Yoon Chang-jae, played by Lee Kwang- soo, is the first victim of the roulette game played by 'Masked Man' and becomes the center of the early incident. Later, he jumps into a public murder contract for a large sum of money at stake, targeting the life of Yoo Jae-myung, the second target of the roulette game.
Lee Kwang-soo portrays Yoon Chang- jae, the first target of the roulette game and a moth-like stray to the incident to win 20 billion won, as it is, raising expectations for the rough and cruel transformation he will show.
Jo Jin-woong, who plays police officer Baek Joong-sik who opposes Yoon Chang-jae, said, "I was surprised by the energy that Lee Kwang-soo exuded on set. His acting skills are so outstanding that I want to work with him in other works," raising expectations for his amazing acting.
I don’t watch much of LKS work - maybe because of access and sometimes the plot doesn’t interest me or I want him as the lead.
But I’ve always admired his dedication to physically transform for the role - mainly through haircuts that don’t perhaps show him at his best (in terms of attractiveness) and leaves him open to teasing from the cast (which he’s resigned to since Day 1). Not many actors are committed to that extent.
