Teach You a Lesson: Meet the Cast Behind the Chaos
The behind-the-scenes footage kicks off with a surprisingly soft side of Kim Moo Yeol — the man who plays a tough-as-nails character melts instantly around his co-stars. The warmth between the ensemble cast is palpable, and it explains a lot about why the show’s dynamics feel so natural on screen.

Action, Acrobatics & Green Screens — Oh My!
The making-of video pulls back the curtain on how those jaw-dropping action sequences actually come together. Kim Moo Yeol literally rolls across a road — showcasing some seriously impressive acrobatic skills — while Jin Ki Joo is filmed suspended on wires against a green screen, transforming into the fierce fighter fans have come to love.

It’s one of those rare behind-the-scenes glimpses that deepens your appreciation for the final product. These actors aren’t just performing — they’re putting in real physical work.
This kind of production commitment is very much in line with how Korean dramas have evolved over the past decade, blending cinematic-scale action with deeply character-driven storytelling — a formula that’s clearly working for global audiences on Netflix.
