Plot

Han Sun-woo (Park Hyung-sik) is a rookie photographer who does not talk much but is kind and warm-hearted. Lee Eun-soo (Han So-hee) works as a lyricist to make a living and has an honest, bright personality. The two have been close friends for about 20 years.¹ By the time the story begins, their friendship has reached its 19-year mark.⁸

For an unstated reason, the two begin living together in the same house for two weeks. Staying together, their relationship develops romantically as feelings they can no longer ignore grow deeper and more intimate.¹^•⁵ One review describes Sun-woo as having realized eight years earlier that his feelings for Eun-soo had grown beyond friendship.⁴ Eun-soo, meanwhile, is asked to write song lyrics for a famous composer, and the love story is connected to the composition of the lyrics.⁹^•¹

Sequel

A stand-alone sequel, Soundtrack #2, aired on Disney+ in 2023. It follows a different pair of leads, with Keum Sae-rok as a struggling music lover hired as a piano tutor for her ex-boyfriend, played by Noh Sang-hyun, in a six-episode run. Time described the sequel as improving on Soundtrack #1 in every way.⁷

Music-driven format

Instead of the traditional 16-episode South Korean television series, Soundtrack #1 was intentionally produced as an ultra-short, four-episode miniseries built around a music-video-like format, in which the plot progresses directly through the characters' recording and writing of emotional songs.⁴ Instead of drafting the screenplay first and attaching songs afterward, the team put out key OST singles from performers such as Doyoung, Kyuhyun, and Lee Hi both ahead of and throughout the episodes' run, treating the words of those songs as plot points for the characters.⁴

The four episodes were titled "A Doll's Dream" (March 23, 2022), "Unrequited Love" (March 30), "I Love You" (April 6), and "My Heart Aches to Think of You" (April 13), with runtimes between roughly 38 and 53 minutes.⁵

Cast

Park Hyung-sik, a member of the K-pop boy band ZE:A, plays Han Sun-woo, and Han So-hee, known for My Name, plays Lee Eun-soo.¹⁰ The supporting cast includes Lee Jung-eun as Eun-soo's mother, Kim Ju-hun as Kang Woo-il, Yoon Byung-hee as Yoon Dong-hyun, Park Hoon as Gyeol-han, and Kim Do-shin as a CEO.¹ Seo In-guk makes a cameo in episode 3 as Jay Jun, a famous singer that Eun-soo was working with; the character does not sing in the series despite Seo being a singer.¹^•⁴

Production and reception

Director Kim Hee-won, who also directed the drama Vincenzo, led the series.¹¹ A review in the South China Morning Post described the show as sticking to conventional tropes and a familiar story without breaking new ground, while noting that there is something to be said for meeting modest expectations.¹⁰ The same paper's review called the series a poor showcase for its two leads.¹² On the audience-aggregate site AsianWiki, the series holds a user rating of 90/100 from 1,325 votes.¹

The series streams on Disney+ in the United States and other regions as part of a subscription.¹³
