Huening Bahiyyih (휴닝바히에) is a Korean-American member of Kep1er (케플러), born July 17, 2003 in Seongbuk-gu, Seoul. The younger sister of TXT's Hueningkai, she placed in Mnet's Girls Planet 999 in 2021 and debuted with Kep1er under WAKEONE Entertainment on January 3, 2022. When KLAP Entertainment began co-managing the group in September 2024, Bahiyyih continued as a core member through the lineup transition into 2026.
Growing up between the US and Germany before her K-pop career, she brings a multilingual ease and internationalist perspective to everything Kep1er does. As the younger sister of Kai Huening of TOMORROW X TOGETHER, she is part of one of the more compelling sibling stories in contemporary K-pop.

She opened her personal Instagram account @hiyeahhh_ in 2024, giving fans a direct line to her off-stage life.
