A new wave of excitement is sweeping through the K-drama community as KBS2 prepares to premiere its highly anticipated romantic comedy, My Girlfriend Is a Tough Man, on July 23, 2025, at 9:50 PM KST. Adapted from a popular webtoon, this series promises a fresh twist on campus romance with a star-studded idol cast and an inventive gender-swap storyline.
A Unique Gender-Bender Premise
My Girlfriend Is a Tough Man centers on the sweet romance between astronomy major Park Yoon Jae (played by ASTRO’s Sanha) and his girlfriend, Kim Ji Eun (Oh My Girl’s Arin). Their idyllic relationship takes an unexpected turn when Ji Eun, due to a mysterious family trait, suddenly transforms into a handsome young man, Kim Ji Hoon, portrayed by Yoo Jung Hoo. Together, Yoon Jae and Ji Eun—now Ji Hoon—must navigate the complexities of love, identity, and loyalty as they search for a way to reverse the transformation.
The drama’s gender-bending twist is more than just a comedic device; it explores themes of acceptance, self-discovery, and the fluidity of relationships. As the couple grapples with their new reality, the series delves into the emotional and social challenges that arise from such a dramatic change, all while maintaining a lighthearted and heartfelt tone.

Idol-Packed Cast Draws Buzz
The casting of major K-pop idols has fueled anticipation among fans. Sanha of ASTRO brings his charisma to the role of the steadfast boyfriend, while Arin of Oh My Girl takes on the dual challenge of portraying both the original and transformed versions of Ji Eun. Yoo Jung Hoo, known for his roles in Bitch X Rich and Durian’s Affair, plays the male incarnation of Ji Eun, adding another layer to the love triangle.
Chuu, formerly of LOONA and now a successful solo artist, plays Kang Min Ju, a popular student who develops feelings for Yoon Jae, further complicating the story’s romantic entanglements. The supporting cast includes Kim Kwang Shik, Jo Eun Sook, Lee Yoon Gun, Do Ji Won, Jeon Soo Jin, Hur Hyun Jun, and Choi Yoon Ra, promising a dynamic ensemble.
