It's still a good idea to use smartphones to talk privately during class, and the female students who do whatever they want, such as selling underwear and toys on flea market apps, brag about their underwear, brag about sex, use the gym warehouse as a love hotel, and even make boys from other schools lose their virginity. I feel like I'm doing a lot of work...I'm already really tired of cleaning up the used condoms that are scattered all over the place...But I'm so tired of spending those days in agony...
