In "Our Love Has Always Been 10 Centimeters Apart," Miou Aida and Haruki Serizawa appear to be complete opposites to those around them. As third-year students approaching graduation, however, they find themselves growing closer. Miou, a reserved member of the art club who avoids attention, contrasts sharply with Haruki, the outgoing and confident leader of the film club who has already earned recognition for his directing skills. Despite their initial differences, a chance encounter during their entrance ceremony creates a bond between them that remains platonic, much to the confusion of their peers.
With only one year left in high school, Miou, Haruki, and their friends from both the art and film clubs must confront their unspoken feelings and the difficult decisions regarding their future goals. While Haruki strives to achieve his dream of becoming a professional director, Miou struggles to find her own path forward. Their journey reveals the challenges of bridging the distance between them, symbolically represented by the mere 10 centimeters that still separate them.
