Netflix has confirmed the production of its new K-teen romance series "Do Not Cross the Wall" and unveiled its lineup of rising young actors.

Set against the backdrop of Jinwol Boys' High School and Jinwol Girls' High School, two prestigious rival schools separated by a single wall, the Netflix series "Do Not Cross the Wall" is a teen romantic comedy depicting the stories of 19-year-olds experiencing their first love. Set amidst an old local ghost story that "those who cross the wall will pay a price" and a strict school rule mandating "expulsion if caught dating," the drama captures the thrilling agony of near-misses and nostalgic school days everyone can relate to, modernizing soft teen emotions to spark both empathy and excitement.

High expectations surround the project as writer Lee Na-eun, who showcased delicate emotional lines in the drama "Our Beloved Summer" and the Netflix series "Melo Movie," teams up with director Lee Soo-hyun, who helmed "Secret Audit," "The Trainee," and "Shting Stars."

The combination of trending youth actors also instantly captures attention. Moon Sang-min takes on the role of Lee Chi-won, the student council president of Jinwol Boys' High School who earns everyone's trust with his flawless demeanor, anchoring the center of the series. Cynthia plays Soran, the passionate and lovely student council president of Jinwol Girls' High School. Having grown up together since childhood, the two characters are set to portray a special youthful chemistry that oscillates between rivalry and heart-fluttering romance.

Joining them is Lee Min-jae as Gong Su-ho, Chi-won's love-hate rival who intentionally approaches Soran, while Choi Hee-jin adds unpredictable tension to the story as Kim Riji, a transfer student at Jinwol Girls' High School and Soran's roommate.
