How Old Are the Main Cast Members of “All of Us Are Dead”?

Despite playing high school students, looking good in their uniforms, and playing their parts exceedingly well; did you know that only one of the cast members in All of Us Are Dead was actually still in high school when they were filming?

Being the only high schooler in the cast, the other cast members lovingly called Park Ji-hu “baby angel” on set. Ji-hu plays the role of Nam On-jo in All of Us Are Dead. During a recent interview we had with the cast, Ji-hu described her character as “a junior who is very popular for her upbeat, down-to-earth personality. Her father is a firefighter, so she has these survival skills that her father taught her. This kind of comes in handy at times of a crisis. She is also very smart.”

Although Ji-hu is 20 now, she was only a junior in high school when they were filming so she had to go back and forth between her actual high school and Hyosan High School. She even had to go to the set during her mid-terms and would show up in her school uniform. “All the cast members were very nice to me,” she reminisces. “They would give me some advice on how to get into college, and they would talk to me about the adult society.”

Lim Jae-hyeok, who plays Yang Dae-su, shares that Ji-hu would even call them aunties and uncles on set. In case you were wondering, here are the actual ages of the cast members we got to interview at the time of writing:

Yoon Chang-young (Lee Cheong-san): 20 years old

Lomon (Lee Su-hyeok / Bare-su): 22 years old
