Two rival high schools, one wall, and rules made to be broken. Netflix’s upcoming high school romance No Crushing Allowed has revealed its full cast, plot, and production timeline — and it’s shaping up to be a must-watch K-drama.
What’s the Story?
From Our Beloved Summer writer Lee Na Eun, No Crushing Allowed (formerly Do Not Climb Over the Wall) is set at two elite rival schools — Jinwol Boys’ High and Jinwol Girls’ High — separated by a single wall. The series follows 19-year-olds forbidden from dating who stumble into first love anyway, blending romantic comedy tropes with a coming-of-age twist.

Meet the Cast
Shin Si A, known for Resident Playbook and The Old Woman with the Knife, leads alongside Moon Sang Min (Under the Queen’s Umbrella, My Name). Lee Min Jae (Weak Hero Class 2) plays Kong Su Ho, caught in a love-hate rivalry that shakes up the central relationship. Adding star power, ITZY idol Yuna joins as transfer student Kim Lizzy — a “love supremacist” whose gossip about her old co-ed school stirs chaos at the strict, all-girls Jinwol.
With the table read complete and filming underway, production is on track, though fans will need to wait until late 2027 for the premiere.
