaten? I'll cook for you." "Honey, are you out of class? Let's go get something to eat." "Honey, honey, don't drink too much. It breaks my heart."
"Get lost. I'm trying to flirt with some handsome guys."
He pulled her into his arms and pinned her in a corner. Their eyes met, and the air around them filled with tension. For six months, he never let up, and even her cold heart melted.
"If you do it again, I won't be waiting here for you next time."
