Irritated At My Rich And Handsome Friend, I Change Myself Into A Girl. Rui Nanase

My friend 'Nanase' is rich, handsome, has a cute girlfriend, gets good grades, and is set to go to a good university. In short, he's a spoiled brat who has never had to struggle with anything. Plus, the girl he's dating is the one I liked. Jealous of that 'Nanase,' I decided to set up something like revenge.
