ヒョンビン
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".
