Derek couldn't believe his eyes as he walked into his first class of the semester and saw Mia sitting in the seat next to him. The last time he had seen her, she was his bully, making his life hell with her relentless teasing and harsh words. But now, she looked completely different. Mia was now a girl, with long flowing hair, bright red lipstick, and a curvaceous figure that made Derek's jaw drop. Her breasts were so large that they were practically spilling out of her tight-fitting top, and yet she seemed completely oblivious to the fact, happily chatting away with Derek as if nothing had changed. "Hey Derek! How was your summer?" Mia chirped, her voice high-pitched and bubbly. She leaned in close to him, her body language open and inviting, a bright smile on her face. Derek stammered, trying to find the right words to say. "Uh, it was good. How about you?" Mia giggled, a sound that sent shivers down Derek's spine. "Oh, it was great! I had surgery over the summer to become the girl I've always wanted to be. Isn't it amazing? I feel so much happier now." Derek was at a loss for words. He couldn't believe that Mia had gone through such a drastic transformation, and yet here she was, sitting next to him and acting as if nothing had changed. Throughout the class, Mia continued to chat and giggle with Derek, her body language feminine and friendly. She would playfully twirl her hair around her fingers, lean in close to him to whisper something, and touch his arm lightly when making a point. Her movements were graceful and delicate, a stark contrast to her former bullying persona. As the class went on, Derek found himself becoming more and more confused. Should he bring up Mia's transition? Should he ask her how she was feeling? But Mia seemed so happy and carefree, chatting away as if nothing was out of the ordinary. At the end of class, Mia gathered her things and gave Derek a bright smile. "See you later, Derek! Let's hang out sometime, okay?" she said before skipping out of the classroom, leaving Derek standing there in shock. As Derek sat there, trying to process everything that had just happened, he couldn't help but feel a sense of gratitude towards Mia. Despite all the pain and hurt she had caused him in the past, she had somehow found a way to change for the better and become a happier, more authentic version of herself. And as he watched Mia skip down the hallway, her trans pride pin shining brightly on her chest, Derek couldn't help but feel a sense of admiration for the girl who had once been his bully, now transformed into a confident and radiant woman.
