This omnibus adolescent drama is about a group of young girls who all attend a girls-only musical school, recounting the formative years they shared, at times shifting between different characters' viewpoints and time. Awajima Musical School Training Camp, dubbed the boarding house, is where young girls gather from all over Japan to perform on stage. Tabata Wakana aspires to be a musical star; housemaster Takehara Kinue attends to carry on her best friend's wishes; beautiful Okabe Emi is a scholarship student who is always at the center of attention; and Ibuki Katsurako, who became a teacher at the school though originally from a family of actresses. The unique environment of the musical school is simultaneously a respite space for these aspiring girls and also a harsh battleground that pits young students against each other. It is a place where perseverance can lead to blossoming talents, but also to a cruel reality at times. The clear depiction and psychological portrayal allow the subtle inner workings of each character to come through. (Source: Japan Media Arts Festival, edited)

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.
