next album because of mental health concerns. She was said to be diagnosed with "intermittent anxiety symptoms" and would be
taking time to focus on her health.[39] On February 5, 2020, Loona released their second EP titled [#] (read as hash), along
with the title track "So What".[40] Although HaSeul did not appear in the title track, her vocals are featured on three other
songs on the album, including "365". Once peaked at number 1 on the daily Gaon Retail Album Chart,[41] the EP then debuted at
number 2 on the weekly Gaon Album Chart. On March 12, 2020, Loona won their first music show trophy with "So What" on Mnet's
M Countdown.[42]
On October 19, 2020, Loona released their third EP titled [12:00] (read as midnight),[43] accompanied by its first single
"Why Not?". HaSeul was again not involved in the album, out of her own decision to focus on the recovery of her health.[44]
The EP then became their first album to enter the Billboard 200, debuting at number 112.[45] On November 18, Loona released
the music video for "Star", another song on [12:00].[46] Peaking at number 40, "Star" is Loona's first entry on the Billboard
Mainstream Top 40, making them the second K-pop girl group to enter the chart.[47]
On June 1, 2021, Loona announced that they would be having a comeback on June 28, with their fourth EP, [&] (read as and).
[48] The following day, on June 2, a teaser was posted to Loona's official social media accounts showing twelve sets of eyes,
confirming the return of member HaSeul who had been on hiatus since early 2020.[49] On June 12, group members YeoJin, Kim Lip,
Choerry, and Go Won released the song "Yum-Yum" as a collaboration with Cocomong.[50] On September 8, they released another
collaboration song named "Yummy-Yummy".[51] On June 27, 2021, Loona announced at the end of their special clip that they are
making their Japanese debut on September 15 under Universal Music Japan sublabel EMI Records.[52] On August 27, it was announced
that Loona will release the double A-side single, "Hula Hoop / Star Seed" on September 15, with a physical CD release on October
20.[53] In December, Chuu filed an injunction to suspend her exclusive contract with Blockberry Creative.[54][55]
