Rising actress Choi Hee Jin has officially been cast as the female lead in Netflix’s upcoming original series, Do Not Climb Over the Wall. Recognized for her fresh screen presence and solid acting skills, Choi is expected to solidify her position as one of South Korea’s next-generation stars through this major lead role on a global OTT platform.

Do Not Climb Over the Wall is a coming-of-age romance set between neighboring boys’ and girls’ high schools that are separated by a single wall. The story follows 19-year-old students navigating first love under a strict school rule that expels anyone caught dating. The drama has attracted significant attention since its early production stages, as it is the latest project by writer Lee Na Eun, who earned widespread acclaim for the hit series Our Beloved Summer with her emotionally nuanced storytelling and relatable dialogue.

In the series, Choi Hee Jin will portray Kim Ri Ji, a transfer student at Jinwol Girls’ High School who believes wholeheartedly in the power of love. Her free-spirited personality shakes up the school’s rigid, study-focused environment, making her a pivotal character who brings fresh energy, conflict, and excitement to the narrative.
Choi will star alongside rising actors Moon Sang Min and Shin Si Ah, who were previously confirmed for the project. With a cast of promising young talents and Netflix’s take on a youthful high-school romance, anticipation is growing among both domestic and international viewers to see the chemistry this ensemble will bring to the screen.

The casting has drawn particular attention because Choi Hee Jin is taking over a role that was originally associated with ITZY member Yuna before the idol ultimately withdrew from the project. While the unexpected lineup change initially sparked concern among fans, industry insiders believe Choi’s proven acting ability and natural charm will bring stability to the production and further enhance the drama’s overall quality.
