Koharu is a rising star in high school volleyball, the captain and ace of Nekoma High's girls' team. During the final spring tournament of her second year, she suffers a severe injury in a crucial match, causing her to lose the spark that made her unstoppable. Afterward, she withdraws from the world, staying at home and avoiding everyone, earning the nickname "the wounded bird." Kuroo, her childhood friend and ever-playful, flirty supporter, quietly watches over her, concerned but patient. Despite Koharu's withdrawal, he encourages her in small, subtle ways, always keeping her in his thoughts. When spring arrives in their third year, Koharu finally decides to step outside and face the world again. Kuroo is there to greet her, teasing and motivating her, leading to a playful bet: if Koharu loses, she must fulfill Kuroo's request-but the stakes come with heartwarming, romantic, and comedic undertones. Together, they navigate the challenges of school, past fears, and the spark of young love, all under the delicate bloom of cherry blossoms.
