# Radio Romance (라디오 로맨스) (TV series)
**Radio Romance** (라디오 로맨스; RR: *Radio Romaenseu*) is a 2018 South Korean television romance series starring [Yoon Doo-joon](https://www.edgepedia.org/yoon-doo-joon) and [Kim So-hyun](https://www.edgepedia.org/kim-so-hyun), broadcast on KBS2's Monday–Tuesday 22:00 (KST) slot from January 29 to March 20, 2018 in 16 episodes[1](https://host.cine21.com/db/tv/info/?tv_id=11077). Its premise joins two people at opposite ends of the radio craft: a top star who can only speak from a prepared script becomes the DJ of a live radio program that never goes as scripted, guided by a radio sub-writer (assistant writer for a radio program, handling guests and support) determined to cast him[2](https://www.yna.co.kr/amp/view/AKR20180125145700005).

## Premise
Song Geu-rim is a fourth-year radio sub-writer who is good at everything except writing scripts. To keep her radio station's program alive, she realizes the only path is to recruit the top star [Ji Soo](https://www.edgepedia.org/ji-soo)-ho as DJ, and she pursues him persistently[2](https://www.yna.co.kr/amp/view/AKR20180125145700005).
Soo-ho appears to have looks, popularity, and wealth, but the drama presents him as a well-engineered shell dating back to his child-actor years. In the booth, where a single microphone stands without a camera, he gradually discovers the appeal of what is heard over what is seen[2](https://www.yna.co.kr/amp/view/AKR20180125145700005). The production team described the goal as passing on warm comfort to viewers, the way radio turns a stranger's daily life into one's own story once the frequency is tuned[2](https://www.yna.co.kr/amp/view/AKR20180125145700005).
[KBS World](https://www.edgepedia.org/kbs-world)'s character notes fill in the supporting triangle. Soo-ho, who won a youngest Best Actor award at Cannes at 16 in the show's backstory, carries chronic depression beneath his public mask. Geu-rim leads a group of radio sub-writers and is prized for her guest-recruiting skills. PD Lee Kang, a legend of the station's second radio channel whose programs reach the top of the listening-rate charts, casts Geu-rim as main writer and Soo-ho as DJ for his new show. Actress Jin Tae-ri, a former child performer hoping for a comeback, learns a secret of Soo-ho's family and proposes a contract romance with him[5](https://www.kbsworld.co.jp/program/detail?prSn=952).
## Cast and characters
- **Yoon Doo-joon** (of Highlight) as Ji Soo-ho, a top star actor turned radio DJ[1](https://host.cine21.com/db/tv/info/?tv_id=11077) • [5](https://www.kbsworld.co.jp/program/detail?prSn=952)
- **Kim So-hyun** as Song Geu-rim, a radio sub-writer[1](https://host.cine21.com/db/tv/info/?tv_id=11077)
- **Yoon Park** as Lee Kang, the PD[1](https://host.cine21.com/db/tv/info/?tv_id=11077)
- **Yura** ([Girl's Day](https://www.edgepedia.org/girls-day)) as Jin Tae-ri, an actress[1](https://host.cine21.com/db/tv/info/?tv_id=11077)
- **Kwak Dong-yeon** as Jason, Soo-ho's high-school friend and psychiatrist[1](https://host.cine21.com/db/tv/info/?tv_id=11077) • [5](https://www.kbsworld.co.jp/program/detail?prSn=952)

The wider cast at the script reading also included Kim Byung-se, Yoon Joo-sang, Lee Won-jong, Kim Ye-ryeong, Jung Hee-tae, and Im Ji-kyu[4](https://news.kbs.co.kr/news/view.do?ncd=3589561).
## Production and scheduling
The script reading was held at the KBS annex in Yeouido with director Kim Shin-il and writer Jeon Yu-ri, ahead of a January 2018 premiere as the successor to *Jugglers* in the KBS 2TV Monday–Tuesday slot[4](https://news.kbs.co.kr/news/view.do?ncd=3589561). Cine21's database credits Moon Joon-ha as director alongside writer Jeon Yu-ri; this article reports both attributions as given[1](https://host.cine21.com/db/tv/info/?tv_id=11077).
**Olympics disruption.** The 2018 PyeongChang Winter Olympics, which the three terrestrial broadcasters began covering on February 9, forced schedule changes across regular programming. KBS moved the February 12 episode of *Radio Romance* to 22:40, forty minutes later than usual, while preempting *Golden Garden* on other dates and shifting other KBS programming; the broadcasters said scheduling would remain fluid depending on which events Korean athletes entered[8](https://web.donga.com/pdf/pdf_viewer.php?vcid=2018020810W1301).
## Release and reception
An original soundtrack was released in parts in 2018; Part 5, by Lee Seok-hoon, was issued on March 6, 2018 under LOEN Entertainment[9](https://wapbaike.baidu.com/item/%E5%B9%BF%E6%92%AD%E7%BD%97%E6%9B%BC%E5%8F%B2/22245863?fromid=22199037&fromtitle=Radio+Romance).
At the production press conference, Kim So-hyun called the drama her first work after coming of age and said the warm sensibility the radio subject offered attracted her; Yoon Doo-joon said being a radio DJ had once been his dream and that this was his first leading role on a terrestrial broadcaster[2](https://www.yna.co.kr/amp/view/AKR20180125145700005). On Rakuten Viki, the series holds a 9.2 rating from about 26,000 users[7](https://www.viki.com/tv/35737c-radio-romance?locale=ko); on the Japanese review site Filmarks, users gave it an average of 3.5 out of 5 across 1,886 reviews[10](https://filmarks.com/dramas/1847/3378).
In South Korea, full episodes stream on wavve, with no free streaming option listed[6](https://www.justwatch.com/kr/TV-%ED%94%84%EB%A1%9C%EA%B7%B8%EB%9E%A8/radio-romaenseu). Viki carries the series with subtitles in English, Korean, Portuguese, and more than two dozen further languages[7](https://www.viki.com/tv/35737c-radio-romance?locale=ko), and KBS World Japan has programmed it under the title ラジオ ロマンス[5](https://www.kbsworld.co.jp/program/detail?prSn=952).
