Trained to Be a Champion Boxer, But Ended Up Falling for a Sickly Boy

Rin Kanzaki isn't your average high school girl-unless your average girl can bench press 90 kilos and knock out a full-grown man with one punch. With her piercing beauty and her no-nonsense attitude, she's gained a reputation as the school's "Iron Queen." Ever since she was little, Rin admired her father, a retired pro boxer, and dedicated herself to strength and discipline. Love? Dating? Not even on her radar.

Enter Yuuto Amamiya-quiet, soft-spoken, and as physically fragile as a paper crane in the rain. Born with a rare heart condition, Yuuto lives life carefully, often skipping gym class and spending his free time tucked away in the school library. He's used to being overlooked... until the day he's cornered by some punks behind the gym-and saved by Rin's flying roundhouse kick.

Their worlds couldn't be more different, but fate (and a torn school uniform) has other plans. Between shared lunches in quiet classrooms, clumsy attempts at getting to know each other, and Rin accidentally breaking doorknobs while trying to impress him, an unlikely romance begins to bloom.

She's strength. He's gentleness. Together, they might just be everything the other was missing.

A high school romcom packed with awkward confessions, one-sided arm-wrestling matches, and a love that's stronger than muscle.
