Are ‘XO, Kitty’ Stars Sang Heon Lee and Gia Kim Related?

The duo — who both play Kitty’s potential love interests, might we add — are actually siblings IRL!

The cast of XO, Kitty apparently didn’t know that fun tidbit until they started filming, either. Choi Min-yeong, who plays Dae, revealed to Teen Vogue how the cast found out their costars were siblings, explaining the rest of the actors were confused when Sang Heon Lee asked to add his sister Gia to their group chat.

“I was like, ‘What?’ Of course, I want to meet my cast’s family too, but not on the first day and not in our first meeting,'” he recalled. ” [Then] Sang Heon was like, ‘Oh, actually, she’s playing Yuri.’ And then I was like, ‘What?!'”

The siblings were both born in Seoul, South Korea, but they grew up in Hong Kong, with Sang Heon Lee attending an international school there. Fans quickly noticed that both actors have different accents, due to attending different schools while growing up.

Gia spent time in Los Angeles after attending the University of Hong Kong, where she studied acting at the Art of Acting Studio. As for her younger brother, Sang heon Lee went on to study Performing Arts at the University of Northampton in England.

In an interview with Her Campus, Gia explained that Hong Kong is her “second hometown.”

“Hong Kong will always have my heart,” Gia told the outlet May 2023. “When people think of Hong Kong, they think of a concrete jungle, high-rise buildings and skyscrapers — and it is that, but then there’s actually a lot of nature in Hong Kong too.”
