W: Two Worlds - Characters & Cast

Initially, his motivation is to find the faceless killer who murdered his family. This is the 'context' of his existence as set by his creator. After becoming self-aware, his motivation shifts to survival and understanding his identity. Ultimately, his primary motivation becomes protecting Oh Yeon-joo and achieving a 'normal' life with her, free from the endless cycle of cliffhangers and conflict that defines his world.

Kang Chul begins as a quintessential tragic hero within a webtoon: a brilliant and wealthy man driven by revenge for his family's murder. His arc is one of existential awakening. When he realizes his world is fake and his suffering is for others' entertainment, he falls into despair and attempts suicide. However, his connection with Yeon-joo gives him a new purpose. He transforms from a character bound by his narrative to an active agent fighting for his own free will. He crosses into the real world, confronts his creator, and ultimately chooses to create his own happy ending, even if it means enduring more pain. His final transformation is from a fictional character into a human being, free from the confines of his story.

Her motivation is driven almost entirely by her love for Kang Chul. From the moment she saves him on the rooftop, her primary goal is to keep him alive. This motivation deepens as she becomes a character in his world, and her fight for his life becomes a fight for their shared future. She is also motivated by a desire to save her father from the darkness that consumes him as he loses control of his creation.

Oh Yeon-joo starts as a somewhat insecure surgical resident living in her famous father's shadow. Being pulled into the webtoon forces her into a more active, heroic role. Initially a passive observer and fan of Kang Chul, she becomes the 'key' to his life and the variable that breaks the narrative. Her arc is about finding her own agency and strength. She evolves from simply reacting to the chaotic events to actively intervening, drawing on the tablet to save Kang Chul and defy the story's tragic direction. While some critics found her character overly dependent on the male lead, her emotional resilience and willingness to sacrifice herself for love are central to the story's resolution. She is the bridge between the two worlds, and her love is what ultimately makes a new reality possible.

Initially, his motivation is to end the webtoon by killing Kang Chul, whom he resents for being everything he is not. He feels trapped by his creation's popularity and seeks to reclaim control. After the villain takes his face and threatens Yeon-joo, his motivation shifts completely. His final actions are driven by paternal love and a desire to atone for the monster he unleashed, ensuring his daughter's happiness above all else.

Oh Seong-moo begins as a frustrated, alcoholic webtoon artist who has grown to hate his own successful creation, Kang Chul. He represents a creator who has lost control, a god figure who becomes consumed by his own narrative. His arc is a descent into madness and a subsequent journey toward redemption. As the story progresses, he loses his own identity to the faceless villain he created, becoming a puppet for the story's antagonism. In the end, horrified by what he has become and driven by his love for his daughter, he chooses to sacrifice himself. His final act is one of creation, not destruction: he writes a happy ending for Kang Chul and Yeon-joo at the cost of his own existence, transforming from a destructive god to a loving father.
