Her most successful performance to date came at the 2013 Korea Open, where she reached the quarterfinals with a three-set win over Ons Jabeur.
She qualified into the singles main draw of the 2022 Australian Open for her major debut. She became the eighth South Korean woman to contest a Grand Slam main draw in the Open Era, and fourth this century following Cho Yoon-jeong, Jeon Mi-ra and Han Na-lae.
