The role required her to gain weight and master weightlifting techniques, earning critical praise and the Excellence Award at the 35th MBC Drama Awards.

In 2017, she expanded into voice acting, dubbing the Korean version of Trolls alongside Park Hyung-sik, and appeared in the film Love+Sling. She also collaborated with Psy on the single “Last Scene.”

Is Lee Sung-kyung Dating Lee Jong-suk?

Despite recurring search queries and fan speculation, no verified sources confirm a romantic relationship between Lee Sung-kyung and actor Lee Jong-suk. The confusion may stem from her high-profile collaborations with various leading men and the tendency for fan communities to ship co-stars.
