OUI Boys Members Profile

Rookie boy group “OUI Boys” will debut for the first time at OUI Entertainment.

The “OUI Boys,” which is not a major entertainment office, but rather a small and medium-sized entertainment office, is a hot topic of conversation because it is made up of idols with careers that are too flashy for a small entertainment office.



OUI Entertainment released a performance video of ‘OUI Boys’ on their official YouTube channel.

After the video of the “OUI Boys” performance was released, the topic of conversation on the internet was the appearance of Kim Yohan from X1 who won the first place in the Mnet audition show “Produce X 101”.

The drama “School 2020,” in which Kim Yo-Han was scheduled to star, has been tentatively postponed due to casting issues that surfaced during the production phase.

The production of the drama was postponed and there were rumors that he would be making his solo singing debut, but Kim YoHan will not be making his solo debut, but a group debut.


The “OUI Boys” is a six-member group that includes Kim YoHan from X1, Kim DongHan from “Produce 101” season 2, Jang Daehyun from “Produce 101” season 2, Yoo Youngha from “UNDER NINETEEN” and “1THE9 (Wonder Nine)”, Kim Joon Seo, and Kang Seok Hwa from YG Jewelry Box.
