Choi Ji Su, known professionally as Lia, is a South Korean singer, dancer, and member of ITZY (있지). She graduated from Seoul Performing Arts High School.

Before debuting, she was supposed to be a trainee at SM Entertainment after passing an audition. However, her parents opposed, and she had to give up her spot in the company. She later tried again and spent 2 years as a trainee.

She made her debut in February 2019 as the group's main vocalist and sub-rapper with their first single album, "It’z Different". The lead single, "Dalla Dalla", peaked at number two on the Circle Digital Chart, the Billboard K-pop Hot 100, and the US World Digital Songs chart. ITZY became the first K-pop girl group in history to achieve a "Rookie Grand Slam" by winning all the Rookie of the Year awards at the 5 major award shows of 2019. They are recognized for their "teen crush" concept and for exploring themes of independence and self-love in their music.

The group enjoys a large fanbase both domestically and internationally, often spending many months of the year on tour. They are managed by JYP Entertainment (JYP엔터테인먼트).

In September 2023, she went on hiatus after experiencing extreme tension and anxiety. She returned to the lineup and group activities in July 2024.
