The Boys Over Flowers manga followed 16-year-old Tsukushi Makino, a bright girl from a middle-class family who gets accepted into the ultra elite Eitoku Academy. She finds herself on the bad side of the school’s F4, the four most elite male members at the school.
Kamio’s Boys Over Flowers Season 2 sequel manga debuted in Japan on Shueisha’s Shonen Jump+ website and app in February 2015, and ended in December 2022. VIZ Media published the manga as a free simultaneous digital release.

Congrats to Kamio! I’m not surprised, Boys Over Flowers is an iconic shojo series that has been remade many times.
