Name: Yook Sung Jae
Native name: 육성재
Also Known as: Yuk Seong Jae
Nationality: South Korean
Gender: Male
Born: May 2, 1995
Age: 29

Yook Sung Jae is a South Korean singer, dancer, actor, and member of BTOB (비투비). He graduated from Hanlim Arts High School and later obtained a bachelor's degree in Practical Music from Dongshin University. However, this degree was revoked in April 2019 after the Ministry of Education found he received preferential treatment by not attending classes but getting credit through his TV appearances.

He debuted in March 2012 as the group's vocalist, face of the group and maknae with their first single album, "Insane".

He made his debut as a solo artist in March 2020 with the special album "Yook O'Clock".

He enlisted for his mandatory military service on May 11, 2020, and was discharged on November 14, 2021.

In November 2023, his exclusive contract with CUBE Entertainment (큐브엔터테인먼트) expired after 11 years, and he decided to leave the company but remains part of the group.

He is now represented by I Will Media ((주)아이윌미디어). Apart from being a singer, he has also been an MC and appeared in multiple TV dramas, variety and reality shows.
