Love Smile, a small bus tour company, consists solely of husband-and-wife duo Junichi, the president and driver, and his wife Arisa, who works as the tour guide. Due to her job, Arisa wears a short skirt and cheerfully moves through the bus, capturing the full attention of male passengers with her alluring presence. Meanwhile, her husband Junichi appears slightly uneasy seeing how the men look at her. As the boundaries between work and personal life blur, complicated emotions begin to entangle the couple.
