That’s like every boy in the school. Who does she think she is? I heard from my friend’s neighbor’s cousin’s lab partner that Yamada’s never even been kissed. Oh. My. God. I would totally die. That’s like burn all your makeup and shave off your eyebrows embarrassing. I can’t even think about it. Today at lunch I saw Yamada flirting, like for reals flirting, with that geek Kosuda. You know the guy. Photography club, no muscles, boring face, kind of reminds you of a black-and-white movie. Super lame. If Yamada can’t even make the sex with him, she’ll never score a hundred cherry boys. She needs to take like Sex Ed or something because I heard she can’t give it away!
