Get To Know Luminous Members Profile, Facts and Official Debut


Meet Luminous a K-Pop Group That Changed the Agency Before Its Debut

Being a K-pop idol often requires going through several months or even years of being a trainee before debuting. They usually train in an agency or entertainment company before forming an official debut line and training for a debut. But, in the K-pop industry, not everything is certain. Some groups can go through more than others, and one of the added steps can be a shift of agency.

Luminous, the group that formed and was planned to debut under DS Entertainment, went through a shift of agency and finally debuted under Barunson WIP, an agency run by a vocal coach who formerly taught K-pop stars like BTS, TWICE, and Kang Daniel.

Though they went through an agency shift, it didn’t hinder them from joining the competition of the K-pop industry. Let’s get to know the four members of Luminous, Youngbin, Suil, Steven, and Woobin.

The second one was Woobin who is the maknae and main vocalist of the group who was introduced to the public on July 29th, 2019. Then, on August 5th, 2019, it was Steven’s time to be introduced to the public, and the last one was the leader, Youngbin, who was introduced on August 20th, 2019.

Luminous is the group that has its own fictional universe. All the members symbolize different elements. Youngbin represents light, Suil is thunder, Steven is fire, and Woobin is moonlight. The group actually planned to debut in 2019 but canceled until they moved to another agency.

On September 9th, 2021, Luminous made their official debut after a delay because Youngbin was confirmed positive for COVID-19. They made their debut with their first mini album Youth. Prior to their debut, they released the pre-debut EP titled Luminous Dreaming which has five tracks on it. The first track is the title track with the same title as the title album, and the rest are tracks composed by each member. There is Youngbin with his “Star,” Suil with his “ROD (Ride or Die),” “Up All Night” by Steven, and “Orbit” by Woobin.

Their debut title track is “Run,” but, sadly, due to Youngbin still healing from COVID-19, the group decided to not hold a showcase. But, they held another event to showcase Luminous’ music performance to the public so fans would not miss their debut!

Having danced to “Run” for three hours nonstop, “Run” became one of the memorable performances for Luminous. Plus, it’s their debut title track. Luminous made sure that the performances would make people be amazed by them so it would be a miss to not watch “Run” that they performed on music shows. Check out Luminous’ debut with “Run” and their harmonious dance.

And, after making its debut in September 2021, it didn’t take long for Luminous to come back. They came back with the mini album Between Light and Darkness (Self n Ego) with “All Eyes Down” as the title track.

Going thin and thick in the K-pop industry and the shift of agency that didn’t break Luminous down makes them a group that is worth being your stan. So, who’s your bias in Luminous? Check out Luminous’ member profiles on Byeol Korea, and don’t forget to share on Twitter!
