Bad Boy (Chung Ha and Christopher song)

[2] It was released on September 23, 2020, by MNH Entertainment, Parlophone Denmark and Warner Music Korea.

[3][4] The artists' first collaboration work was originally planned to showcase during Christopher's concert in Korea this year, which was canceled due to the coronavirus pandemic.

MNH Entertainment said that Warner Music Korea offered Chung Ha the idea, and she gladly accepted it because she had been a fan of Christopher's music.

The upbeat track talks about a man who would want to be a "bad boy" to win her back ― is woven through with the artists' smooth vocals.

[7] The song topped the chart on Bugs music, and was second on Genie Music's chart, one day after the release.
