My Dearest Nemesis

Two decades ago, a high school senior named Su-jung falls into an online friendship with a guy nicknamed Black Dragon. What begins as light banter turns into a crush and a plan to meet, ending in humiliation when the online fantasy clashes with reality. Sixteen years later, Su-jung works as a meticulous planner at Yongseong Department Store. A new head of strategic planning arrives, shaking up her routine and reopening a chapter from the past. The old misunderstandings resurface and threaten her career, while a complicated attraction rekindles as adults, forcing them to reckon with what they want now.

Directed by Lee Soo-hyun, this 2025 Korean series adapts the popular webtoon That Man Is Black Salt Dragon. It stars Mun Ka-young as Su-Jeong, a meticulous planner, with Choi Hyun-wook, Lim Se-mi, Kwak Si-yang, and Kim Young-ah in key roles.

Critics praise the show for wit balanced with vulnerability, using workplace pressure and a fraught past to look at forgiveness, trust, and adult romance. The writing keeps humor steady while letting the characters grow, making the romance feel earned rather than cute. The ensemble chemistry helps the dialogue snap and the pacing stay sharp, even when the plot treads familiar ground.

Awards: No major nominations have been announced yet for the series. The ensemble's chemistry and the sharp plotting have earned praise from viewers and critics, suggesting it could become a standout entry in future award cycles. If the season lands a second run, it may attract attention for its balance of humor and heart.

Part of the growing wave of webtoon to TV adaptations, the series links fans of the original to audiences with a shared affection for strong character work. It demonstrates that mature romance can anchor a comedy drama, and it spotlights the performances of Mun Ka-young and Choi Hyun-wook. The look and tone invite viewers to reimagine office life as fertile ground for connection.
