On December 31, 2015, Suzy and Baekhyun were announced to be collaborating on a duet titled "Dream", described as an R&B song with jazz and neo soul sounds and lyrics about a couple falling in love.[3] Two teaser videos for the song, the first featuring Suzy and the second featuring Baekhyun, were released on January 4 and 5 respectively.[4][5] The song was released digitally accompanied by its music video on January 7. Physical copies were later released on January 14.
Shortly after "Dream" was released, Park Geun-tae, one of the song's composers, revealed that he had been working on the song for two years, and that it took one year to get both singers to participate in its production.[6] He noticed Suzy in 2013 after listening to her soundtrack "Don't Forget Me" for the MBC television series Gu Family Book in which she also played the female lead, and later decided to choose Baekhyun as her duet partner.[6]
Music video
Throughout most of the music video for "Dream", Suzy and Baekhyun are seen performing the song and interacting with each other while sitting on stools in the center of a vintage styled room, surrounded by a jazz band consisting of four men playing the electric guitar, double bass, piano and drum set. There are also brief scenes where they are seen presumably preparing for a date; Suzy sitting in front of the mirror at a makeup table and Baekhyun putting on a suit jacket. The music video ends with the singers giving each other high five and a fist bump before standing up from the stools and thanking the band.
Chart performance
"Dream" debuted at number one on South Korea's Gaon weekly digital chart and remained at this position for three consecutive weeks.[7][8][9] The physical version also debuted at the same position on the Gaon weekly album chart.[10]
