Park Ji-hoo plays the leading role of On-jo in ‘All of Us Are Dead’

The Netflix coming-of-age zombie K-drama focuses on a group of friends and students as their school becomes ground zero for a viral outbreak. One of the leading characters and unofficial narrators is On-jo, played by Park in All of Us Are Dead. On-jo is like any other girl who wants to confess to her longtime crush, raised by a single father, and has close friends.

In All of Us Are Dead, she becomes the group’s voice of reason when the Jonas virus, created by the school science teacher, turns their friends into monsters. Throughout the K-drama, On-jo becomes a favorite for her kind heart while fans have noticed a discrepancy in her story.

While All of Us Are Dead hit Netflix in January 2022, the K-drama was filmed years prior. According to Cosmopolitan, the cast and crew filmed the drama almost two years ago. Looking at Instagram posts from the actors, many behind-the-scenes photos are time-stamped for 2020.

According to details about the actors, All of Us Are Dead’s Park Ji-hoo is currently 18-years-old having been born in 2003. But by Korean age standards, she is closer to 20. If the K-drama was filmed in 2020, this means Park was roughly 16 or 17 at the time and a high school student just like her character.

In a cast interview for Netflix discussing what drew them to the K-drama, Park explained, “For me, as a high school student, a school is my second home, right? I think it’s very interesting as it’s a story happening in a school.” With Park still fresh to the experience of being a student, she added a level of realism to her role fans adored.

“I spent my two years of high school living as On-jo. So I’m glad I was able to relate to her in the way I did,” said Park. When discussing her relationship with the cast, she says they felt like her real school friends and the final day of filming felt like graduation.
