The 100th Love with You (2017) Spoiler-Free Summary – What It's About

In a sun‑drenched university town where summer festivals and campus rehearsals intertwine, Aoi Hinata is about to embark on a study abroad adventure that promises new horizons. Her days are filled with the familiar rhythm of lectures, late‑night band practice, and the quiet moments she steals with a record player she carries everywhere. A close‑knit circle of friends—Naoya, the earnest drummer, Tetta, the laid‑back bassist, and Rina, the supportive singer—share cramped dorm rooms, noisy streets, and the looming pressure of a pivotal concert that could define their final year together.

One ordinary July morning, a sudden accident leaves Aoi disoriented, only to awaken in the very classroom she left just a week earlier. The world she returns to feels both identical and strangely out of step, as if the calendar has slipped backward while the summer heat and the scent of fresh paint on a band poster remain unchanged. Among the familiar faces, Riku—her childhood friend and guitarist with an uncanny calm—appears to be a step ahead, his quiet confidence hinting at deeper currents beneath the surface. The film settles into a tone that blends light‑hearted youthful optimism with an undercurrent of wistful longing, inviting viewers to wonder how much of a single day can truly be reshaped.

As Aoi navigates this looping stretch of time, the story gently explores themes of memory, music, and the fragile edges of first love. The university campus becomes a tapestry of recurring moments—practice sessions, spontaneous jokes, and the unspoken tension that simmers when friends hover on the brink of something more. With each sunrise, the audience is drawn into a delicate dance between the comfort of familiar routines and the tantalizing possibility that a single choice might echo far beyond the summer that is about to end.
