R is ROSÉ’s debut single album, making her the second member of BLACKPINK to debut as a soloist.

In 2018, YG Entertainment announced Rosé would be debuting after JENNIE within the same year, but it never happened. Fans saw Rosé work on her solo for the first time on a clip from the 2020 documentary, BLACKPINK: Light Up the Sky, working on songs in the recording booth.

On December 30, 2020, YG Entertainment revealed that ROSÉ and her fellow member LISA would be making their solo debuts the following year and it was also reported that their music videos were already filmed.

On January 24, 2021, it was confirmed that ROSÉ would perform her solo sub-title track on BLACKPINK’s online concert THE SHOW. A day after the announcement, a teaser for the music video was posted on BLACKPINK’s YouTube channel, confirming that ROSÉ’s debut was to come soon.
