Second season of Hanazakari no Kimitachi e.

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.

Oh, to be young and in love. Oh, to be wild and carefree. The springtime of life is intense, tumultuous, and at times, oh so confusing. Spring, summer, fall and winter—love blossoms in all seasons. (Source: Webtoon Entertainment)

To most people around Mizuki Ashiya, her sudden choice to move to Japan from the United States comes as a shock. Her sole reason for the transfer is to attend the same high school as her idol Izumi Sano, who stole her heart after she saw him compete in a high jump competition. However, there is one problem—Sano attends an all-boys school! That does not stop Mizuki, though, as she is committed to getting close to Sano by changing her appearance and demeanor. Mizuki luckily ends up in the same class and dormitory room as Sano, but her ideal plan is shattered when she finds out that he has quit high jump. Nevertheless, Mizuki is determined to learn more about him and rekindle his love for the sport, all while navigating her new life in high school and keeping her true gender hidden.
