Kyung-woo has been visually impaired since childhood, so curious about UFO, she can never see what she wants to see. Working in the counseling center, she takes the last bus home every night because she comes home late at night. And the driver of this last bus is PARKSang-hyun. The lovelorn Sang-hyun is a bus driver during the day, but after work, he hosts the show in his home like a radio jockey. Sometimes he feels lonely because he hosts the show alone. Sang-hyun and Kyung-woo didn't know each other, but one night Kyung-woo took the bus to the terminal and didn't get off, so Sang-hyun came forward to wake her up.
