1. Kim Hyang Gi Reinvents Herself in a Bold, Comedic Turn

Kim Hyang Gi takes on the role of Yeo Eui-ju, an ordinary high school student who enjoys writing during the day while secretly leading a double life at night as an aspiring web novelist. Reflecting on her first impression of the script, she shared, “When I first read it, I was drawn to how comic-book-like yet multidimensional the characters felt. The more I read, the more curious I became about what would happen next.” Taking on her first comedy role, she said, “I’ve always had great respect for comedians, so I really wanted to do justice to the humor in the script and bring the character to life.” She added with a laugh, “I really wanted to be funny.” Speaking about shaping the character, she continued, “I paid a lot of attention to Eui-ju’s overall look to help define her personality.” Kim Hyang Gi showcases a fresh transformation in the series, bringing a playful and engaging energy to her portrayal of a high school student.

2. Four Teachers, Four Personalities—and Endless Chemistry

The four teachers bring distinct personalities and striking charm to the series, bringing a lively and engaging dynamic to the story. Speaking about his character Ga Woo-su, Cha Hak-yeon shared, “On the surface, he appears cold and structured, but if you look closer, he has a slightly clumsy charm, which makes him fun to watch.” Kim Jae-hyun, who plays Noh Da-ju, described his role as the group’s mood-maker, saying, “He’s the one who brings everyone together and keeps things lively with his unpredictable charm.” Kim Dong-gyu, who plays Yoon Dong-ju, also shared, “I wanted to carry on the idea of a ‘boyfriend-material teacher’ and make the character feel warm and relatable.” Son Jeong-hyuk plays Jung Gi-jeon, a dependable sports teacher who supports those around him, rounding out the group’s dynamic. Bringing together contrasting personalities and unique energy, the four teachers create a lively dynamic that adds to the series’ youthful and engaging appeal.

3. A Director Who Knows How to Capture Youth

The series is helmed by director Lee Tae-gon, known for his work on acclaimed dramas such as Hello My Twenties!, and True to Love. Speaking about what drew him to the project, Lee shared, “The script was incredibly engaging. But above all, I was drawn to the sense of youth and fun that the story brings.” Emphasizing the core theme of the series, he continued, “At its heart, this is a story about growth. High school is a time when that growth is especially significant, and those experiences we go through during that period stay with us and shape who we become. I hope that both the audience and everyone who worked on the series can share in that sense of growth.” Through his direction, Absolute Value of Romance captures the essence of youth and growth with warmth and authenticity.

4. A Cast That Feels Like Your Own School Memories 

Bringing together youthful energy, nostalgia, and relatable experiences, the student ensemble enhances the series’ vibrant and engaging tone. Sharing what makes Absolute Value of Romance stand out, Kim Dong-gyu described the series as “a refreshingly unique concept—something you don’t often see, and incredibly fun.” Son Jeong-hyuk likened its atmosphere to “the lively, bustling energy of a school break time.” Cha Hak-yeon emphasized the strong sense of youth embedded in the story, sharing, “It really made me think of youth—like running to the cafeteria as soon as it’s lunchtime. I believe viewers will be able to feel that same atmosphere, along with the themes of growth.” Kim Hyang Gi added, “I think the series will feel very healing. It brings back memories of school days, and I hope viewers follow the journey and experience both fun and heartfelt moments along the way.” A vibrant group of students at Murim Girls’ High School, including Kim Sohee as Choi Go-ya and Singaporean actress Gladys Bay as Jenny, further enriches the series’ coming-of-age story.

5. A Playful “Story Within a Story” Twist

One of the most distinctive elements of Absolute Value of Romance is its story-within-a-story structure, where the narrative expands beyond the events at school into the world of Yeo Eui-ju’s writing. Within her novel, the teachers transform into entirely different characters, creating a playful contrast and offering a new layer of fun for viewers. Cha Hak-yeon, who takes on a contrasting role as Ju Si-on within the story, shared, “There were no limits to the character. We kept asking, ‘Can we really go this far?’ Because of that, there are many unexpected moments and movements you wouldn’t typically see.” Kim Jae-hyun added, “To portray a different character, I intentionally made my movements bigger and more expressive.” Kim Hyang Gi also spoke about stepping into the story as its creator, saying, “Whenever I appear in those scenes, I found myself acting more like the math teacher—being a bit strict and even telling them, ‘Why are you saying the line like that?’” Blending reality and imagination, the series delivers a playful and unpredictable viewing experience, where characters shift between worlds in surprising and entertaining ways.

With its mix of humor, heart, and creative storytelling, Absolute Value of Romance captures the messy, magical journey of growing up. Whether it’s your first love, your wild imagination, or the friendships that shape you, this is one series that knows exactly how to hit all the right notes.

Streaming exclusively on Prime Video from April 17, with new episodes every Friday.

Prime Video today announced the upcoming premiere of Absolute Value of Romance, a youthful Korean coming-of-age series arriving exclusively on April 17. Blending awkward teenage moments with bittersweet humour, and heartfelt storytelling, the series follows a young aspiring writer navigating high school, friendship, and relationships.

The drama features a talented ensemble cast led by Kim Hyang Gi (Cashero, At Eighteen, Along with the Gods: The Two Worlds), alongside Cha Hak-yeon (Oh My Ghost Clients, Bad and Crazy), Kim Jae-hyun (Twenty-Five Twenty-One), Son Jeong-hyuk (You Are the Apple of My Eyes), Kim Dong-gyu (Dating Class), Kim Sohee (Fragile), and Singaporean actress Gladys Bay.

Absolute Value of Romance follows an ordinary high school student, Yeo Eui-ju, who leads a double life as a secret web novelist dreaming of success. When four charming new teachers arrive at her school, they become her unexpected muses. Their presence turns both her everyday life and her writing upside down.

Leading the cast is Kim Hyang Gi, one of South Korea’s most beloved young stars, who takes on the role of Yeo Eui-ju, an ordinary high school student who is average in every way and tries to keep a low profile at school. But at night, she secretly becomes a writer, posting daring adults-only novels online. Despite her enthusiasm, her work barely gets any views. Though highly observant and empathetic, she has always been hopeless when it comes to real-life romance. However, her life as a writer takes an unexpected turn when four handsome new teachers arrive at her school.

Cha Hak-yeon of K-pop boyband VIXX portrays Ga Woo-su, a gorgeous yet cold-looking man with piercing eyes who rarely smiles. Born and raised by a family of renowned mathematicians, he was a math prodigy with extraordinary memory, who taught himself to calculate numbers even before learning how to speak. However, when a life-changing incident occurred where he nearly lost his vision, he gave up on studying abroad and instead chose to become a math teacher. A new beginning at a high school and this one student, Eui-ju gets on his last nerves.

Kim Jae-hyun of rock band N.Flying portrays Noh Da-ju, a Japanese teacher and a gifted polyglot fluent in multiple languages. Always playful and sometimes mischievous, Da-ju is the ‘life of the party’ at school. Born to a wealthy family, he has been friends with Woo-su since elementary school. Nevertheless, they still squabble over everything as they’re so different as a person. However, deep in their heart, they truly care for each other like brothers.

Son Jeong-hyuk portrays Jung Gi-jeon, a luge athlete who retired due to a severe injury and became a sports teacher. Despite his masculine appearance, he is clumsy and warm on the inside, which makes him even popular among the students. Now, he has a new goal—turning Eui-ju, whom he sees as an exceptional talent in running, into his next sports prodigy.

Kim Dong-gyu portrays Yoon Dong-ju, a Korean teacher. Warm-hearted and innocent, Dong-ju’s charm is quite the opposite of his friends. Although he’s the eldest in the F4 group, he is often mistaken for the youngest because of his baby face. Treating his students with respect, he always uses honorifics and never loses his temper.

The cast also includes Kim Sohee as Choi Go-ya, a stylish and romantic-at-heart student who has been Eui-ju’s best friend for three years, and Gladys Bay as Jenny, an exchange student from Singapore who radiates positive energy wherever she goes.

Created and directed by Lee Tae-gon (Hello My Twenties!, Hello My Twenties! 2, True to Love) and written by Lee Min-ju, the series is produced by Coupang Play, Mediacorp, Good Wave Inc, and Borderless Film.
