After making a bit-part appearance in the 2009 film 4th Period Mystery while she was still a student at Chung-Ang University, Im landed her breakthrough role when she was cast as Dan Sa-ran, a prideful, lower-middle class dancer, in the 2011 popular television series New Tales of Gisaeng. Cast alongside Sung Hoon and Han Hye-rin, the series explored the premise that the gisaeng, the Korean equivalent of a geisha or courtesan, still existed in modern-day Korea. Im was nominated for several newcomer awards for her performance and won the SBS Drama Award for Best New Star and the Korea Drama Award for Best New Actress. That same year, she had a prominent supporting role in Paradise Ranch and made a cameo appearance in Salamander Guru and The Shadows.
