Hueningkai (휴닝카이)

The youngest member of Tomorrow X Together, Hueningkai carries a profile that extends beyond his role in one of K-pop's most prominent acts. A Korean-American artist signed to Big Hit Music, he is also a drummer and member of the band project TOENZE — a breadth of involvement that sets him apart from many of his generation in the idol world.

Debut and background

Born Kai Kamal Huening on August 14, 2002, Hueningkai brings a cross-cultural background to TXT, the five-member group that debuted under Big Hit Music and is distributed internationally through Republic Records and Universal Music LLC. As the group's maknae — the youngest member — he joined a lineup that has built a sustained presence in the global K-pop market across a run of commercially successful releases.

Beyond TXT

What distinguishes Hueningkai's profile within the group is his membership in TOENZE, where he serves as drummer. The project reflects a dimension of musicianship — live instrumental performance — that is relatively uncommon in the idol sector, and it represents a parallel strand of activity alongside his work with TXT.

Recent activity

In April 2026, TXT marked a significant moment in their career with the release of their eighth mini-album, '7TH YEAR: When the Wind Briefly Stopped in the Thicket' — the group's first release following the renewal of all members' contracts. Hueningkai was present at the showcase held at Korea University's Hwajeong Gymnasium, and in a gesture that drew particular attention from fans, he and fellow member Taehyun made an unscheduled appearance at an offline listening party, joining attendees to hear reactions to the new material directly.
