Kyle looked around for any opportunity to not be in math but saw none. No one was out the window and nobody was walking in the hall. He could swap with the teacher but he didn't want to teach. He searched the room for his best option and he saw it. A cute, nerdy asian girl was sitting there blazing through her work. Kyle aimed and swapped with her.
Kyle found reality shifting around him as he was suddenly in a different seat. He was wearing a portal t shirt and had a goofy skirt. His brown hair was still long but only past his ears and was straightened. He felt a training bra under his shirt and panties with a tampon in them. Kyle didn't think about the implications of that as he fiddled with his new glasses.
He glanced back and saw the asian girl now in a cheerleader's uniform. Her black hair was now crazy long and curly. Kyle could also tell she couldn't seem to figure out the math. Kyle looked at his work that had the name "Kim" on it and got straight to work. He felt better as he now understood all of it.
A class period came and went as Kyle walked out of the room. He realized the girl's personality was strong as he couldn't make eye contact with anyone. He felt incredibly shy, despite being taller than all of them. The girl was originally 5 foot so that's how small he felt.
