One morning, SUZUKI Matsuri is taking the train to school when she feels someone touch her inappropriately. Unwilling to let it go, Matsuri turns and punches the person responsible, calling him a pervert. To her dismay, she realizes that she has attacked the wrong person- a wealthy man named SUMERAGAWA Omi who chose to ride the train instead of waiting for his car to be fixed. Despite her apologies, Omi is taken with Matsuri's boldness and decides he wants her to be his bride.
