Recently, the new Disney+ series Perfect Crown began sharing pre-release content.
The show, starring IU and Byun Woo Seok, is set in an alternative universe where Korea is a constitutional monarchy. IU plays Seong Hui Ju, a chaebol frustrated by her commoner status, while Byun Woo Seok is a prince who has nothing beyond his title.

March 10 saw the first teaser be released, while the second was dropped on March 18.
Though the show is not yet released, some criticism has already begun.
In the second teaser, more of IU’s character’s past is shown, including her time in high school. In one moment, she is shown running through a hallway with Noh Sang Hyun, who is also dressed in a school uniform.

This was reposted on X, where many complained about the pair playing high school students, due to their ages (IU is 32, while Noh Sang Hyun is 35).
kinda getting tired of watching grown ass adults in school uniform. surely it can’t be that hard to cast young actors for such scenes.. https://t.co/5vqVtLfSOP

On the other hand, many felt that since the series is not a high school drama, it does not matter and that it could actually protect kids more.
Who tf cares if it’s some flashbacks lol, it’s not like Friendly Rivalry where the grown ass adults are in high school uniform THE WHOLE TIME. https://t.co/TpO6T2e7C2

Probably because a good amount of the series takes place in the royal academy. I don’t think those scenes are just mere flashbacks, and I also don’t think their characters were that young at that time. 😸

tbh i can’t get too mad at stuff like this given the average quality of safeguards for child actors https://t.co/ovu5Dwrdv8
