Profile
WEi (위아이) is a South Korean boy group introduced by OUI Entertainment on October 5, 2020 with the mini album IDENTITY : First Sight. The six-member lineup includes Jang Daehyeon, Kim Donghan, Yoo Yongha, Kim Yohan, Kang Seokhwa and Kim Junseo. Their fandom is known as RUi.
The group's catalog combines the IDENTITY trilogy and the Love series with songs such as Too Bad, Spray, NOT ENOUGH and HOME. Its October 2025 Wonderland comeback featured five performing members as Junseo pursued a separate career path.
In 2026 the agency announced a greater focus on individual and unit activity rather than regular full-group promotions. On March 27 the five participating members released SAVE, marking 2,000 days since debut. Junseo continues separate group promotions with ALPHA DRIVE ONE; Donghan and Yongha were reported to have enlisted for mandatory military service later in 2026. These schedules should not be confused with an official declaration that the WEi brand has disbanded.
