Hueningkai is the youngest member of the K-pop group TOMORROW X TOGETHER (TXT), which debuted in 2019. By May 2023 he was 20 and part of a group set to headline Lollapalooza, whose most recent project had reached No. 1 on the Billboard 200. In a Consequence cover story interview conducted in Osaka, Japan, he came across as thoughtful and sentimental, and he spoke warmly about leaning on his bandmates.
Where they grew up
Consequence reports that Hueningkai grew up as a middle child and has two sisters. Becoming the youngest in a group when TXT debuted in 2019 was a new experience for him, since his bandmates are either only children or the youngest in their own families. He said it felt unfamiliar at first but gradually became more comfortable. The pages provided do not state his hometown or how he first came to music.
