The Charming Manipulation Game
From Drunk Disgrace to Doting Granddaughter
Episode 9 showcases Ma Seo Rin’s (Hahm Eun Jung) remarkable talent for damage control. After stumbling home intoxicated and disappointing Chairman Ma (Lee Hyo Jung), she executes a flawless charm offensive that transforms his anger into adoration.
The newly released stills capture Seo Rin’s multi-layered performance: wrapping her arms around her grandfather from behind, resting her chin playfully on his shoulder, and flashing that irresistible smile that only emerges in his presence. This soft, affectionate persona stands in stark contrast to her usual bold and headstrong demeanor.

The Calculated Sweetness Behind the Smile
But viewers shouldn’t mistake this for simple familial love. Seo Rin wields her charm like a precision instrument, strategically deployed to secure her position as heir to Dream Hotel. Each smile carries calculation, every aegyo moment serves her ambition.
The production team revealed that Ma Seo Rin is “a character who knows how to use her charms to get what she wants,” highlighting how this seemingly innocent interaction actually represents a chess move in the unfolding succession battle.
The Dual Role Challenge
Two Sisters, Opposite Destinies
Hahm Eun Jung delivers a tour-de-force performance playing twin sisters with dramatically different personalities:
Oh Jang Mi – The warm-hearted older twin who dreams of opening her own restaurant. Working countless part-time jobs, she maintains her kind spirit and positive energy despite life’s challenges. Her character represents resilience and authenticity.
Ma Seo Rin – The spoiled only granddaughter of Dream Group’s chairman. Accustomed to getting everything she wants, she’s perfected the art of manipulation wrapped in adorable packaging.
The Separation That Changed Everything
In 1995, when the twins were born, the cunning Chae Hwa Young (Oh Hyun Kyung) forcibly separated them from their biological mother Jung Sook Hee (Jung So Young). Chae Hwa Young took one child and claimed her as her own, securing her entrance into Dream Group’s elite family.
The Brothers Fighting for Her Heart
The drama features a compelling love triangle—or rather, a love square—involving two brothers:
Kang Baek Ho (Yoon Sun Woo) – The charming, cheerful lawyer who’s popular but pursues only Oh Jang Mi with unwavering devotion.
Kang Jun Ho (Park Geon Il) – The cold, perfectionist Michelin three-star chef whose icy heart melts only for Oh Jang Mi.
The polar opposite brothers create passionate romantic rivalry, further complicated by the fact that both twin sisters fall for different brothers, intensifying the already tangled relationships.
Why First Man Captivates Audiences
The 30-Year Revenge Blueprint
The drama promises an explosive revenge story spanning three decades. As Seo Rin manipulates her way toward inheritance and Jang Mi discovers the truth about her stolen identity, the stage is set for a confrontation that will shake Dream Group’s foundations.
From K-Pop Idol to Dramatic Powerhouse
Hahm Eun Jung, who debuted as a T-ARA member in 2009 and began acting in 2004’s “Little Women,” brings years of experience to this challenging dual role. She recently married director Kim Byung-woo in November 2025 and previously led KBS2’s “Queen’s House.”
Her performance showcases remarkable range—switching between two identical-looking characters with completely different souls requires not just acting chops but physical transformation that viewers can feel.
The Succession Battle Begins
Episode 9’s grandfather-granddaughter moment isn’t just cute family bonding—it’s a strategic power play. As Seo Rin positions herself as Dream Hotel’s heir, viewers wonder how Chairman Ma’s boundless love will clash with the shocking revelations about her true identity that inevitably await.
The production team teased: “As Seo Rin skillfully sways her grandfather and a 30-year revenge story begins in earnest, please look forward to seeing how the fated conflict between Oh Jang Mi and Ma Seo Rin—and their two families—will unfold.”
