On the surface, high school student Koyuki "Koyun" Hikawa seems unapproachable and terrifying to most other students. In reality, Koyun is just insecure and prone to overthinking due to her uncomfortable experiences in middle school. However, her chance encounter with two boys in school—Minato Amamiya and Youta Hino—sparks a change in her. Like her friend Miki Azumi, the boys are never afraid to approach Koyun and see her for who she really is.
Although Koyun starts spending more time with Miki, Minato, and Youta, she finds herself torn between her newfound bliss and her fear of getting too attached to others. Meanwhile, each of her friends quietly struggles with their own challenges. But as the new friend group continues to navigate high school together, Koyun and the others start to break out of their shells and enjoy their adolescence to the fullest.
As Koyuki slowly notices her new, surprising feelings towards Minato, first-year Momoka suddenly tries to cozy up to her — for reasons she can't grasp.
A spring break trip to the amusement park brings the four friends closer. Back at school, Koyuki's surprised by a familiar face — and Minato takes notice.
Koyuki mulls over the tense exchange in the infirmary. After Yota clears the air, she tries to have an honest conversation with Minato for the first time.
Stressful exams continue. Igarashi crosses paths with Ayumi during a joint school soccer practice. Koyun sees Igarashi and avoids him while reflecting on her painful middle school memories.
Bothered that Koyuki still has her guard up around him, Minato tries to make small talk. As Miki grows suspicious of his intentions, she confronts him.
