Kim Yu-Jin, known by her stage name Uee (유이) is a Korean Pop singer and actress. She is a former member of the Korean girl group After School and the sub-unit A.S. RED. She was also a member of the joint group 4Tomorrow.
Uee was listed to appear with a girl group called Five Girls ("Oh So Nyuh" in Korean) which included the current Wonder Girls member Yubin, the current Secret member and leader Hyosung, the former T-ara member and current Spica member Yang Jiwon, and the current solo artist G.NA. However, the group disbanded before their scheduled debut in 2007 due to the financial troubles of their entertainment company (Good Entertainment, which included the group Shinhwa).
However, she reappeared on television as a guest in Introducing A Star's Friend as Wonder Girl's Yubin's friend. Because "Five Girls" was not known to many people, she was simply seen as a very pretty friend of Yubin who resembles Wonder Girls youngest member Sohee.
In July, Uee was cast for MBC's historical drama, Queen Seon Duk which was well received and won various awards. In August, Uee appeared in Mighty Mouth's music video for "Love Class" with Hyuna from 4minute, after which she was cast for SBS's You're Beautiful playing Yoo He Yi. Later that month, she joined the group, 4Tomorrow, releasing the song, "Dugeunduguen Tomorrow" (Korean: "두근두근 Tomorrow", "BeatBeat Tomorrow") on October 6, 2009.
The project was composed of Uee, Seung Yeon (Kara), Hyuna (4minute) and Gain (Brown Eyed Girls). She later joined the reality show, We Got Married and was paired with Park Jae Jung. In early February, Uee was cast for MBC's "chivalry" drama, Birdie Buddy (Korean: 버디버디).
In 2011, she co-hosted the show called Night After Night with Park Myung-soo, Tak Jae-hoon, Kim Je-dong, Daesung from Big Bang and Jung Yong-hwa from C.N.Blue. She is currently a permanent cast of SBS's variety show Barefooted Friends alongside Eunhyuk, Kang Ho-dong, Kim Bum-soo, Kim Hyun-joong, Yoon Jong-shin,and Yoon Si-yoon.
Uee released her first solo single "Sok Sok Sok" on June 21, 2011.
Actor Joo Won couldn't stop complimenting UEE, whom he is coupled with in the KBS 2TV drama "Ojak Brothers".
Joo Won recently had an interview with Yonhap News and said, "UEE works really hard. I've seen her since school and she was always a striking junior of mine. We met for the first time in a while through this drama and I was curious if she had changed, but she had not at all".
Joo Won and UEE are from the Department of the Performing Arts in Sungkyunkwan University.
He said, "She was very concerned about the fact that she was a singer turned actress. Now that she's playing the role, every one is nice to her because she works so hard".
He said that he felt bad for her when she had to go through her After School schedule along with the drama.
"She seemed really tired at the end of the year I felt so bad for her. But surprisingly she was like a super-human and did everything. I think she's doing a very good job".
On October 16, 2013 it was announced that UEE would be in a new drama called Golden Rainbow which will will premiere on November 2.
In an interview with Ilgan Sports on April 1, UEE hinted that she may be graduating from After School fairly soon in order to focus on her acting. UEE revealed her plans after graduation: "After graduation, I want to focus on acting. That's why I find every performance at events precious now. It's more poignant now that I think there isn't much time left for me on stage."
After School‘s Uee was the host for the recently aired “2014 Supermodel Contest” on October 13, where she MCed alongside Han Go Eun and Choi Ki Hwan.
Uee’s voluptuous figure has garnered the public’s attention, especially with her full-length glamorous black dress. The partial see-through and velvet look on the dress with her point-makeup of red lips has truly frenzied the fans.
This year’s contest has been very competitive as there has been the largest number applicants for the first time in 23 years. The crown of the night has been honored to the winning contestant Koh Yae Sul. The show has been decorated by various K-Pop stars including performances by Jay Park, Girl’s Day, Ailee, Roy Kim, Block B, and many more musicians.
