She took on her first leading role in teen drama Ma Boy (2012) and transitioned into adult roles in several television series. She also hosted MBC's music program Music Core (2013–2015).

She said that while managing her acting career, she barely had time to study during her middle school days (which made her have to take her exams unprepared) and missed out in activities with her classmates, and this similarly occurred in her elementary school days.
