In I Only Want to Marry You (2026), a poignant and unforgettable Korean romantic drama, love, commitment, and personal growth take center stage. Kim So-eun stars as Joo-hyun, a successful career woman whose life takes an unexpected turn when she falls for the carefree, spontaneous Joon-ho (played by Park Seo-joon). What begins as a casual romance quickly turns into something more, forcing Joo-hyun to question everything she thought she knew about love and life.

Joo-hyun’s world is filled with structure and success, but Joon-ho, with his free spirit and easy-going nature, brings an element of unpredictability that captivates her. As their relationship blossoms, she finds herself both exhilarated and challenged, torn between her logical, controlled life and the chaotic, passionate love she’s beginning to embrace. But love is never simple, and the more Joo-hyun opens herself to him, the more she starts to realize how much she’s been holding back.

On the flip side, Joon-ho seems like the perfect match—charming, affectionate, and driven in his pursuit of Joo-hyun. However, beneath his confident exterior lies a man terrified of commitment. As he grows deeper in love with her, he’s forced to confront his own fears and uncertainties about building a future together. His journey isn’t just about falling in love; it’s about facing his past, his dreams, and the fear that loving someone fully might require sacrifices he’s not sure he’s ready to make.

Supporting the couple are Lee Dong-wook as Ji-hwan, Joo-hyun’s loyal and grounded friend, who provides a stable anchor in her life, and Han Hyo-joo as Soo-young, Joo-hyun’s voice of reason and confidant. As the story unfolds, their personal struggles and relationships intertwine with Joo-hyun and Joon-ho’s, highlighting the complexities of love, self-doubt, and friendship. The four characters each navigate their own path to happiness, bringing humor, warmth, and a deep emotional resonance to the film.

As societal pressures, family obligations, and the weight of their own insecurities bear down on them, the journey of Joo-hyun and Joon-ho becomes an emotional exploration of what it truly means to commit to someone for a lifetime. The couple faces the challenge of balancing their individual aspirations with the sacrifices required to build a future together, and along the way, they must decide whether they’re willing to take the leap into a lifelong commitment—or whether fear will hold them back.

The chemistry between Park Seo-joon and Kim So-eun is electric, bringing a depth of emotion to their characters’ journey. Their moments of passion, vulnerability, and heartache are balanced beautifully, making their romance feel authentic and relatable. Whether it’s through the small, tender gestures or the intense confrontations, the connection between Joo-hyun and Joon-ho drives the film, making it impossible not to root for them as they navigate the complexities of love and commitment.

The film’s direction and cinematography also deserve praise, with its visual storytelling perfectly capturing the intimate moments between the characters. From the quiet moments of reflection to the sweeping, grand gestures of love, every scene serves to deepen the emotional impact of the narrative. The backdrop of beautiful locations and carefully chosen settings enhances the film’s themes of growth, self-discovery, and the courage it takes to open your heart.

I Only Want to Marry You is more than just a romantic drama—it’s an exploration of the struggles that come with love, the sacrifices required for commitment, and the growth that happens when two people come together. The film leaves a lasting impression on the viewer, encouraging reflection on what it means to truly commit to someone for a lifetime.
