OnlyOneOf

Boy band OnlyOneOf debuted in May 2019 with its first EP, “dot point jump,” under 8D Entertainment.

It currently consists of six members: KB, Rie, Yoojung, Junji, Mill and Nine. Member Love left the band in August 2021. The band is known for its soft yet masculine themes and performances.

In 2022, OnlyOneOf launched its “undergrOund idOl” project, which saw each of the six members launch solo songs and music videos. The project started with Yoojung in June 2022 and ended with Nine in January 2023.

OnlyOneOf’s fandom is dubbed lyON, pronounced "lion," taken from the middle of the group name.
