Go Won (Hangul: 고원) is the eleventh revealed member of LOONA and a member of its third sub-unit, yyxy.

She was born as Park Chae Won (Hangul: 박채원) on November 19, 2000, in Jung District, Incheon, South Korea.

She debuted on January 15, 2018 as a member and subsequently released her solo single album "Go Won" on January 30, 2018.

Early Life

Go Won was born as Park Chae Won on November 19, 2000, in Incheon, South Korea. She is the second eldest with an older brother and one younger sister. Although unknown when, Go Won decided to become an idol after attending a concert held by Oh My Girl. To train to become an idol, she joined LP Dance & Vocal Academy, specializing in dance. While training under the academy, she participated in a few dance covers and auditioned for Source Music.[1][2][3] However, she was not accepted and continued to train under LP Dance & Vocal. In January of 2018, she joined BlockBerryCreative and debuted as a member on the 15. Before pursuing her dream, Go Won attended Bakmun Girl’s High School. But in order to focus on training, she dropped out. In an interview with StarNews, she revealed that before joining BlockBerryCreative she had seen previous members' pictures in bus stations and thought "this is an unusual project." She stated that the "members would be such nice friends," and that she would enjoy being in a group like LOONA. In the same interview, it was revealed she joined the company the same month that her solo song was released, January 2018.


On January 1st, LOOΠΔ released the X1X teaser, in which every member appeared. However, due to the heavy hints of butterflies, including the spelling out and whispering of the word 'BUTTERFLY', 12 images of the insect being shown, and flashes on both Kim Lip and Go Won, fans were quick to assume the latter would play an important part in the comeback. On January 3rd, the LOOΠΔVERSE concerts were announced, and Go Won was used as the poster image.

Then, as teased in X1X, on the 11th of January, 2019, the second teaser named XIIX was posted and only featured Go Won. In it, she is seen running after the yellow truck transporting HaSeul in Let Me In, before collapsing. She is then seen on the ground, and an alter ego is looking at herself before leaving and walking towards the same plane HaSeul visited. There, she finds a single feather and after scrunching it up, 12 butterflies are quickly flashed on screen. The teaser finishes with Go Won looking at the sky, and the Islandic sentence "Fljúga eins og fiorildi", or "Fly like a butterfly", previously heard in X1X.

On January 1st, 2018, Go Won's teaser for X X was released on all SNS platforms. It was the third to be posted overall.

After the + + teaser was released on the 29th of July, 2018, LOOΠΔ announced then released thier lead single [favOriTe] on the 7th of August, 2018, their first ever song as a group.

On August 8th, 2018, Go Won's teaser was released for the + + album. She was the first member to be teased. In subsequent days, more teasers of the full group were released, as well as half-group teasers, where Go Won was part of the 'Line unit'.

LOOΠΔ's debut concert [LOOΠΔbirth] was held in Seoul on August 19th, 2018. During it, Go Won performed all 4 songs from the [+ +] album, as well as [love4eva] and [frozen] with LOOΠΔ / yyxy, and [You and Me Together] with [Olivia Hye].

The following day, the album was released to the public and the Music Video for Hi High was released. LOOΠΔ promoted for 8 weeks on music shows and on variety shows, including fan signs on August 15th, September 1st, 8th and 16th, and October 6th and 14th.

Go Won was officially revealed to be part of LOONA yyxy with Yves, Chuu and Olivia Hye, on April 27th, 2018, through the youth youth by young teaser video. Go Won is strongly believed to be represented by the 'x', due to her being the third member of the unit. Jaden Jeong, LOOΠΔ's manager, also posted a cryptic image on March 15th, 2018, with 12 shapes, thought to represent each member. The yyxy unit was represented by triangles, with the third triangle, Go Won, is inverted.

On April 16th, 2018, Go Won's promotional image was released for Beauty&thebeat. The caption read:

"기다렸어? 나도.

Have you been waiting? So have I."

Clear differences to the other 3 members' promotional pictures led to further speculation that Go Won represents the 'x' in 'yyxy'.

On May 26, 2018, new exclusive promotional pictures were released on Naver for each member of the unit. Another Naver post, which is now deleted, revealed Behind the Scene pictures of the unit in Hungary, on the 29th of May, 2018.

The autograph events for LOOΠΔ / yyxy were held June 17th and 24th, and July 1st and 8th, 2018.

On July 14th, 2018, yyxy appeared in the one video.

Go Won was teased between January 7, 2018, and January 30, 2018, when her MV was released.

Her first official fan event was with Chuu on February 10, 2018. Her second fan event was solo, on February 24, 2018. Go Won's third fan event was held on March 3rd, 2018, alongside member Chuu. Her fourth event was held alone on April 1st, 2018. Go Won's fifth and sixth fan events were held on April 7th and April 21st, 2018, both alongside 12th member, Olivia Hye.

Coincidentally with the album release, BlockBerry Creative published a NAVER article featuring Go Won, Yves and Chuu behind the scenes of "One & Only".

Go Won was part of the lineup of members attending the Up&Line event on March 17, 2018. She appeared along with Yves and Chuu during the second half of the event.

Go Won appeared in two of Olivia Hye's reveal period promotional teasers, promoting the duet Rosy from Olivia Hye (single). Therefore, the second version of Olivia Hye's physical album features both girls on the cover, the first page of the photobook, the photocard and the pre-order poster.

Go Won was part of Line&Up on June 2nd and 3rd, 2018. On the first day, yyxy performed Frozen and Love4eva. The latter track was performed twice, once with the regular dance break, once with the Limited 'Jazz' dance break, revealing a different version of the choreography . For their interviews, they had to give a short profile of themselves, MCed by HeeJin. Yves and Chuu revealed that Go Won's nickname is 'Vanilla', inspired by her hair colour, and that Yves likes kicking Go Won's bed. The members of the unit then had to draw their representative animals, and the drawing would go to members of the audience, chosen by a raffle. For the first time ever, the 12 members of LOOΠΔ were revealed together, and danced to an unreleased instrumental beat. The main difference was that on the second day, the members of yyxy had to draw their fruits instead. The unit's uniform were the 'clueless' outfits, and the outfits worn by the 12 members were black T-Shirts with black shorts.

The first teaser, also known as the 'Who's Next Girl' teaser was released on January 7, 2018. It announced the date of the name and face reveal of the 11th girl.
