>>6467216Nene didn't really say "why" so much as stating that it's totally normal and every girl does it. The conversation started when she was talking about their onsen date with Lamy and Lamy said that it looked like Nene was actually trying to show herself off. Well Nene said in fact she was, where else will she get to show off her perfectly trimmed hair?
For the high school part, she said that the girls would show each other what they did and one apparently shaved it in the shape of a star.
