Wonderful Radio
Wonderful Radio (, also known as Love On-Air) is a 2012 South Korean romantic comedy film, starring Lee Min-jung and Lee Jung-jin. It is about a has-been pop star who is now a radio DJ struggling to boost listener ratings. It was released in theaters on January 5, 2012, by distributor Showbox/Mediaplex, and ran for 120 minutes.

Plot
Shin Jin-ah (Lee Min-jung), a onetime lead singer of popular girl group Purple, works as the DJ of the radio show "Wonderful Radio" on SBS station Power FM while also trying to restart her career as a solo singer-composer under her goofy manager Cha Dae-geun (Lee Kwang-soo). However, the ratings have been dropping, so when the show's producer leaves to have a baby, station manager Im (Kim Byung-ok) assigns the ambitious Lee Jae-hyeok (Lee Jung-jin) to her job with a brief to bring in some fresh ideas. Jae-hyeok is appalled by Jin-ah's casual, diva-ish work attitude and the two don't hit it off. When he challenges her to come up with a new segment for the show, she finally gets an idea from her restaurateur mother (Kim Hae-sook) in which members of the public come into the studio and sing a song to their loved ones. She calls the segment "The Song I Sing to You". The initial broadcast, involving a serving soldier, goes disastrously, but subsequent attempts, involving a brattish schoolgirl (Jo Jung-eun) and a taxi driver (Jung Man-shik), are a big success. Jin-ah and Jae-hyeok start to bond. However, In-seok (Kim Jung-tae), the manager of TV drama actress Yoon Mi-ra (Seo Young) and a major supplier of talent to the radio station, is plotting to bring Jin-ah down and replace her with Mi-ra, who still hates Jin-ah for leaving Purple at the height of its fame and causing the group's break-up.

Production
The director of Wonderful Radio is Kwon Chil-in, who previously directed Singles (2003), Hellcats (2008) and Loveholic (2010). The film's script was written by Lee Jae-ik, producer of SBS Power FM’s "Cultwo Show," who incorporated his own experiences in the movie, thereby giving viewers a realistic glimpse at the behind-the-scenes workings of a radio program.

Lee Min-jung said she enjoyed playing both a singer and radio DJ, basing her performance on popular idol groups in her schooldays such as S.E.S. and Fin.K.L. She also said she drew inspiration from her own childhood experience as an avid fan of radio shows, when she would laugh and cry at hearing peoples' stories broadcast over the airwaves.

The instrumental score was composed by Jung Soo-min and Hwang Seong-je. Along with various K-pop artists, the film's lead actors Lee Min-jung and Lee Jung-jin also contributed tracks.
