Kill This Love debuted at number 24 on the US Billboard 200 with 19,200 units sold including over 9,100 pure sales moved, making it the highest-charting album by a female K-pop group at the time.

The founder of YG Entertainment, Yang Hyun-suk, announced on February 8, 2019, that Blackpink was scheduled to release an EP in March.

[18] 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.

[19] Furthermore, it became the fastest video to reach 100 million views on YouTube, doing so in approximately 2 days and 14 hours, beating the record set by fellow Korean artist Psy with "Gentleman" in 2013.

Until then, the women are deepening their brand of K-pop for a quickly growing, language-agnostic fanbase eagerly anticipating every fierce new beat drop.

"[17] Michelle Kim from Pitchfork gave a mixed review, calling the album's production "weirdly dated, like it was crafted earlier in the decade and then forgotten in a time capsule for five years.

"[2] Kim Do-heon from IZM gave the EP 2 out of 5 stars, where he criticized the quality of the title track but was more favorable of the group's vocals in "Kick It" and "Hope Not".
