TWICE Jihyo's Sister Seoyeon Debuts with HYBE's TUIDE and TWICE Member Profiles

A significant event in the K-pop scene is the official idol debut of Park Seoyeon, TWICE Jihyo's younger sister. She has joined TUIDE, a new 7-member girl group launched by HYBE's label ABD. This debut has garnered considerable attention, not only due to her famous sibling but also because it marks the entry of the third Park sister into the entertainment industry.

Park Seoyeon, born in 2008, debuted with TUIDE on August 24, 2026, releasing their first mini-album "TUNE & PLAY," featuring the title track "SUN KISS." TUIDE, composed of members Seohee, Seoyeon, Elena, Jia, Saki, Sea, and Lee Ha-nui, aims to 'Tune the tide' by harmonizing diverse cultural backgrounds, including members from Korea, the US, UK, and Japan. Meanwhile, TWICE members' profiles as of September 17, 2026, show Nayeon (born 1995, 30 years old), Jeongyeon (born 1996, 29 years old), Momo (born 1996, 29 years old), Sana (born 1996, 29 years old), and Jihyo (born 1997, 29 years old), who is the group's leader and main vocalist.

Local bloggers express keen interest in the Park sisters' collective presence in the entertainment world, with Jihyo, model/actress Lee Ha-eum, and now Seoyeon. Jihyo's advice to her sister during TUIDE's debut showcase, encouraging trust and reliance among group members, was particularly noted, reflecting her own decade of experience. Bloggers also appreciate the distinct charms and talents of TWICE members, from Nayeon's strong stage presence to Momo's powerful dancing and Sana's natural star quality, alongside Jihyo's leadership.
