The film opens with a brief animated prologue set in 1961, introducing Ai Emi Takei, the daughter of a well‑respected Tokyo family, as she skis down a snowy slope and crashes into a young Makoto Taiga Satoshi Tsumabuki, leaving a scar that hints at a complicated history to come.
Eleven years later, in 1972 Tokyo, Ai is a senior in high school when Makoto Satoshi Tsumabuki unexpectedly appears and is ambushed by a local gang of boys. He fights them off single‑handedly during the film’s first musical number, instantly setting a bold, kinetic tone for what follows. Ai steps in to halt the brawl, and Makoto immediately recognizes her as the girl who injured him as a child, the memory of that scar resurfacing in a moment of uneasy recognition.
As the police arrive, Ai’s wealth and lineage are quickly apparent, and the authorities arrest the boys, including Makoto, who is slated for a reform school. Just as he is on the verge of a deeper trouble, the Saotome family, led by Masachika Ichimura, arranges for his release and secures a transfer to the prestigious Aobadai Prep School, where Ai stands as a popular, top‑tier student in both academics and sports. This crossover of privilege and delinquency becomes the central axis around which the story revolves.
Ai finds herself drawn to Makoto, and she uses her influence to sponsor his place at the new school. The film then filters through the shifting dynamics of their growing, complicated relationship, a partnership that begins with clash and restraint but slowly deepens into something more nuanced and charged. Yet the social world they inhabit is never simple: Iwashimizu, the student council president, is secretly in love with Ai, adding another layer of tension to the school’s social fabric.
The awakening of Ai’s dual life becomes a flashpoint when Iwashimizu exposes Ai’s rule‑breaking secret—her part‑time dancing at a club. Makoto, sensing leverage, tries to pressure Ai’s parents for a sum of 1 million yen, a move that strains loyalties and accelerates a dramatic turn in how both are perceived by their peers and families. The consequences ripple through their carefully drawn worlds, testing loyalties and forcing each of them to confront what they truly want from life.
The fallout leads Makoto to be expelled from Ai’s school and sent to Hanazono Trade School, a place where his “own kind” awaits. There, Gum‑ko [Sakura Ando] and Yuki [Ito Ohno], two girls who are part of a bustling gang at the trade school, become drawn to Makoto, adding new pressures and enticing possibilities to an already fraught relationship. The dynamic between Makoto’s raw, impulsive energy and Ai’s cultivated poise intensifies as their paths intersect with the vibrant, rough‑and‑tumble world of the trade school and its evolving alliances, painting a portrait of adolescence strained by class boundaries, pride, and the search for belonging.
Throughout, the film threads music, street energy, and sharp social observation, letting the romance emerge from a landscape where privilege and defiance meet head‑on. It remains rooted in the idea that love and loyalty can bend under pressure, reshaping futures in ways that are as unpredictable as the city that surrounds them.
