Since her days in the countryside, Aozora has been called a slut by locals because she seduced countless men. When she moved to Tokyo for university, on her first day, she was drawn to Matsumoto-kun, a fellow student. She vowed to stop being reckless and pursue a serious relationship with him. But old habits die hard. When invited to Tsukasa’s house with friends, Tsukasa teased her and suggested they buy more drinks. A mere backhanded compliment about her cuteness awakened Aozora’s inner slut. She switched to 'first-time' mode, luring Tsukasa to her place and asking him to make her a woman. Tsukasa fell into her trap, drained of semen in positions he’d never experienced, feeling she was better at sex than him. Not just Tsukasa—everyone around Aozora could easily sleep with her. While she was busy with others, her crush, Matsumoto-kun, started dating Mikey-san.
