It's Okay to Not Be Okay
Based on the webtoon The Baby Bear's Cave, this K-drama reimagined the source material by focusing on psychological depth rather than a simple romance. The original webtoon had a lighthearted tone, but the drama introduced complex characters like Ko Moon-young, a children's book author with antisocial personality disorder, and Moon Gang-tae, a caregiver struggling with his brother's autism. The drama added fairy tale motifs that paralleled their trauma, creating a layered narrative. For example, the episode titles reference classic fairy tales, and the animations within the drama symbolize emotional healing. The drama also expanded the subplot of Sang-tae, the autistic brother, giving him agency and a voice. By exploring themes of mental health, family, and forgiveness, the adaptation surpassed the original's emotional impact.
The Uncanny Counter
Adapted from the webtoon The Amazing Rumor, this drama deepened the source material by fleshing out each counter's backstory. The webtoon focused more on action sequences, but the drama devoted episodes to the personal tragedies of the characters, such as So Mun's parents' murder and Ga Mo-tak's past as a police officer. The villain, Baek Hyang-hee, was given a tragic origin story, making her more than a one-dimensional antagonist. The drama also expanded the world-building of the afterlife and the rules of the counters' powers, providing a richer lore. The addition of emotional subplots, like the counters' found family dynamic, made the drama resonate more with viewers than the original webtoon.
True Beauty
The webtoon True Beauty had a typical love triangle, but the drama improved by giving equal depth to the second lead, Han Seo-jun. In the webtoon, his character was less developed, but the drama showed his struggles with guilt over a friend's death and his relationship with his mother. The drama also expanded the role of supporting characters, such as the female lead's family and school friends, adding realistic slice-of-life elements. The adaptation softened the bullying arcs and added redemption for antagonists, making the story more heartwarming. By focusing on self-acceptance beyond physical appearance, the drama offered a more empowering message than the webtoon's shallower portrayal.
What's Wrong with Secretary Kim
Based on the webtoon of the same name, this drama added a psychological mystery that was absent in the source. The original webtoon was a light romantic comedy with a straightforward plot, but the drama introduced a childhood trauma involving a kidnapping that linked the leads. This backstory gave depth to the male lead, Lee Young-joon, explaining his obsessive behavior and fear of abandonment. The drama also expanded the role of the female lead, Kim Mi-so, by showing her family background and her journey to self-worth. The side characters, like the eccentric brother and the office staff, received more screen time, enriching the comedic moments. The adaptation's suspenseful subplot elevated the story beyond the webtoon's flat narrative.
A Business Proposal
The webtoon The Office Blind Date was a short, fast-paced romance, but the drama expanded it with a second couple that became a fan favorite. The drama developed the relationship between Cha Sung-hoon and Jin Young-seo, giving them a separate arc that added romance and comedy. The main couple's story was also enhanced with more workplace challenges and family dynamics, such as the male lead's grandfather's disapproval. The adaptation added slapstick humor and dramatic misunderstandings that were not in the webtoon, making the series more engaging. The female lead's friend was given a stronger personality, and the overall tone was warmer. The drama's improved pacing and character development made it a standout adaptation.
Itaewon Class
Adapted from the webtoon by Gwang Jin, this drama transformed the revenge story by adding depth to the antagonist, Jang Geun-won. In the webtoon, he was a purely evil figure, but the drama explored his backstory—his abusive father, his own struggles with identity, and his twisted love for his half-brother. This made him a tragic villain rather than a cartoonish one. The drama also gave more agency to Jo Yi-seo, the female lead, who became a key strategist in the revenge plan, whereas in the webtoon she was more passive. The adaptation expanded the themes of social inequality and community, adding subplots about the local street food culture. The drama's strong character arcs and social commentary improved on the webtoon's simpler narrative.
The World of the Married
Based on the British series Doctor Foster, this K-drama localized the story and added multiple layers of emotional manipulation. The original series had a tighter focus on the couple, but the drama introduced extended families, including the husband's mother and the lover's parents, creating a more complex social web. The drama intensified the psychological warfare, with longer scenes of gaslighting and betrayal. It also added a child's perspective, showing the impact on the son, which was less explored in the original. The setting in a Korean small city added cultural nuances about reputation and gossip. The drama's 16-episode format allowed for slower burn and more twists, making the adaptation more gripping than the original British version.
