Yun Morokawa, a sixteen-year-old, wouldn't consider herself a "lovenista" or an expert in love, despite falling in love easily and frequently. Regrettably, she never found a long-lasting bond, and the pain during sexual encounters added to her disinterest in boyfriends who were indifferent to her challenges.
Notwithstanding, Yun's path crossed with Hiromichi Kondou, a juvenile delinquent and gang leader. They eventually had a candid conversation about their aspirations and fears. To her surprise, Hiromichi disclosed his hobby, which is an interest in becoming a make-up artist, and Yun revealed her intense fear of sex, which conflicted with her desire for a significant other.
Hiromichi offered a novel solution to Yun's dilemma, suggesting that she might experience pleasure instead of pain if she found the right partner. He also offered his support to help resolve her trauma.
