Play's "Absolute Value of Romance" Review: A High School Girl Writes BL Novels About Her Teachers

The Rising Mainstream Popularity of the BL Genre

One of the most rapidly growing genres that has formed a rock-solid, dedicated fandom among female viewers and readers is 'BL' (Boys' Love). In the past, this genre was largely considered a niche subculture or a highly secretive personal preference. However, its status within the modern entertainment industry has completely transformed. Moving far beyond subtle bromance, this genre—which explicitly explores affection and romance between male characters—has stepped out of the shadows to achieve widespread, mainstream popularity. It has become a significant cultural phenomenon that deeply resonates with a massive global audience, proving that diverse storytelling can easily break through traditional boundaries.

A Unique Twist on K-Drama Tropes on Coupang Play

The immense influence of this subculture in the content market is undeniable. There are now mainstream variety shows dedicated entirely to discussing the BL genre, alongside massive, specialized web platforms and video channels that exclusively distribute this type of content. Capitalizing on this powerful cultural trend in a highly clever and unique way, a brand-new original drama has recently premiered on the streaming platform Coupang Play. The series is titled The Absolute Value of Romance (로맨스의 절댓값), a show that takes a very familiar setting and flips it completely on its head, injecting a fresh, rebellious energy into the standard K-drama formula.

Meet Yeo Eui-joo: A Quirky High School Web Novelist

If you look solely at the title, The Absolute Value of Romance, you might easily mistake it for a typical, innocent, and sweet high school teen romance. The casting of actress Kim Hyang-gi, who is widely known for her pure and lovely image, certainly adds to that initial misconception. However, this drama is actually a highly charming comedy armed with a quirky premise that delightfully twists the conventional rules of romance. Kim Hyang-gi plays the female lead, Yeo Eui-joo, delivering a perfectly tailored performance. On the surface, Eui-joo appears to be just an ordinary high school student, but she harbors a massive, secret ambition: she is an amateur web novel writer.

The Harsh Reality of an Unpopular Writer with Zero Dating Experience

Despite her grand dreams, the harsh reality is that Eui-joo is a completely unknown writer with virtually zero readers for the web novel she pours her heart into. She has essentially built a massive wall between herself and her academics, making it no exaggeration to say that she has completely given up on studying at school. While she possesses an incredibly bright, positive, and cheerful personality, her actual real-life dating experience is absolutely non-existent. She is a classic "born-single daydreamer" character who relies entirely on her wildly active imagination to conceptualize the steamy, dramatic romance plots she tries to write about online.

A Fateful Encounter with Four Breathtakingly Handsome Men

Eui-joo's ordinary, quiet daily life—which previously consisted only of commuting between school, home, and her imaginary worlds—experiences a massive upheaval one day. While walking down the street, she accidentally runs into the male lead, Gauss, played by actor Cha Hak-yeon. At that moment, Gauss is bickering and playfully arguing on the street with three of his male friends. These four men actually live together in the same house and share a bond as close as real brothers. What is truly astonishing is that all four of them possess breathtakingly handsome visuals that make people stop and stare. Rather than having rough, hyper-masculine looks, they boast a "pretty boy," idol-like aesthetic that instantly captivates the attention of every woman who walks by.

A Shattered Smartphone Screen and the Worst First Impression

Witnessing this spectacular sight of four flawless, manhwa-like beautiful men gathered together, Eui-joo unconsciously stops in her tracks and stares at them, completely mesmerized. However, Gauss notices her blatant, unwavering gaze and completely misunderstands the situation. Because of his striking looks, he assumes that Eui-joo is secretly taking photos of him without his permission. Expressing his deep annoyance, Gauss approaches her and demands her phone to delete the photos. As a flustered Eui-joo tries to defend herself, a minor physical scuffle breaks out between them. During the struggle, Eui-joo's precious smartphone falls to the ground, shattering its screen into pieces and cementing the absolute worst first impression between the two.

The Ultimate Plot Twist: The Handsome Strangers Are Now Teachers

Carrying the bitter memory of her shattered smartphone screen, Eui-joo goes to school the next day, only to be met with a mind-blowing, jaw-dropping plot twist. The entire school is buzzing with the news that new teachers have arrived. When Eui-joo looks into the faculty office, she realizes that the new teachers are none other than the group of four handsome men, including Gauss, whom she had encountered on the street the day before. As if it wasn't shocking enough that these neighborhood "pretty boys" are actually high school educators, a cruel twist of fate dictates that the prickly Gauss—the very man she fought with—is assigned as the new homeroom teacher for Eui-joo's class.

A School Turned Fan Club and a Brilliant, Rebellious Idea

Being reunited in a strict "teacher and student" hierarchy with her street nemesis throws Eui-joo into a state of deep mental breakdown. From this bizarre coincidence onward, her once-peaceful school life becomes completely tangled and chaotic. As soon as the four flower-boy teachers arrive, the entire school practically transforms into a massive idol fan club, filled with the deafening, enthusiastic cheers of the female students. While every other student goes wild over the teachers' every move, Eui-joo finds the entire situation incredibly annoying and uncomfortable. However, while suffering under her strict homeroom teacher Gauss, a sudden, brilliantly rebellious idea flashes through her mind.

Overnight Success: From Zero Views to the #1 BL Web Novel

Driven by a petty desire for revenge against Gauss and inspired by the flawless visual subjects walking right in front of her, Eui-joo's dormant writer's imagination erupts like a volcano. She immediately begins writing a hardcore BL (Boys' Love) romance web novel featuring the four handsome teachers as the main characters, detailing thrilling and intense same-sex romances between them. Uploaded secretly to relieve her stress, this unconventional novel quickly goes viral among netizens, thanks to her vivid descriptions of their perfect visuals and her remarkably catchy writing style. The unknown writer Eui-joo, who previously struggled to get a single view, wakes up one morning to find that her work has miraculously hit the #1 spot on the overall web novel platform rankings.

Co-Production Details, Release Schedule, and Final Verdict

In reality, Gauss remains completely unaware of his fictional alter-ego and continues to utilize his authority as a homeroom teacher to slightly bully and nitpick Eui-joo, holding onto their past misunderstanding. The thrilling comedy of Eui-joo suffering on the outside while smiling deviously on the inside over her high-rated BL plot makes for a fantastic watch. Currently, the first 4 episodes of The Absolute Value of Romance are available on Coupang Play, with 2 new episodes released every Friday. Notably, this 16-episode series is a global project co-produced with a Singaporean national broadcaster—marking their first-ever direct investment in a Korean drama. While it is highly entertaining, when compared to the heavy-hitting original dramas previously released by Coupang Play, it does feel slightly lacking in terms of directorial tightness and narrative depth, though it remains a fun, breezy binge-watch.
