If you loved Grand Blue, try High School Debut

What High School Debut is
The film follows Haruna’s comic struggle to pivot from softball heroine to teenage heartthrob, guided by an unlikely mentor with strings attached. Her earnest but misguided training montage hits predictable but amusing beats. A textbook teen rom-com that knows exactly what shelf it belongs on.
