In My Dear Father-in-Law! I Love You! (2026), the delicate boundaries between love, family, and loyalty are blurred in a surprising and utterly heartwarming romantic comedy. The story revolves around Ji-eun (Park Shin Hye), a woman whose life is anything but simple. Married to the emotionally distant but successful Ji-hoon (Lee Jong-suk), Ji-eun is caught in a web of familial expectations and personal desires. However, her life takes an unexpected turn when she begins developing an undeniable bond with her father-in-law, played by the ever-charismatic Ma Dong Seok. What starts as a series of uncomfortable encounters blossoms into a relationship full of warmth, humor, and deep emotional connection, turning Ji-eun’s world upside down.

The chemistry between Park Shin Hye and Ma Dong Seok is palpable, but it’s their ability to convey a quiet, complex understanding that makes their dynamic truly shine. Ma Dong Seok, known for his strong, often intimidating presence, showcases a softer side of his character here. His portrayal of Ji-eun’s father-in-law is a revelation—he’s not just a gruff, stoic figure, but a man with layers, capable of tenderness and depth. Park Shin Hye’s Ji-eun is a perfect foil to his character, bringing warmth and humor to every scene. Together, they create an emotional, comedic chemistry that will have you laughing and thinking long after the credits roll.

The film’s true brilliance lies in its ability to navigate the complexities of family and romance, exploring not just love between partners, but also the love that grows between people in unexpected ways. The romantic tension between Ji-eun and her father-in-law may seem far-fetched at first glance, but the film cleverly manages to balance the absurdity with sincerity, making you root for this unconventional, forbidden connection. As Ji-eun tries to navigate her feelings for both her husband and his father, the film offers a poignant look at human connection, loyalty, and the twists that life throws at us.

At its core, My Dear Father-in-Law! I Love You! is about the unpredictability of love. It doesn’t follow a prescribed path; instead, it veers into unexpected territories, offering both laughter and a heartwarming reminder that love is often messier—and more wonderful—than we anticipate. The comedic moments, sprinkled with touching insights about family dynamics, offer a fresh take on the rom-com genre, pushing boundaries while staying deeply relatable.

The performances are, without a doubt, the highlight of the film. Lee Jong-suk’s portrayal of Ji-hoon, though emotionally distant, adds a layer of vulnerability that makes his character more than just the ‘perfect husband’ trope. As Ji-eun’s husband, he is torn between the pressure of his career and his marriage, creating a perfect tension within the narrative. Meanwhile, the supporting cast provides humor and heart, but it’s Ma Dong Seok’s understated yet powerful performance as the father-in-law that truly steals the show.

Director Lee Joo-young ensures that the film maintains a careful balance between comedy and heartfelt moments. The humor never feels forced, and the drama doesn’t overwhelm the lighter moments. Instead, it weaves together both aspects seamlessly, leaving the audience with a satisfying emotional journey that feels real and earned.

My Dear Father-in-Law! I Love You! is a romantic comedy that defies expectations. With its unique premise, top-tier performances, and a storyline full of surprises, this film offers more than just a laugh—it provides a heartfelt exploration of what happens when love defies tradition and finds its own path. It’s a film that’s equal parts funny and moving, a story that will stay with you long after the final scene.
