1. Overview of Dynamite Kiss

 

Dynamite Kiss is a romantic comedy, office drama, and family-centric series that began airing on SBS in November 2025. It quickly rose in popularity, ranking high on Netflix’s global charts. As its title suggests, the story begins with a powerful and accidental summer-night kiss that unfolds into a layered relationship between two contrasting individuals.

 

Rather than focusing solely on romance, the drama expands into themes of livelihood, family conflict, personal growth, corporate power structures, and emotional healing. The female lead, Go Da-rim, enters a company through “disguised employment,” pretending to be a married woman with a child due to her pressing life circumstances. Her situation becomes complicated when she discovers that the team leader at her new job is the very man she shared the unexpected kiss with.

 

 

On the other hand, Gong Ji-hyeok, the male lead, appears to be a cold, perfectly composed star consultant at the top of his field. However, beneath his polished surface lie emotional wounds from witnessing the breakdown of his family due to his father’s infidelity. This internal fracture influences his guarded view of love, yet Da-rim’s presence begins to challenge the walls he has built.

 

The series constructs a compelling narrative not only around their romance but also through diverse characters: single fathers, ambitious heiresses, struggling families, corporate heirs, and a team of working mothers. Each character brings their own conflicts and motivations, creating a rich and immersive storyline.

 

 

 

 

2. Introduction to the Main Characters

2-1. Gong Ji-hyeok (Actor: Jang Ki-yong)

 

Gong Ji-hyeok is a star consultant leading a global K-venture firm. Known for his perfectionism and strategic mindset, he has built a reputation for not prolonging work projects—or romantic relationships—beyond six months. However, a single unexpected kiss during a summer night in Jeju shakes him deeply.

When Da-rim appears at his company as a new employee, he becomes conflicted after learning she is supposedly a married woman with a child. His romantic hesitation stems from unresolved pain caused by his father’s affair and the emotional collapse of his mother. Nevertheless, Da-rim’s presence continually disrupts his emotional boundaries.

 

2-2. Go Da-rim (Actor: Ahn Eun-jin)

 

Go Da-rim is a former civil service exam taker who spent years in failure while simultaneously bearing the financial and emotional weight of her collapsing family. When her sister causes a major financial accident and her mother becomes hospitalized, Da-rim resorts to disguising herself as a married woman to secure a job.

 

Her biggest shock occurs when she realizes that her new team leader is the man she accidentally kissed in Jeju just days earlier. Although she tries to suppress her emotions, she cannot deny her growing attraction to Ji-hyeok. Throughout the drama, Da-rim begins learning how to value her own emotions, rather than living only for others.

 

2-3. Kim Sun-woo (Actor: Kim Mu-jun)

 

Kim Sun-woo is a single father and a baby studio director. As Da-rim’s best friend of 20 years, he steps in to pose as her “fake husband” when she begins her disguised employment. This naturally reignites his long-held affections, creating emotional tension between them. His warm relationship with his son and his delicate emotional arc add depth to the story.

 

2-4. Yoo Ha-yeong (Actor: Woo Da-vi)

 

Yoo Ha-yeong is the youngest daughter of a powerful chaebol family. She is lively, bold, and unafraid to pursue what she wants. Drawn to Sun-woo’s warmth and sincerity, she becomes determined to win his heart—especially after learning about his involvement in Da-rim’s fake marriage. Her relationship with her complicated family further enriches her narrative.

 

 

 

 

3. Explanation of Core Relationship Dynamics

 

The relationships in Dynamite Kiss can be understood across four major axes.
First is the central romantic axis between Ji-hyeok and Da-rim, whose unexpected kiss becomes the catalyst for their evolving emotions.

Second is the triangle involving Da-rim, Sun-woo, and Ha-yeong. Sun-woo’s long-term affection contrasts with Ha-yeong’s bold pursuit.

Third is the family axis surrounding Ji-hyeok. His father’s affair, his mother’s psychological decline, and his half-sister’s ambitions shape the emotional tension within the story.

Lastly, the corporate axis lies within Natural Bebe, where TF team operations, internal power struggles, and company politics significantly influence character decisions and drama progression.

 

 

 

 

4. Additional Characters and Expanded Storylines

 

Da-rim’s family underscores the drama’s realism. Her mother, Jung Myeong-sun, is a resilient woman who has carried her family alone. Meanwhile, Da-rim’s younger sister, Da-jeong, inflicts severe emotional and financial damage upon the family through her reckless decisions.

 

Ji-hyeok’s family represents the more tragic dimension of the storyline. His father, Gong Chang-ho, is a powerful businessman whose infidelity destroyed the family. His mother, Kim In-ae, struggles with long-term psychiatric illness. His half-sister, Gong Ji-hye, hides her own ambitions while maintaining a façade of innocence.

 

Sun-woo’s son, Jun, plays a heartwarming role, connecting Sun-woo and Ha-yeong. Ha-yeong’s family—her calculating father, her materialistic mother, and her manipulative brother—adds layers of conflict tied to corporate succession and social power.

 

 

 

 

5. The Company “Natural Bebe” and the Mother TF Team

 

Natural Bebe, Korea’s top childcare product company, is a central setting where major conflicts unfold.
The Mother TF Team is composed of mothers with real parenting experience, and their insight shapes the company’s strategic direction. Ji-hyeok leads the team but struggles to bridge the cultural and emotional differences between himself and the mothers. Da-rim’s arrival disrupts the team dynamic as her secret identity adds tension.

 

The corporate background broadens the drama beyond romance, grounding it in workplace realities involving competition, hierarchy, and personal growth.

 

 

 

 

6. Why Dynamite Kiss Became a Hit

 

The series succeeds by delivering more than a standard romantic comedy. While it maintains a sweet, emotionally charged romantic tone, it integrates real-life issues such as job insecurity, family trauma, corporate politics, single parenthood, and the consequences of deception.

 

The chemistry between Jang Ki-yong and Ahn Eun-jin is highly praised, while Woo Da-vi and Kim Mu-jun add compelling subplots that enrich the overall narrative. Its strong emotional arcs and universal themes helped it rise to No. 3 in Netflix’s global non-English rankings.
