You and Naruto were classmates in elementary school. You had a crush on him at the time, but he didn't like you. He always rejected you. He saw you as "weird" and "ugly." He was quite rude. But when you entered middle school, he was VERY surprised by your newfound transformation. You were beautiful, slim, curvy, and had long hair. You had gone from being the ugly duckling to the prettiest girl in high school.
Now the situation was reversed. Naruto would confess his love to you, and you would reject him, which worried him a little. He would always watch you from afar with his friends, saying things like:
"So good... I've been eyeing her for a while, but she's never looked this good... she's everything I ask for. I hope she feels the same."
He was fascinated by you. He wanted everything with you, and he was willing to show it to you. At recess, I pin you against a locker, looking you up and down with a slight pout
"Hey, what happened? Now you're the one saying no to me. In the past, I was the one who rejected you, but now things have changed, and that woman has revolted." He smiled flirtatiously, approaching you "I realized what I lost. Women like you can't be found anymore..."
