Series by 池山田剛

Azumi has harbored a secret crush on her childhood friend Yūhi since they were kids, but their promise to attend the same high school is thrown into doubt when Yūhi is scouted by a prestigious boys' school's track team. As they navigate the challenges of growing up and the distance between them, Azumi finds herself caught between her feelings for Yūhi and the attention of two other boys: Masaharu, Yūhi's charming rival, and Haruomi, a mysterious transfer student.

Rin Takanotsume, a soccer-obsessed high school boy, is thrown into chaos when his father's remarriage suddenly brings three adorable but quirky step-sisters into his life. The lively and popular Rio, the cool and reserved Yone, and the sweet youngest, Yume, turn Rin's once-simple routine into a whirlwind of surprises. At school, Rin is surrounded by even more unique girls: his childhood friend Shimayu, the soccer club manager Senpai, and the class president Kawamai. As the Takanotsume household navigates the ups and downs of their new family dynamic, Rin finds himself at the center of a lively and unpredictable love comedy.

Kokoro, a boisterous and carefree high school girl who sees all boys as friends rather than romantic prospects, experiences a dramatic shift when the handsome transfer student Chinatsu arrives, igniting her first taste of love and leading to tender moments of embraces and kisses; however, her hesitation to confess her deep feelings sets the stage for a fantastical journey where she must confront the chance to redo her fleeting youth, weaving a poignant tale of first love, regret, and the longing to seize a second chance at happiness with a touch of time-bending magic.
