We Must Love

We Must Love is the third extended play from South Korean–Japanese boy group ONF. It was released on February 7, 2019 by WM Entertainment and distributed by Stone Music Entertainment. Consisted of five dominantly EDM and dance-pop tracks, the extended play was produced and written mostly by production team MonoTree, with member MK and Wyatt contributed lyrically. Upon its release, We Must Love became the group's longest charting release to date on the Gaon Album Chart, peaking at number five for one week and stayed for fourteen consecutive weeks on the chart, eventually became the twenty-fourth best selling release of February 2019. It was also the group's last release to feature founding member Laun, whom left the group six months after its release.

To further promote the extended play, ONF released its eponymous title track as the lead single from the extended play and proceeded with their first Asian tour with the same name in March 2019. Though uncharted, "We Must Love" has since become the group's signature song and one of their most recognized tunes.

Background and release
On January 28, 2019, WM Entertainment announced that ONF would release their third extended play on February 7, 2019, marking the group's first music release following their second Japanese single "Complete" in September 2018, and subsequently their first Korean release in eight months following You Complete Me in June 2018. In addition, the label unveiled ONF's teaser images on their official social media platforms, portraying a half-open image in a pink envelope stamped with ON and OFF (ONF) stamps and contains a big letter with the message "#ㅅㄹㅎㄱㄷㄱㅇ", which was the Korean abbreviation for their upcoming album title. Two days later, WM Entertainment unveiled the first group pyro-photograph with all members wearing black and red costume, showcasing a "dark" and more "mature" image transition from their previous "bubbly" and "bright" images. The entire tracklist was then revealed on February 1. The label then released both "We Must Love" and its parental extended play on all South Korean digital platforms on February 7, while the physical edition was released a day later.

Promotion
