Debuting on July 23, 2025, and airing on Wednesdays and Thursdays on KBS2, this fantasy romance inspired by a webtoon spans 12 episodes, each lasting around 60 minutes. Featuring K-pop idols ASTRO’s Yoon San Ha and OH MY GIRL’s Arin, alongside actor Yoo Jung Hoo and former LOONA member Chuu, the series is based on the well-loved webtoon of the same name.
This drama delves into themes of unconditional love, self-identity, and acceptance, all wrapped in a fantastical storyline that disrupts traditional relationship norms. Its light-hearted and comedic tone merges absurd situations with heartfelt moments, exploring the essence of love beyond mere physical appearances.
Astronomy Student’s Journey
Park Yoon Jae (Yoon San Ha), an astronomy student, encounters Kim Ji Eun (Arin) during a blind date at university. They quickly fall for each other and embark on what seems to be a perfect romance. However, their lives take a dramatic turn when Ji Eun unexpectedly awakens one day transformed into a striking man named Kim Ji Hoon (Yoo Jung Hoo).
This astonishing change stems from a genetic trait in Ji Eun’s family, creating a unique situation that tests their bond in unforeseen ways. The couple chooses to stick together, hoping Ji Eun will revert to her original self, yet this journey proves to be more complicated than they anticipated.
Park Yoon Jae: Love Beyond Looks
Yoon San Ha embodies the challenging role of Park Yoon Jae, a character who must navigate the intricacies of loving someone whose appearance has drastically shifted. As an astronomy student, he’s accustomed to studying distant celestial bodies, but nothing could prepare him for this intimate transformation.
His character development addresses themes of commitment, acceptance, and the authentic nature of romantic affection. Yoon Jae’s evolution from shock to gradual acceptance highlights the depth of his emotions and prompts viewers to ponder the true essence of love when stripped of societal expectations.
Kim Ji Eun/Ji Hoon: Shifting Identities
Both Arin and Yoo Jung Hoo take on the complex role of portraying the same character in different forms. Arin infuses charm and vulnerability into Ji Eun, laying the groundwork for her romance with Yoon Jae before the transformation. Her performance beautifully captures the sweetness of first love and the bewilderment of confronting an extraordinary situation.
Yoo Jung Hoo steps in as Ji Hoon, preserving Ji Eun’s core personality while adapting to a new physical appearance. The challenge lies in convincing viewers that these are the same individual while navigating the practical and emotional challenges of the transformation.
The Climax: Discovering True Love
The series builds toward pivotal moments where the couple must face whether their love can endure this supernatural hurdle. As Ji Eun/Ji Hoon grapples with her identity, Yoon Jae wrestles with his emotions, and external pressures along with internal doubts threaten to separate them.
The climax promises to delve into whether genuine love can rise above physical appearance and societal expectations, while also unraveling the mystery of if or when Ji Eun will revert to her original form.
Supporting Characters: Chuu’s Romantic Intrigue
Chuu plays a pivotal supporting role that adds another layer of intrigue to the narrative. As someone who develops feelings for Yoon Jae during this tumultuous time, her character introduces extra tension and challenges the primary couple to evaluate their commitment to each other under extraordinary circumstances.
Success on KBS2
The drama signifies a fresh approach to romantic comedy that has sparked considerable excitement due to its unique premise and K-pop idol cast. KBS2’s choice to adapt this beloved webtoon reflects confidence in unconventional storytelling that resonates with younger viewers. The series benefits from the existing fanbase of the original webtoon while infusing new elements through its talented cast. When Your Girlfriend Becomes a Man! distinguishes itself in the crowded romantic comedy genre by addressing themes of identity and acceptance through a fantastical perspective that is both entertaining and thought-provoking.
If you’re a fan of fantasy romances, identity exploration, and unconventional love stories, When Your Girlfriend Becomes a Man! is the ideal series to binge-watch on KBS2.
