Seika Academy is Japan’s most prestigious high school, attended by the children of the country’s wealthiest and most influential families. The school is unofficially ruled by F4, a group of four elite boys led by the feared and arrogant Haruto Kanzaki. Everything changes when Aiko Nakamura, a scholarship student from a poor family, publicly stands up to Haruto after he bullies another student. She becomes the target of a red card, marking her for harassment by the entire school.
