South Korean youth Leon works as an apprentice shoe repairman, and avoids contact with other people. One afternoon, he comes across a feisty drunk woman named Suna sleeping on a park bench, and for some reason finds himself unable to forget her. Kokaze, a young Japanese woman who works at the same store as Leon, is secretly attracted to him. Sang-soo visits the store to have Suna's broken shoes mended. He attends a Japanese language school with Suna's boyfriend, Ji-woo. Ji-woo harbors a secret crush on his Japanese teacher Kanako, who is in a relationship with a wheelchair-bound man named Arakawa. It just so happens that the accident that left him disabled was witnessed by Leon. The emotions of this group of seven men and women become increasingly entangled, and when each of them takes a step forward, their lives begin to tumble in unexpected directions.
