When Your Wife Becomes Your Daughter — Oh Yoon Ah Opens Up About Korean Comedy Film Mismatch Hitting Theatres April 23

What if your memory reset so badly that your wife became your daughter, your dad turned into your rebellious little brother, and your best friend was now your flirtatious spouse? Korean comedy film Mismatch takes one of the most wildly inventive memory-malfunction premises in recent cinema — and actress Oh Yoon Ah is here to tell you exactly why it was worth every confusing, emotional, hilarious moment on set.

What Is Mismatch About?

Mismatch centres on Bong Soo (Oh Dae Hwan), an ordinary man whose entire world flips upside down after a sudden accident causes his memory to malfunction in the most chaotic way possible. The relationships he’s known his whole life become scrambled beyond recognition — a classic premise of amnesia in film, but twisted into something far more comedic and emotionally layered.

It’s the kind of setup that sounds like pure comedy gold — and based on Oh Yoon Ah’s candid interview, the emotional execution is just as careful as the laughs. For more Korean film and drama updates, visit TechnoSports.

Oh Yoon Ah on Playing Wife-Turned-Daughter

Oh Yoon Ah plays Ban Sung Hye, Bong Soo’s wife who — thanks to his scrambled memory — ends up occupying the role of his daughter instead. It’s a role that required a lot more thought than a typical comedy character.

She shared that the shift from wife to daughter “felt unfamiliar and wasn’t easy,” and that she spent considerable time thinking about “how convincingly this relationship could be conveyed to viewers.” Rather than leaning entirely on the absurd premise, she focused on grounding the character emotionally — bringing realistic human texture to an utterly unrealistic situation.

Her on-set chemistry with co-star Oh Dae Hwan proved to be the key. She credited his exceptional reactionary skills, noting that his natural, responsive style “allowed me to naturally convey my emotions” — and that their shared chemistry made portraying the shifting relationship feel smooth and authentic.

Why Mismatch Could Be a Surprise Hit?

Korean comedy films don’t always travel as widely internationally as K-dramas, but Mismatch has the kind of universal, character-driven humour that crosses cultural lines effortlessly. A cast anchored by Oh Dae Hwan — who is also currently in the tvN drama Filing for Love — and Oh Yoon Ah, returning to the big screen with clear passion and sincerity, gives this film a strong foundation.
