The song was birthed at a songwriting camp that producer Teddy Park asked Bekuh Boom to run for Blackpink's debut studio album. Boom asked Tommy Brown and Victoria Monét to come to the sessions at LA's Westlake Studio, and the pair brought Mr. Franks along with them.
"Tommy had Franks pull up beats, and eventually Franks played the one that all of us started vibing to and decided to work on together," recalled Boom to Genius
. "Victoria brought up the subject 'ice cream' and started humming melodies that we then started writing lyrics to together in the room. From that point on we had a great back and forth of ideas for the first half of the song that was done that night."
