Nobody Expected Kim Hyang-gi to Play THIS Kind of Character

Kim Hyang-gi, the actress who captured hearts as a child star and earned critical acclaim for her mature performances in Along With the Gods and Innocent Witness, is about to surprise everyone with her most unexpected role yet. In the upcoming Coupang Play series Absolute Value of Romance, Kim takes on the role of a high school girl who leads a secret double life as a wildly popular romance novelist. The series premieres on April 17 at 8 PM KST, and based on the freshly released teaser poster and preview, it looks like nothing fans have seen from her before.

The premise alone is enough to generate buzz. Yeo Eui-ju, played by Kim Hyang-gi, appears to be an ordinary high school student during the day. But when night falls, she transforms into a bestselling romance author whose stories have captured a devoted readership. Her carefully maintained double life takes a chaotic turn when four impossibly handsome new teachers arrive at her school, becoming unwitting inspiration for her next novel and throwing her carefully compartmentalized existence into delightful disarray.

Four Teachers Who Change Everything

The series introduces a quartet of male leads who promise to make Eui-jus life considerably more complicated. Cha Hak-yeon, widely known as N from the K-pop group VIXX, takes on the role of Ga Woo-su, the teacher most likely to become the central love interest. Kim Jae-hyun plays No Da-ju, Son Jeong-hyeok portrays Jeong Gi-jeon, and Kim Dong-gyu rounds out the group as Yoon Dong-ju. Each teacher brings a distinct personality that feeds into Eui-jus creative imagination, providing her with material she never expected to find in real life.

The teaser poster released on March 20 perfectly captures the series playful tone. Kim Hyang-gi sits at the center of the image, chin resting on her hands with a mischievous grin, while the four teachers are arranged around her desk like characters who have literally leaped from the pages of her manuscripts. The tagline asks whether this ordinary high school girl might be writing romance novels at night, immediately establishing the comedic tension between Eui-jus two worlds.

The accompanying teaser preview expands on this premise by showing the moment the four teachers arrive at Eui-jus school. Their mere existence sets her creative instincts ablaze, and the preview hints at a series of increasingly awkward and hilarious situations where her secret authorial activities threaten to be exposed. The chemistry between Kim Hyang-gi and her co-stars appears natural and energetic, suggesting the series will deliver on its promise of lighthearted entertainment.

A Bold New Direction for Kim Hyang-gi

For Kim Hyang-gi, Absolute Value of Romance represents a significant creative pivot. The actress first gained fame as a child performer and went on to earn serious dramatic credentials. Her role in Innocent Witness alongside Jung Woo-sung showcased her ability to handle complex, emotionally demanding material. Her appearance in the Along With the Gods franchise demonstrated her range in big-budget fantasy productions. Now, at a point in her career where she could continue pursuing prestige projects, she has chosen instead to embrace a role that emphasizes comedy, romance, and youthful energy.

This choice feels deliberate and strategic. The high-teen genre has experienced a renaissance on Korean streaming platforms, with audiences showing strong appetite for series that combine school settings with genre twists. By pairing Kim Hyang-gis proven acting ability with the inherently entertaining concept of a secret novelist navigating school life, Coupang Play appears to be positioning the series as a flagship title for its spring lineup.

The casting of Cha Hak-yeon from VIXX adds another dimension of audience appeal. As an idol-turned-actor, Cha brings his own dedicated fanbase while also having proven his acting chops in previous drama roles. The decision to cast him alongside three rising actors creates a dynamic that should appeal to viewers who enjoy ensemble romantic comedies with multiple potential love interests.

What the Series Promises

Written by Lee Min-ju, Absolute Value of Romance has been described by Coupang Play as a dopamine fully charged high-teen series, a phrase that signals the platform is targeting viewers who want pure entertainment without heavy dramatic stakes. The series will explore the comedy inherent in Eui-jus double life, the romantic tension between a student and her teachers who unknowingly inspire her fiction, and the broader theme of creative expression as a form of personal freedom.

The BL, or Boys Love, element adds an extra layer of humor and cultural relevance. Several Korean media outlets have noted that Eui-jus novels specifically feature romantic stories between male characters, using her new teachers as models. This detail places the series within a cultural moment where BL content has become increasingly mainstream in Korean entertainment, and suggests the show will playfully engage with fan culture and the creative process.

The series will be available on Coupang Play starting April 17, accessible to both Coupang WOW members and general users. With its combination of a proven lead actress taking a surprising creative turn, an appealing ensemble of male leads, and a premise built for maximum entertainment value, Absolute Value of Romance has positioned itself as one of the most anticipated new Korean series of spring 2026.

Why K-Drama Fans Should Pay Attention

Beyond its entertainment value, the series represents an interesting trend in Korean content creation. Streaming platforms like Coupang Play are increasingly investing in genre-specific series that target particular audience segments rather than trying to appeal to everyone. Absolute Value of Romance is clearly aimed at viewers who enjoy lighthearted romantic comedies with a modern twist, and the platform is betting that Kim Hyang-gis star power combined with the shows unique premise will be enough to generate significant viewership.

For international K-drama fans, the series offers an accessible entry point into Korean high-teen entertainment. The concept of a secret double life is universally relatable, the romantic comedy elements transcend cultural boundaries, and Kim Hyang-gis growing international recognition through her film work should help the series find audiences beyond Korea. As streaming platforms continue to compete for subscribers, series like Absolute Value of Romance demonstrate that creativity and star power remain the most effective tools for capturing viewer attention in an increasingly crowded market.
