Lee Sung-kyung's TV Shows and Movies
Lee Sung-kyung's television shows run from her 2014 debut in It's Okay, That's Love through Flower of Queen, Cheese in the Trap and The Doctors, all inside a two-year stretch that established her as a lead rather than a supporting face. Weightlifting Fairy Kim Bok-joo, released in 2016, gave her the title role of a college weightlifter and remains the show most viewers name first. She returned to medical drama for Dr. Romantic, playing surgeon Cha Eun-jae across its second season in 2020 and third season in 2023, and more recently joined the ensemble crime drama The Nice Guy in 2025 opposite Lee Dong-wook.
Her movie work is smaller but distinct from her television roles: she dubbed a Korean-language part in the animated Trolls in 2017, played a supporting lead in the romance Love+Sling the following year, and starred alongside Ra Mi-ran in the 2019 action comedy Miss and Mrs. Cops as a police officer investigating a spy-cam case.

Damiani followed on 19 December 2023, naming her the jeweller's brand ambassador in Korea and featuring her in a campaign for its Belle Époque and Margherita collections.
Sports and fitness
Lee has said her exercise routine is built on frequency rather than intensity, telling W Korea in 2022 that even ten minutes a day matters more than an occasional hard session. Five years earlier she described a routine centred on core exercises to keep her metabolism up, paired with home-cooked meals rather than skipped ones, since she has said that starving before a meal only leads to overeating at the next one.
Musical instruments
Lee has played piano since she was seven and has said she once majored in it and hoped to become a pianist before modeling worked out instead. Her piano playing has surfaced on Korean variety television, and in 2018 she performed several of the vocal tracks for the musical drama About Time herself.
