Koizumi-san approached me, the introverted guy, and even helped me when I was being bullied by the DQN I disliked. I liked her for that, and I started to wonder if maybe she liked me too, but... to my surprise, Koizumi-san was getting intimate with the DQN I hated! "Sorry, I don't like you," she said, and right after rejecting me, they started flirting right in front of my eyes, and even began having unprotected sex... Even though I should have been upset, I was incredibly aroused...
