K-Pop and J-Pop Charts: aespa Tops Billboard’s World Albums as MAYU Takes Hiatus and Korean Dramas Dominate Buzz Rankings

Music and drama fandoms across Asia kept busy this week as Billboard chart updates, rising television buzz, and a sudden artist health break all played out within days of each other. In South Korea, SBS’s My Royal Nemesis and Netflix’s Teach You a Lesson led weekly “buzz” rankings for dramas and actors, while K-pop acts continued to dominate Billboard’s World Albums chart. Meanwhile, in Japan, Little Glee Monster member MAYU announced a hiatus after becoming unwell during a live event.

aespa’s “LEMONADE” takes No. 1 on Billboard’s World Albums chart

According to Soompi’s roundup of Billboard’s World Albums chart for the week ending June 14, aespa’s latest release LEMONADE debuted at No. 1. The album also marked a significant crossover moment for the group, becoming aespa’s first record in three years to break into the top 10 of the Billboard 200.

Chart stability remained a theme beyond the top spot. Soompi reports that CORTIS’s EP GREENGREEN held steady at No. 2 in its fifth week on the World Albums chart. The same publication notes it was CORTIS’s first release to spend four weeks in the Billboard 200 top 50. CORTIS’s earlier EP COLOR OUTSIDE THE LINES also climbed back to No. 4 in its 39th week.

Other major acts rounded out the upper positions: LE SSERAFIM’s PUREFLOW moved in at No. 3; BTS’s long-running Proof stayed strong at No. 5 after 208 weeks, while BTS’s 2020 Japanese album Map of the Soul: 7 ~The Journey~ rose to No. 15. ILLIT’s MAMIHLAPINATAPAI held No. 6, and Stray Kids placed multiple projects on the list, including KARMA at No. 7 and DO IT at No. 12.

Weekly drama buzz: “My Royal Nemesis” and “Teach You a Lesson” lead

While charts reflected music momentum, entertainment attention in South Korea appeared to concentrate on two new-to-current television hits. Soompi reports that for the third consecutive week, SBS’s My Royal Nemesis remained at No. 1 on Good Data Corporation’s weekly ranking of dramas that generated the most buzz.

Good Data’s methodology, as summarized by Soompi, relies on analyzing news articles, blog posts, online communities, videos, and social media engagement for dramas currently airing or set to begin airing. Within that framework, My Royal Nemesis also fueled cast-level momentum: the drama’s performers claimed three of the top six actor positions. Lim Ji Yeon ranked No. 2, Heo Nam Jun No. 3, and Jang Seung Jo No. 6.

On the actor list, Netflix’s Teach You a Lesson took the top spot. Kim Moo Yeol ranked No. 1 among buzzworthy actors, and Soompi notes that the cast of Teach You a Lesson captured four of the top 10 positions overall—Jin Ki Joo at No. 6, Lee Sung Min at No. 8, and Block B’s P.O at No. 9.

Other entries in the top drama tier included tvN’s The Legend of Kitchen Soldier at No. 3 and JTBC’s Reborn Rookie jumping to No. 4. ENA’s rom-com Doctor on the Edge entered at No. 5, while Coupang Play’s Absolute Value of Romance debuted at No. 10.

J-pop update: Little Glee Monster member MAYU pauses activities after incident

Across the East Asia entertainment landscape, the tone briefly shifted from chart competition to artist health and safety. Koreaboo reports that Little Glee Monster management announced MAYU’s hiatus on June 11 following an incident at a commemorative event for the release of the group’s latest single.

As described by Koreaboo, MAYU became unwell while performing, forcing the event to be halted partway. The outlet says she underwent a medical examination afterward and that her condition has stabilized with no major health concerns reported. In consultation with her doctor, the management decided she would take a break from activities to focus on recovery.

Importantly for fans tracking group schedules, Koreaboo adds that Little Glee Monster will continue promotions in the interim with a five-member lineup. The management also issued an apology to fans and everyone involved for the worry caused by the incident.

Why these updates matter now

Together, the three stories illustrate how rapidly audience attention can concentrate—on global streaming charts in the music space, on acting performances and online conversation in the drama space, and on the real-world vulnerability of performers in live settings.

For music, aespa’s LEMONADE debut at No. 1 on Billboard’s World Albums chart underscores the continued global reach of K-pop releases, especially as multiple major groups maintain high placements simultaneously. For Korean scripted content, Good Data’s weekly buzz ranking shows that a small number of dramas can dominate not only overall discussion but also individual cast visibility. And for Japanese pop, MAYU’s hiatus highlights the operational realities of live performance—where even routine events can trigger sudden changes to public schedules.

What to watch next

In the music charts, fans and industry observers will likely monitor whether aespa can hold the LEMONADE lead in subsequent Billboard World Albums charts and whether other top debuts—such as LE SSERAFIM’s PUREFLOW and CORTIS’s GREENGREEN—can sustain their momentum into the next month.

On the drama side, the key question is whether My Royal Nemesis and Teach You a Lesson can extend their dominance in Good Data’s buzz rankings, particularly through cast-driven conversation. And for Little Glee Monster, the immediate watchpoint is the timeline for MAYU’s recovery and whether her return date is announced after a period of medical guidance—while the group continues as five for now.
