Sulli and Kim Soo Hyun appeared in a movie together.

Sulli‘s older brother has posted a cryptic message that seemingly alludes to Kim Soo Hyun.

In a post uploaded by Sulli’s older brother on his personal Instagram, he uploaded a blank post, with a caption that has left netizens speculating the “Kim” he is referring to is Kim Soo Hyun.

“Kim-ssi, I have a lot to say, but I can’t. You’re going to fall from your high position, so you better hold on tight.” — Sulli’s brother

While it is unknown exactly who Sulli’s brother is referring to, the timing of the post, the reference to a person with the surname Kim, and the mentioning of being in a high position but then falling from that place has led many to believe he is referring to Kim Soo Hyun.

Back in 2017, Sulli and Kim Soo Hyun starred in the movie Real together. The movie was criticized for not having a clear plot. Sulli received a lot of criticism after the release of the movie while Kim Soo Hyun and the directing team, led by Lee Sa Rang, failed to defend her.
