Korea's most popular song writer Hee-soo runs into a nineteen-year-old boy in the elevator. Hee-soo is inspired by a new song watching him shake at her figure. She starts to tell him about women under the excuse that she's teaching him music. They fall for each other but things get complicated when her life teacher, Joon-ho who taught her about life and music comes back.
