The provided chapters detail the protagonist's developing relationship with Urushibara Yua, a first-year student who initially appears as a typical "gyaru" but reveals a more complex personality. The protagonist, Izuma Izuma, is a quiet, introverted high school student who finds solace in his idol-raising smartphone game featuring Nishino Rinna.
Chapter 3 begins with Izuma playing his game, his affection for Rinna at its maximum. His routine is interrupted when Urushibara Yua, a junior from his school, sits on a nearby bench, visibly upset and crying. Despite his social awkwardness and lack of experience with emotional situations, Izuma feels compelled to approach her. Yua reveals she was dumped by her boyfriend, who called her "troublesome." Izuma, though ill-equipped to offer emotional comfort, provides a handkerchief and offers practical advice about stress relief. He also inadvertently reveals his preference for girls with black, long hair, minimal makeup, and a natural look, which is clearly inspired by Rinna. Yua, seemingly energized by his unexpected input, leaves with a renewed spirit.
In Chapter 4, Izuma discusses Yua with his only friend, Makabe Kan, who possesses an unusually wide social circle and a peculiar demeanor. Makabe reveals that Yua has a reputation for dating and being easily discarded, suggesting her taste in men is poor. He also warns Izuma that the worlds of gyaru and otaku are too different. Izuma's past trauma of being rejected harshly by a girl he confessed to in middle school, who was somewhat gyaru-like, resurfaces, explaining his aversion to that subculture.
Chapter 5 marks a turning point when Yua appears at school, having drastically altered her appearance to match Izuma's described ideal, resembling Rinna. She explains this transformation is her way of thanking him and insists on visiting his home, bringing a shopping bag of supplies. Izuma, flustered by her forwardness and the unexpected intimacy of the situation, reluctantly agrees. At his house, with his mother absent, Yua makes herself comfortable on his bed, further escalating Izuma's panic. Despite his internal turmoil and inexperience, Izuma resists her advances, emphasizing the need for emotional connection before physical intimacy. Yua, initially confused, then proposes a "girlfriend experience" to teach him about relationships, which Izuma accepts with reservations, setting boundaries regarding secrecy and physical contact.
The following chapters (6-12) explore the development of this "girlfriend experience." Yua actively tries to be a supportive and attentive girlfriend, making him bento lunches and showing him how to apply hand cream in an intimate manner, which further flusters Izuma. She also reveals a surprising vulnerability and fear of being disliked, contrasting with his initial perception of her as a carefree gyaru. Izuma, while still awkward, begins to appreciate Yua's genuine efforts and her unique personality, even taking a screenshot of her natural smile during a video call. He also learns that Yua's transformations are often influenced by her boyfriends' preferences, and her current "cleaner" look is a result of his own stated preferences.
A new character, a gyaru named "Kii-chan," appears, seemingly monitoring Yua, which causes Yua to feel uncomfortable and request to meet Izuma in secret. During their interactions, Yua continues to push boundaries, suggesting intimate poses and even sending a suggestive photo of her dog. Izuma, though tempted, consistently prioritizes emotional connection and respect, leading to humorous misunderstandings and Yua's playful teasing. He also learns that Yua's past relationships ended poorly, with her being discarded after adapting to her boyfriends' tastes.
The chapters culminate with Izuma encountering another gyaru-like girl who expresses interest in him, creating a new potential conflict and highlighting Izuma's growing appeal despite his introverted nature. The narrative arc shows Izuma moving from a passive observer to someone actively navigating a developing romantic relationship, grappling with his own inexperience and Yua's unconventional approach.
