Lee Yeon hee

Early life

Lee was born in the Haenam County, South Korea and grew up in Bundang. In 2002, Lee successfully signed a contract with S.M. Entertainment after she won the category of "Best Feature" in the SM Entertainment Best Youth contest. For the contest, she acted out a monologue, singing to Dana The Grace's "Until the End of the World", and also did freestyle modeling poses. After she joined the company, she began intense training lessons on acting, singing, and dancing.

2002–2006: Beginnings

Soon after she joined SM Entertainment, Lee began her career by starring in music videos for SM artists, such as boy band TVXQ, Moon Heejun, KangTa, Shinhwa, and Fly to the Sky, overtaking SM artists Kim Bomi (of M.I.L.K.) and Lee Jiyeon (commonly known as LinA, of CSJH The Grace) as "The SM music video girl". In the span of two years, she starred in eight music videos.

Though Lee had relatively steady work between modelling in magazines, commercial ads and appearing in music videos, she did not officially debut until late 2004. In November 2004, she starred as the younger version of the main character in the hit historical drama Emperor of the Sea, and appeared in the latter episodes of the daily drama My Lovely Family. Lee had her first major role in television in MBC's mini-series One Fine Day (2006).

2007–2012: Rising popularity, acting criticism

In 2007, Lee starred in romance melodrama A Millionaire's First Love alongside Hyun Bin. She also made her singing debut for the film, singing "Do-Re-Mi" from The Sound of Music and Insa for the film's original soundtrack. Lee's innocent image in the film earned her the title of "Nation's First Love" in Korea. Lee followed this with moderately successful film, M alongside Kang Dong-won; and starred alongside So Ji-sub in the short film, U-Turn.

In 2008, she starred as one of the main cast in 47th MBC Anniversary Project East of Eden. Despite the drama's success, her acting in the series received overwhelming negative criticism about her vocalization, unexpressive facial expressions, and unnatural emotional expression as problems in portraying her character. Lee returned to film, starring in Hello, Schoolgirl opposite Yoo Ji-tae. The story is based off the manhwa Soonjeong Manwha by Kang Pool.

In 2011, Lee starred opposite Jang Dong-gun, Joe Odagiri and Fan Bing-bing in Kang Je-gyu's big budget film My Way, and in pre-produced drama series Paradise Ranch by SM Entertainment alongside label-mate Shim Chang-min of boy band TVXQ. In 2012, Lee reunited with U-Turn co-star So Ji-sub in the crime thriller Phantom. Both Lee and So were named promotional ambassadors for cyber crime prevention by the National Police Agency in 2012.

2013–present: Career resurgence

In 2013, Lee made a special appearance in the historical drama Gu Family Book, where she received compliments for her improvement in acting. She next starred in romantic comedy film Marriage Blue, which tells the story of an engaged couple who experience last-minute jitters and cold feet just a week before their wedding ceremony. Lee closed the year with television series Miss Korea to positive reviews, with many considering her role as her best performance to date.

Lee further challenged herself with a provocative role as the mysterious and seductive Japanese geisha Hisako in the historical comedy Detective K: Secret of the Lost Island in 2015. She then starred in MBC's 54th anniversary drama, Splendid Politics.

In 2017, Lee starred in in SBS's fantasy romance drama Reunited Worlds alongside Yeo Jin-goo. She will also star in JYP Entertainment's pre-produced drama, The Package opposite Jung Yong-hwa.
