The five-piece rock band was founded in 2015, years before they took the stage under the name “Onewe”. They're also one of the very few K-pop groups that banded together themselves!

2015: Founding of “M.A.S 0094”
It started with the three friends Harin, CyA and Kanghyun, who later brought in CyA's best friend Dongmyeong and Yonghoon, whom they met at a music competition. In May 2015, the five friends founded a rock band together called “M.A.S. 0094”, short for “Make a Sound 0094”.
| Artist name | Real name | Birthday |
|---|---|---|
| Yonghoon | Jin Yonghoon | 17.08.1994 |
| Harin | Ju Harin | 29.03.1998 |
| Kanghyun | Kang Hyungu | 24.11.1998 |
| Dongmyeong | Son Dongmyeong | 10.01.2000 |
| CyA | Lee Giuk | 24.01.2000 |
After the band initially performed covers in public and donated the proceeds to good causes, their first single “Butterfly, Find a Flower” was released on August 13th. This time too, the proceeds were donated!
In March 2016, M.A.S 0094 released their first album “Feeling Good Day”, which contains the title song “Feeling Good” as well as the single.
The rock band only made their official debut in August 2016.
On August 2nd, the boys appeared on the music show “The Show” with the song “After 15 Seconds” from their first album.

In November the second single called “Starlight” was released and in December M.A.S 0094 performed as a session band for the girl group Mamamoo at the 2016 KBS Song Festival! But the year wasn't over for the band: On December 31st, they were the only Korean act to perform at the "Hello Starlight Forest New Year's Eve Concert" in China!
M.A.S 0094 began 2017 with the release of a new album - “Make Some Noise” - which also includes “Starlight”. It was the last album the band released as “M.A.S 0094”. Afterwards there were a few changes for the rock band, which was still relatively unknown.

2017 - 2018: A time full of changes
It started when the band, which had previously released music under “Modern Music”, signed a contract with the entertainment agency “RBW” (Rainbow Bridge World) in April. At that time, RBW managed, among others, the girl group Mamamoo and the vocal group Vromance. With the change of agency, M.A.S. 0094 changed their name to “MAS”.

In the same month, Dongmyeong appeared in the survival show “Produce 101 Season 2”. He competed there with four trainees from RBW, but unfortunately was eliminated at the beginning of May. In October the whole band applied for another survival show. “The Unit” mainly featured idols who had already made their debut. The show wanted to give them the chance to demonstrate their talent once again and draw attention to themselves. Four of the five MAS members were eliminated relatively early - Harin (52nd place), Yonghoon (58th place), CyA (59th place) & Kanghyun (61st place) - but Dongmyeong even made it to the finals! Unfortunately, he didn't place in the top 9 and missed the chance to debut in the project group. In the show, MAS was at least able to show what they were made of. They are not an idol group and therefore not dancers, but in “The Unit” they impressed the judges and the other participants with, among other things, how quickly they improved when given the challenge of practicing a choreography.
Undoubtedly, many future fans only got to know MAS through the show. So the group has laid all the foundations to advance their careers! MAS then changed their name one last time.
From then on the band was on the road as “Onewe”.
“Onewe” was seen for the first time in December on the reality show “RBW Trainee Life - We Will Debut”. Since November 2017, the show has actually accompanied the six-member boy band “Oneus” on their way to their debut. In episode 4, “Onewe” was added and from then on the two groups traveled together. They competed against each other in various missions or worked together. In September 2018, Onewe and Oneus even released a joint song called “Last Song”.

Not only do the two teams share the same agency and are both preparing for a debut in 2019 - in Onewe's case re-debut - but they also share a pair of twins! Son Dongju from Oneus, who goes by the stage name “Xion”, is the younger twin brother of Onewe’s “Son Dongmyeong”!
Oneus finally debuted in January 2019.
Onewe debuted under the new name on May 13, 2019 with the single album “¼”.
At this point, the band has already completed a four-year, varied journey. And as Onewe things continued no less excitingly! Less than a month later, on June 7th, Onewe made their official Japan debut with Japanese versions of the songs from ¼. The band even made it into Tower Records Japan’s “Top 10 Best-Selling Japanese Singles released by Korean Artists” list! Onewe also held two concerts in June and the second single album “2/4” was released in August. It contains, among other things, a new version of “Feeling Good”, the title song from M.A.S 0094's first album “Feeling Good Day!” It's a look back for Onewe and a reminder of the band's history for new and old fans.
After that there was actually a little respite. In October and December, fans were able to cheer on the boys live again at concerts.
On April 2, 2020, Onewe released the third single album “¾”.
The title song “Q” was composed by CyA and sung together with Mamamoo’s Hwasa! The song remains one of the band's most successful to date, with "Q" reaching number 12 on Billboard's World Digital Song Sales chart!
“¾” was followed at the end of May by Onewe’s first full-length album: “One”. It's a kind of best off of last year, because the album mainly consists of songs that were previously released on the single albums. There are also three new songs, including the title song “End of Spring”. While fans were once again able to enjoy seeing Onewe live, the band released two more albums in 2020: “Studio We: Recording” in September and the single album “Memory: Illusion” in December.
In 2021, the boys first toured with concerts until they presented their new album “Planet Nine: Alter Ego” on June 16th.
All five members participated in the album's production by either composing or writing parts of the songs. The title song “Rain To Be” was written by Kanghyun!
That year, CyA even got the chance to work on a song by the girl group “Purple Kiss”, which also belongs to RBW Entertainment. This song was none other than the lead single “Zombie” from Purple Kiss album “Hide & Seek”, which was released in September.
At the end of the year Onewe was very busy again, because after releasing the pre-release single “Star” on November 23rd, a new album entitled “Studio We: Recording #2” followed on December 7th and shortly after a special project: Over three years after “Last Song” Onewe has teamed up with Oneus again! The two teams gave their fans a new single titled “Stay” on December 21st!
The two groups are also involved with each other outside of shared singles. Onewe's CyA has worked on Oneus' songs and has uploaded Leedo songs to his Soundcloud account several times with Oneus. So we can hope that Onewe and Oneus will continue to work on joint projects in the future!
Onewe apparently didn't take a break, because another album called “Planet Nine: Voyager” was released on January 4, 2022. Most recently, the rock band released the “Special Album [시간을 담은 작은 방]” (A small room full of time) in May.

Onewe is one of the few rock bands that can successfully compete with popular idol groups, putting them in line with other well-known rock bands such as Day6, C.N.BLUE and The Rose. The boys certainly have a lot more to offer and we can't wait to find out what.
