# (12:00)

[12:00] (read as "midnight") is the third extended play by South Korean girl group Loona. It was released on October 19, 2020, by Blockberry Creative and distributed by Kakao M. Like their previous album, the EP was produced by SM Entertainment founder and producer Lee Soo-man, and the group's leader HaSeul once again did not take part in this album release to focus on her health.

## Background

On September 16 Blockberry Creative announced Loona's new mini-album titled [12:00] scheduled to be released in October. A teaser was released on the same day which opens with a shot of a clock reading 11:59 p.m. in Seoul. The teaser then shows the time in other cities, including Tokyo and London, before the clock in Korea turns to midnight. Blockberry also confirmed that member Haseul will continue her hiatus and will not be involved in the comeback, out of her own decision to focus on the recovery of her health.
On September 24 the official track list was released and "Why Not?" was announced as the lead single with a music video.

## Singles

"Why Not?" was released as the lead single and title alongside the EP on October 19, 2020.
On November 15, a music video teaser for "Star" was uploaded to the group's YouTube channel. The video was released on November 18, 2020, and the song was serviced to American contemporary radio formats on December 21, 2020, as the second single from the album.

Neil Z. Yeung from AllMusic gave the EP 4 out of 5 stars calling it another set of expertly crafted and energetic dance-pop songs. He said "From the bubble-bounce electroclash of "Why Not?" and "Hide & Seek" to the sleek "Voice" (which receives an English translation on "Star"), [12:00] wastes little time getting the body moving. Harder-edged rap anthem "OOPS!" and the yearning vocal showcase "Fall Again" offer some variety, making this effort one of the more enjoyable experiences in their catalog."
