Singer Hwang Young-woong's 'If You Love Me', which was scheduled to be released as the OST for KBS drama 'Prescription of Love', faced backlash from viewers due to past assault controversies. The OST production company explained that they had sufficiently reviewed past controversies when casting Hwang Young-woong, but KBS and the drama production company refuted that the song was not an official OST. KBS clearly stated that it had never used Hwang Young-woong's music as an OST and raised issues with the OST production company's promotional methods. The drama production company announced that they are currently reviewing legal matters and taking necessary actions.
