Kill My Doubt

Kill My Doubt (stylized in all caps) is the seventh extended play (EP) by South Korean girl group Itzy, released on July 31, 2023, through JYP Entertainment, and Republic Records, eight months following the release of Cheshire (2022).
Inspired by the conversations shared by the members and their company following the release of Cheshire, Kill My Doubt lyrically revolves around the message of overcoming adversity and self-doubt. The EP comprises six tracks and is supported by the lead single "Cake". The release of the EP was preceded by music videos for album tracks "Bet on Me" and "None of My Business". Commercially, Kill My Doubt debuted at number one on South Korea's Circle Album Chart with 1,299,329 copies sold in the first week of release, becoming Itzy's sixth number-one album on the chart. In October 2023, the EP was certified Million by the Korea Music Content Association (KMCA) for surpassing 1,000,000 copies sold, the group's third million-seller album.
In 2022, Itzy released their fifth and sixth extended plays. Checkmate, their fifth EP, was released on July 15 and was accompanied by a world tour of the same name, which ran from August 2022 to April 2023. While on tour, Itzy released their sixth EP, Cheshire, on November 30.
While both releases were met with commercial success, "Sneakers", the lead single of Checkmate, was subject to criticism and contention, in contrast to positive reception received by the album's B-side tracks. Meanwhile, Cheshire was seen as a "mature update" to the quintet's sound, though the pre-release single "Boys Like You" was criticized by media outlets such as NME, for having "painfully juvenile" lyrics.
Following the release of Cheshire, the quintet began working on their next release. Such plans were first revealed by member Chaeryeong in an interview with the American morning program Good Day New York on May 22, 2023. On June 18, Sports Chosun reported that Itzy would release new music in the summer, which would mark their first release in over seven months. The following day, fans sent trucks bearing protest messages to the headquarters of JYP Entertainment demanding better treatment and promotion of the group. Soon thereafter, JYP Entertainment announced the group's seventh extended play, titled Kill My Doubt, through a teaser trailer. The trailer was followed by the release of the EP's track list and details of the promotion schedule. Amid the promotions for the EP, the protests continued.
Kill My Doubt has runtime of 17 minutes and 41 seconds and consists of six tracks. Thematically, the album revolves around the message of overcoming adversity. In an interview with W Korea, member Lia explained that the EP was derived on conversations from the one-on-one interviews between the members and the company's production team during the post-production phase of Cheshire. Member Yuna added that the EP intends to "deliver the message that we should overcome and regain our confidence".
A variety of songwriters were involved in the writing of the extended play, including Black Eyed Pilseung, who had previously worked with Twice, and Park Jin-young.
The opening track, "Bet on Me", is a pop song inspired by Park's conversations with the members. The song departs from the quintet's characteristic powerful style and delves into a vulnerable approach, exploring themes of anxiety, confidence, and empowerment. "Cake", the second track, serves as the EP's lead single, and is characterized by the use of energetic brass and drum sounds, expressing the members' confidence. The third track, "None of My Business", is a pop song that expresses apathy towards a former lover characterized a mellow, rhythmic sound.
An "album spoiler" video with audio snippets of the EP's songs and their corresponding choreographies was released online on July 16. Featuring only Yeji and Ryujin, the video prompted online debate regarding the absence of the remaining three members. The music for the lead single, "Cake", was promoted through teaser trailers released on July 26 and 28.
The EP was released on July 31, in conjunction with the music video for the "Cake". The quintet held a showcase at the SK Olympic Handball Gymnasium in support of Kill My Doubt on the day of the EP's release. A pop-up store at the Hyundai Seoul was opened in support of the EP from July 27 to August 9, where visitors were given pre-access to the EP's six tracks.
The production of the EP was chronicled in three "album documentaries" released on YouTube; the first was released on July 19.
In addition to the lead single, "Cake", B-side tracks "Bet on Me" and "None of My Business" also received music videos, serving as pre-releases. In a media interview, member Ryujin explained that "Bet on Me" received a music video as the song "best interprets the meaning of the album", while "None of My Business" received a music video as the song's characteristic rhythmic sound was suited for a summer release.
The music video was for "Bet on Me" was released online on July 3, with concept art preceding its release, while the music video for "None of My Business" followed on July 24. The video for "Bet on Me" aimed to capture the feeling of being alone, depicting the members in everyday settings, wearing clothing contrasting with their usual bold outfits. It ends with the members running through a dark tunnel, towards a bright light. In the summer-themed video for "None of My Business", the members perform choreography created by Lachica. The final music video, for the lead single "Cake", was released alongside the EP on July 31.
Multiple trailers and concept art were released to promote the EP. The EP's first teaser trailer saw the members pose confidently in streetwear on multiple sets to an ominous instrumental. In concept art released on July 11, Itzy was in a space with a "mysterious purple light" and punching bags, showcasing outfits with a "flashy sporty look". More concept art followed the next day, in which the members were seen in hip-hop inspired outfits. Concept art released on July 13 depicted them in a locker room.
Cho Sung-woon of Sports Donga compared the concept photos for "Bet on Me" to a movie poster, describing them as having a "melancholic tone". The first teaser trailer for "Cake" showcased the members in matching red and white outfits with the text "cake", performing choreography on their hands. In the second teaser trailer, the members were outdoors, where they spilled glitter and balloons from a truck.
On August 1, the Hanteo Chart reported that the album sold over 318,000 units on the day of its release.
