Netflix’s ‘The Devil’s Plan’ returns: get to know the cast and players of season 2

One of the most decorated Go players in history, Lee Se-dol held 18 international titles before his 2019 retirement. His 2016 match against DeepMind’s AlphaGo—particularly his lone victory, anchored by the intuitive brilliance of White 78—has entered the mythology of AI-era competition. That win continues to unsettle machine-learning circles. His retirement was, in effect, a quiet protest against a game transformed beyond recognition.

Best known for The Umbrella Academy, where he portrayed Ben Hargreeves, and the meditative sci-fi drama After Yang, Min has often played characters more watchful than expressive. His appearance in Beef further displayed his range. On The Devil’s Plan: Death Room, he arrives not as comic relief nor token celebrity, but as a figure of introspection.

As a long-standing member of Super Junior, Kyuhyun enjoys widespread fame, bolstered by his steady presence on variety shows. His foundation in classical singing and musical theatre suggests a practiced command of timing and tone—a veteran of performance. But in the show, the stakes are unscripted.

A JTBC announcer, Kang Ji-young is known less for delivering answers than for how she frames the question. Her background in journalism may offer an edge: she listens closely, speaks sparingly and likely understands the value of silence. She is a graduate of Indiana University.

A KAIST-trained biochemical engineering graduate turned actress, Yoon So-hee operates across domains. Her leap from equations to scripts suggests fluency in dual thinking. Intelligence, in her case, does not declare itself—it unfolds, quietly.

7high is the kind of player for whom The Devil’s Plan: Death Room was designed. A professional poker player and music producer, he trades in tempo, risk and controlled opacity. In a space where every glance is a signal, his instincts for silence and misdirection may prove decisive.

Still completing her university education, Lee Seung-hyun enters the room with the composed presence of a pageant winner. But in The Devil’s Plan: Death Room, surface rarely aligns with substance. Whether her academic training supports strategic depth will be tested immediately.

Already a recognised online presence, Jeong also carries the academic credibility of a Seoul National University education. His remark that Lee Se-dol is “especially scary” betrays a sharpened understanding of both strategy and performance. He knows how to read a room—and play to it.

Model and KAIST engineering student, Choi Hyun-joon lives at the intersection of appearance and logic. He straddles two registers—projection and precision. The Devil’s Plan: Death Room is likely to pressure-test both.

Known for her bright, spontaneous persona, Chuu brings contrast to a cast dominated by calculation. But openness can be a kind of strategy. Whether her emotional transparency becomes a liability or a form of social jujitsu will define her arc.

The show’s sole medical professional, Kim Ha-rin is trained in the aesthetics and precision of plastic surgery. Her discipline requires restraint, detachment and judgement—qualities not far removed from the demands of psychological strategy.

At just 19, Park Sang-yeon has already claimed gold at the International Physics Olympiad. He represents pure academic intelligence—measurable, methodical, meticulous. But The Devil’s Plan: Death Room is also a game of noise and nuance. Whether analysis alone will suffice is uncertain.

Trained in high-stakes negotiation, Son Eun-yoo enters the arena with professional habits of parsing subtext, managing leverage and keeping composure. On Death Room, such skills are not just an asset—they are foundational to survival.

A well-known figure in board game circles, Tinno combines tactical fluency with an instinct for audience. He understands structure, turn-order, pressure. But televised play is slower, more exposed. The question isn’t whether he’s good. It’s whether he can be read.

‘The Devil’s Plan: Death Room’ is now streaming on Netflix.
