The BTS Effect: Inside K-Pop’s Spring Boy Group vs Girl Group Divide

Following BTS’s March 2026 comeback, April saw a sharp rise in male idol group releases, with 22 comebacks, debuts and pre-releases compared to just eight female acts. This pattern reverses in May as female groups have confirmed over 10 releases so far thus highlighting how companies navigate one of K-pop’s most competitive seasons.

Often referred to as the “Cherry Blossom Battle” , spring is considered a crucial period for the K-pop industry following the year-end award season. From May through August, university festivals, summer concerts and brand campaigns create major opportunities for artist visibility and promotion. Companies have used this time window to their favor, balancing their repertoire of artists in an even way. However, throughout the last year there has begun to be a noticeable shift on male and female promotions divisions.

Before April’s wave of spring releases, late February and March are often reserved for top-tier groups that smaller groups would not want to go against. Artists such as BTS, SEVENTEEN, Stray Kids and NCT DREAM can utilize these months to generate a strong first-quarter revenue for their companies. In the past this can be seen with Jennie's “like JENNIE” release in 2025 or Jimin’s “Like Crazy” solo release in 2023. Through physical sales, touring announcements, media & overseas promotions, these artists have the ability to set the tone of their own personal goals for the year.

Furthermore, companies often favor April as a strong month for their boy groups, particularly as these often have established fandoms and strong physical album sales. Throughout this period, fan engagement strengthens and chart performance improves which gives groups a chance to build some momentum ahead of the summer or in preparation for world tours. A notable example can be BOYNEXTDOOR’s “Earth Wind & Fire”, released back in April of 2024, it went on to become one of the biggest songs of the year. This year especially after the return of BTS, by putting rookie and established groups forward in the month of April, companies could have monopolized on the increased attention male idols received.

Girl groups tend to highly succeed in the months of May as it aligns closely with university festival season and stronger digital chart competitions. In South Korea, campus festivals are some of the most important live performance opportunities as these give artists broader public exposure beyond their fandoms. Due to the fact that girl groups tend to perform strongly on domestic digital charts, companies often position releases closer to this period to be aligned to what the public will want to see. aespa’s “Supernova” and NewJeans’ “How Sweet” dominated the digital charts throughout May of 2024, with aespa being well known for May releases.

From a business perspective, spacing out their male and female artists releases helps companies maximize physical and digital sales across their repertoire.For same-label groups, it also allows the opportunity for each group to have its own ‘spotlight’ and avoid internal competition. Media coverage is also more spaced out and there are more opportunities for one group to be allowed onto various promotion schedules.

This year, however, the trend has seemed to begin shifting as HYBE appears to have concentrated their major artists releases across both April and May with acts such as TOMORROW X TOGETHER, LE SSERAFIM, BOYNEXTDOOR and ILLIT. As BTS focuses on their North American leg of their tour, it seems HYBE’s extended label activity will help the company maintain domestic market visibility. This further reflects what could be called a “BTS effect,” where heightened public attention surrounding BTS can create stronger visibility for other HYBE artists as well. Increased traffic during the BTS comeback can give labelmates additional exposure, with BTS members also promoting labelmates’ releases through TikTok challenges or reels. Rather than diminishing the individual efforts of these groups, it highlights how the presence of a major flagship act can strengthen visibility across an entire label.

The imbalance between male and female idol releases this spring is no coincidence and is all about long-term planning. In this industry, comeback timing is meticulously tied to fan activity, touring schedules, promotions and of course, market competition. April and May might look somewhat uneven on the surface, but it reveals a precise and structural pattern on how the industry seems to manage one of their most important commercial and promotional seasons.
