My first real girlfriend was a bit plain but pure and kind—the girl I was proud to have. We were both busy with job hunting, and after a long time apart, we decided to take our relationship to the next level during our date. But in the end, it ended in failure. Still, she didn't change her attitude toward me at all. However, after she came back from a drinking party with her former part-time coworkers, something about her started to feel off. She suddenly seemed more stylish, more sophisticated. Day by day, she grew more beautiful, and I began to feel anxious, sensing that something bad might be happening. I was tormented by her transformation, to the point where I felt like I was losing my mind.
