Teenager Yamato Akitsuki has relocated from the Hiroshima countryside to Tokyo to start his high school education. In exchange for room and board, he has agreed to assist his aunt and cousin in managing their bathhouse and the adjacent girls-only dormitory where he will reside. While traveling to meet his relatives, he passes a local high school track and is captivated by a high jumper practicing her technique. Later, Yamato discovers that the high jumper is not merely another dorm resident, but also his neighbor. Suzuka Asahina is a highly sought-after track and field athlete attending the same high school as Yamato. A natural perfectionist, Suzuka is repelled by Yamato's clumsy and carefree demeanor and finds it hard to be around him. Determined to win her affection, Yamato joins the track team after uncovering his latent talent for sprinting. Through his interactions with the track team, his classmates, and the perpetually inebriated college students in the dorm, Yamato finds the determination to become a better athlete and a more fitting companion for Suzuka, even if it requires pushing himself to the brink of exhaustion.
