Five K-dramas whose endings left viewers disappointed

Korean dramas are known for their compelling romances, emotional storytelling and unexpected twists. However, even a promising series can lose its appeal when complicated plots, underdeveloped characters or unsatisfying finales weaken the story.

Several popular K-dramas attracted audiences with intriguing concepts and memorable performances but struggled to deliver the satisfying conclusions viewers expected. Here are five series whose storytelling choices sparked divided reactions.

1. When the Phone Rings

Starring Yoo Yeon-seok and Chae Soo-bin, *When the Phone Rings* begins with a troubled marriage shaped by emotional distance, secrets and a mysterious phone call. The suspense surrounding Baek Sa-eon and Hong Hee-joo creates an engaging foundation for a psychological thriller.

As the story develops, however, the focus increasingly shifts towards romance and dramatic revelations. Additional twists and increasingly ambitious developments sometimes overshadow the original mystery. For viewers expecting a tightly constructed thriller, the change in direction weakened the show’s initial appeal.

2. Dynamite Kiss (2025)

Jang Ki-yong and Kim Ji-an star in this romantic comedy about an unexpected attraction complicated by workplace relationships and concealed identities. Its early episodes offer playful misunderstandings and lighthearted romantic tension.

The narrative becomes more crowded as the series progresses, introducing kidnappings, fires, financial problems and memory loss. These developments compete with the central romance, leaving less time to resolve the relationship naturally. The rushed final stretch also limits the emotional payoff that the earlier episodes had promised.

3. Memories of the Alhambra (2018)

Featuring Hyun Bin and Park Shin-hye, *Memories of the Alhambra* combines technology, fantasy and suspense. The story follows businessman Yoo Jin-woo, whose encounter with an augmented-reality game in Spain leads to increasingly dangerous experiences as the virtual world begins to overlap with reality.

The unusual concept and atmospheric setting initially distinguish the series from conventional thrillers. However, repeated confrontations gradually reduce the impact of its central mystery. Jung Hee-joo, played by Park Shin-hye, also receives less narrative attention than some viewers might expect. The ambiguous finale leaves important questions open, making the conclusion frustrating for audiences seeking clearer answers.

4. Queen of Tears (2024)

Kim Soo-hyun and Kim Ji-won lead this romantic drama about a married couple attempting to rebuild their relationship amid family conflict, financial troubles and a serious medical crisis.

The early episodes balance humour with emotional tension as Baek Hyun-woo and Hong Hae-in confront their troubled marriage. Their contrasting backgrounds and unresolved feelings give the story considerable emotional depth.

As the drama continues, repeated schemes by the antagonist, dangerous confrontations and further complications increasingly dominate the plot. Hae-in’s memory loss introduces another major obstacle, while the finale attempts to resolve several storylines in limited time. Although many viewers appreciated the emotional conclusion, others felt that the excessive twists distracted from the relationship at the heart of the series.

5. Twenty-Five Twenty-One (2022)

Starring Kim Tae-ri and Nam Joo-hyuk, *Twenty-Five Twenty-One* explores youthful ambition, friendship and first love against the backdrop of South Korea’s 1998 financial crisis.

Na Hee-do’s determination to succeed as a fencer and Baek Yi-jin’s struggle to rebuild his life create a moving story about growing up and finding direction during uncertain times. Their evolving relationship became one of the drama’s biggest attractions.

However, the ending divided audiences by taking the central couple away from the conventional romantic conclusion many had anticipated. Career pressures, distance and changing circumstances eventually separate them. While some viewers appreciated the realistic portrayal of relationships that do not last forever, others felt the conclusion was disappointing after such a sustained emotional investment.

Why endings matter

These five dramas demonstrate how difficult it can be to maintain a compelling story from the opening episode to the finale. An ambitious premise and strong performances can attract viewers, but excessive twists, unresolved mysteries and abrupt changes in direction can weaken the overall experience.

Ultimately, a memorable K-drama does not necessarily need a happy ending. It needs a conclusion that feels consistent with its characters, themes and emotional journey. When that connection is missing, even an otherwise engaging series can leave its audience wanting more.
