Twice Jihyo Younger Sister Park Seo yeon to Debut in HYBE New Girl Group ABD

The younger sister of Twice leader Jihyo is officially preparing to make her grand entrance into the music industry under a brand-new sub-label of entertainment giant HYBE. On May 26, 2026, HYBE’s newly established girl group label, ABD, launched its official website and social media channels. The label rolled out six highly aesthetic, kitschy short promotional films introducing the concept of their upcoming rookie team. Sharp-eyed K-pop fans immediately recognized one of the featured trainees as Park Seo-yeon, the youngest sister of Twice’s Jihyo.

Three Star-Studded Sisters Take Over the Industry

Born in 2008, Park Seo-yeon is eleven years younger than Jihyo and has previously caught the public’s eye through casual appearances on her older sister’s personal Instagram account. With her impending music debut scheduled for the second half of 2026, Jihyo’s family has officially established a powerful three-sister dynasty within the Korean entertainment scene:

• The Eldest (Jihyo): Debuted in 2015 as the main vocal and leader of the legendary JYP Entertainment group Twice, anchoring their global success for over a decade.
• The Second Sister (Park Ji-young): Currently promoting under the stage name Lee Ha-eum, earning steady industry praise as a professional fashion model and rising actress.
• The Youngest (Park Seo-yeon): Preparing to make her official debut as a core member of HYBE’s newest major girl group project.

The Legacy of Famous K-Pop Sibling Duos

The exciting news of Park Seo-yeon’s debut has put a massive spotlight back on the historic sibling duos and trios who have collectively shaped the landscape of modern Korean music. The industry has a long history of sibling success stories, including the legendary “Jung Sisters”—Jessica (formerly of Girls’ Generation) and Krystal (f(x))—as well as the critically acclaimed sibling duo AKMU.

Other prominent contemporary examples include dance powerhouses Lee Chae-yeon (formerly of IZ*ONE) and ITZY’s Chaeryeong, alongside the popular Tomorrow X Together member Huening Kai and his younger sister, Kep1er’s Huening Bahiyyih, who frequently go viral for filming dance challenges together. Furthermore, multiple multi-talented siblings have expanded across both music and acting, such as NCT’s Doyoung and his actor brother Gong Myung, Twice’s Jeongyeon and actress Gong Seung-yeon, and IVE’s Jang Wonyoung alongside her actress sister Jang Da-ah.

Inside HYBE’s Powerful New Label ABD

The highly anticipated launch of the upcoming rookie group will be fully managed by ABD, a specialized girl group label formally announced by HYBE on May 8. The name stands for their core brand slogan, “A Bold Dream.” To guarantee immediate commercial success, HYBE has handed the creative reins of the group over to Han Sung-soo, the legendary Master Professional (MP) who famously produced and developed iconic K-pop acts like Seventeen, After School, IZ*ONE, and the breakout 2024 rookie group TWS. Backed by Han Sung-soo’s proven production formula and Park Seo-yeon’s natural star power inherited from her famous family, ABD’s upcoming debut is already positioned to be one of the biggest pop cultural events of the year.
