Yoona is a South Korean singer, actress and member of the idol girl group, Girls' Generation.
In 2002, she was cast in the SM Saturday Open Casting Audition and spent five years "doing nothing but constant training" in singing, dancing and acting.
Prior to debuting, Yoona was introduced to the public through various appearances in music videos and commercials; she first appeared in TVXQ's "Magic Castle" music video in 2005. Yoona has said that she went through a total of 200 auditions for commercials, music videos, dramas, and movies during her pre-debut days.
Her acting career began in 2007 with a small role in MBC's drama, Two Outs in the Ninth Inning. She then appeared in MBC's Woman of Matchless Beauty (2008), and was complimented by veteran actress Bae Jong-ok for her cameo performance.
In May 2008, Yoona landed her first leading role KBS's drama You Are My Destiny, playing Jang Sae-byuk. On her first day of filming, she was sent home crying by the director after making a mistake and being told she "was not yet ready for the role". She also had difficulties at first with her crying scenes. Yoona would prove her worth as an actress with the role, and credited the director for helping her grow as an actress. The drama was well-received and Yoona considered it a turning point in her career. Its first episode achieved a 23.4% ratings, and some later episodes peaked at 41.5%. Girls' Generation as a group was not well-known at the time, but Yoona was known for her character in the drama. She won several awards for this role, most notably two "Best New Actress" awards at the 2008 KBS Drama Awards and 45th Baeksang Arts Awards.
Yoona is known for her good-tempered and friendly personality. At the end of every drama filming, she expresses her gratefulness to the staff by giving them all handwritten letters and gifts. Jang Ha-jin, a former SM trainee who was supposed to be in Girls' Generation, then known as 'Super Girls', commented on Yoona in her autobiography, Tell Me Your Wish: "Just seeing her will make one happy. She is kind in nature...always giving and compromising, and likes to laugh a lot". Yoona has won various online surveys because of her "pure image" and beauty, and is the ideal type of many South Korean celebrities. She has a reputation for not trying to protect her image, and her uncontrollable laughter on variety shows and radio gained her the nickname "Alligator Yoona".
Yoona is regarded as a "television commercial queen" among the South Korean public, and has been a spokesperson for many brands such as Clean & Clear, Eider and Innisfree.
In January 2015, Yoona became a part of the UNICEF Honor Society, an organization that honors donors who have donated more than 100 million won. Speaking of this, she stated, "I didn't want this to be announced publicly at first because I wanted to help out the neighbors in need quietly. But I think it's also important to give along with many other people...I wanted to contribute to expanding the culture of giving by joining Honor Society". In March 2015, Yoona was honored with a presidential commendation for her exemplary tax payments and became an ambassador for her country's National Tax Service.
In January 2014, Yoona and South Korean singer Lee Seung-gi were confirmed to be in a relationship since September 2013.
