Netflix original series 'XO, Kitty' stars Sang Heon Lee (plays Min Ho) and Gia Kim (plays Yuri) have been revealed to be real-life siblings. 

Netflix original series 'XO, Kitty' was officially released on May 18. Quickly rising to be #1 on the platform, 'XO, Kitty' has already become a successful spin-off series to the Netflix film 'To All The Boys I've Loved Before', gathering a lot of attention. Shortly after the release of the series, what garnered even more attention was the fact that the two costars of 'XO, Kitty', Gia Kim and Sang Heon Lee, are also siblings in real-life.

On a recent interview with Teen Vogue, 'XO, Kitty' actor Choi Min Young stated, "I'm not sure if I can say this, but did you know that Gia Kim and Sang Heon Lee are siblings in real-life?" This quickly spread online, as many had not been aware of this fact. Choi Min Young continued, "The way I found out about this started when Anna Cathcart and Sang Heon Lee first contacted me [after I was cast]. While we were talking in a group chat, Lee Sang Heon suddenly asked us 'I can bring my sister too, right?' I was at first confused because while it would be nice to meet my fellow castmates' family members, I didn't necessarily want to meet them on my first meeting date with [all cast members]. So I was going to say something, but Sang Heon suddenly said, 'To be honest, my sister got casted as the role of Yuri.' So I was shocked."
