Upon release, the music video broke the record for the most views within 24 hours, accumulating 56.7 million views. An accompanying music video for the song was directed by Seo Hyun-seung and uploaded onto Blackpink's YouTube channel simultaneously with the single's release. " Kill This Love" was released on April 4, 2019, as the lead single from the extended play. The closing track, "Ddu-Du Ddu-Du (remix)" was described as a "quivering, womping club-ready Remix".

The fourth track, "Hope Not", is a soft, acoustic pop-rock balladry about break-up where the person has moved on from yearning to acceptance.

The song is about telling past lovers: “I’m okay being alone / Don’t feel bad for me / I’m going to forget you now. "Kick It", the third song, is a song with elements of Southern trap, synth bass and acoustic guitar. The second track, "Don't Know What To Do" is an EDM and pop song with throbbing bass, whistle-like hook and an acoustic guitar. The song contains "blaring horns and martial percussion", with Rosé and Jisoo leading the "impassioned" pre-choruses about breaking up. The opening track, " Kill This Love" is a stomping, brassy electropop track with trap elements. A live recording of the Japanese version of "Kill This Love", recorded in the Tokyo Dome on December 4, 2019, was included in the group's third live album Blackpink 2019-2020 World Tour In Your Area – Tokyo Dome, released on May 6, 2020, through Universal Music Japan. The album missed its initial release date and was released on October 16, 2019. On July 26, it was announced that the group would release a Japanese version album of their EP Kill This Love through Interscope Records on September 11, 2019.

Between March 31 and April 1, multiple individual teaser pictures were posted onto their social media accounts. The single and EP were announced on March 25. Yang Hyun-suk, founder of YG, announced on February 8, 2019, that Blackpink was set for a new release with an EP in March. It was certified Platinum by the Korea Music Content Association (KMCA) in June 2019 for selling 250,000 units, becoming Blackpink's second EP to do so after Square Up, and was later certified 2× Platinum in September 2021 for selling 500,000 units. The EP reached the top ten in many territories, including Canada, Japan, New Zealand and South Korea, and the top twenty in Australia. On the Billboard 200 chart, Kill This Love debuted at number twenty four with 19,200 units including over 9,100 pure sales moved, becoming the highest-charting album by a female K-pop group at the time. The song " Don't Know What To Do" was later promoted in Korean music programs as the EP's sub-title track. The single peaked at number two in South Korea and became the group's first top-50 hit in the United States and the United Kingdom. The title track was released as the lead single.

It is their first Korean material since the release of Square Up in June 2018, and their debut release with Interscope Records.
