Yoo Ah-in
In 2018, Yoo starred in Lee Chang-dong's film "Burning" opposite Steven Yeun, portraying a pure and sensitive young man, Jong-su, who tries to solve the mystery surrounding the woman he loves. Lee said the reason he cast Yoo, "Yoo Ah-in is one of the most famous Korean actors in that age group, and he's known for being good at delivering emotionally charged performances. In contrast to that, Jong-su is such a passive and shy character who doesn't show his emotions and who doesn't react, so I thought that would be really interesting for this actor to play this role.” Lee then praised, "No one else could inhabit the character of Jong-su like he did. Yoo Ah-in is irreplaceable for this role, he is capable of conveying great nuance and sensitivity."
