Absolute Value of Romance (2026)
로맨스의 절대값 (Romaenseuui Jeoldaegabt)
Genre: Comedy, Youth, Drama
Director: Lee Tae Gon
For anyone avoiding Absolute Value of Romance because of assumptions about an inappropriate teacher student romance, here is an important clarification:
THERE IS NO TEACHER STUDENT ROMANCE.
That distinction matters because this drama could have easily gone in an uncomfortable direction. Instead, Absolute Value of Romance becomes one of the funniest, most charming, and unexpectedly heartfelt K dramas of 2026.
What initially sounds like an absurd premise, a high school student secretly writing adults only BL web novels inspired by her handsome teachers, slowly transforms into a genuinely touching coming of age story about awkward adolescence, imagination, embarrassing first crushes, and growing up.
Somewhere between the chaos, comedy, and cringe, this drama quietly sneaks up on viewers and reveals itself to be an absolute gem.
Plot: A Teenager, Four Teachers, and Way Too Much Imagination
The story follows Yeo Eui Ju (Kim Hyang Gi), an ordinary high school student who is average in every possible way and intentionally tries to keep a low profile at school. However, once the sun goes down, she leads a secret double life as a writer of daring adults only BL web novels online.
Unfortunately, despite her enthusiasm, almost nobody reads them.
Though observant and empathetic, Eui Ju is hilariously hopeless when it comes to understanding romance in real life. Everything changes when four incredibly handsome men move into the neighborhood and later turn out to be the newest teachers at her school.
Naturally, Eui Ju’s imagination spirals completely out of control.
Inspired by their personalities, interactions, and endless accidental misunderstandings, she begins using them as inspiration for a BL novel, shamelessly borrowing real life scenarios and even bits of dialogue.
The result?
Absolute chaos.
And it is genuinely hilarious.
Every scene filtered through Eui Ju’s imagination becomes wildly overdramatic and absurd in the funniest possible way. It has been a long time since a K drama delivered this level of laugh out loud comedy.
Meet the Chaotic Dream Team of Teachers
What makes Absolute Value of Romance especially entertaining is how distinct and lovable the four teachers are.
Ga U Su (Cha Hak Yeon / N)
Ga U Su, played by Cha Hak Yeon from VIXX, is the school’s cold, strict, and intimidating math teacher, but underneath that icy exterior lies someone who deeply cares about his students.
A mathematical prodigy from a prestigious family of renowned mathematicians, U Su once planned to study abroad before a life changing incident nearly cost him his eyesight, forcing him to abandon those plans.
Despite constantly bickering with students, especially Eui Ju, he consistently acts in their best interest.
It also helps that Cha Hak Yeon looks exceptionally charismatic in this role, making Ga U Su all the more memorable.
For mathematics enthusiasts, the name pun is especially delightful. “Ga U Su” is clearly a clever reference to the mathematician Gauss, a small but brilliant touch that adds extra charm to the drama.
No Da Ju (Kim Jae Hyun)
No Da Ju is the school’s Japanese language teacher and easily one of the funniest characters in the drama.
Born into a wealthy family, he is a gifted polyglot fluent in multiple languages and has been U Su’s longtime friend. The two constantly argue and tease each other, creating some genuinely entertaining moments.
Da Ju brings a cheeky, playful energy to every scene and never misses an opportunity to joke around with students.
Jung Gi Jeon (DEMIAN)
Former luge athlete Jung Gi Jeon had to retire after suffering an injury, eventually becoming the school’s warmhearted sports teacher.
He is sweet, slightly clumsy, endlessly supportive, and probably the kindest teacher imaginable. Gi Jeon quickly notices Eui Ju’s natural talent for running and begins encouraging her athletic abilities, seeing potential in her that she never recognized herself.
Honestly, he may be one of the sweetest teachers in recent K drama history.
Yun Dong Ju (Kim Dong Kyu)
The Korean literature teacher Yun Dong Ju is perhaps the softest presence in the series.
Warmhearted, respectful, and endlessly patient, he treats students with kindness, consistently speaks politely using honorifics, and somehow never loses his temper.
He feels like the kind of teacher every student wishes they had.
Comedy First, Nostalgia Second
One of the drama’s greatest strengths is how perfectly it captures the beautiful absurdity of being a teenager.
Watching Absolute Value of Romance often feels like opening an old yearbook and cringing at younger memories, but affectionately.
It captures that awkward phase of life where every emotion feels ten times bigger than it actually is. Every crush feels like destiny. Every secret feels life changing. Every embarrassing mistake feels impossible to recover from.
Eui Ju embodies this perfectly.
She overthinks every interaction, panics whenever things go wrong, and constantly spirals into dramatic internal monologues.
And somehow, all of it feels painfully relatable.
Even her much discussed hairstyle, which admittedly looked questionable in promotional material, eventually becomes part of her charm. If anything, it amplifies the goofy, chaotic energy of her character.
The drama also shines through small details and wordplay. One particularly funny example is Eui Ju’s best friend Choi Go Ya, whose name sounds like “최고야” (choegoya), meaning “the best” in Korean.
Whether intentional or not, these tiny touches give the drama even more personality.
Addressing the Biggest Misconception
The biggest surprise, and perhaps the drama’s smartest decision, is how responsibly it handles its premise.
Yes, Eui Ju develops feelings for Ga U Su.
But that is exactly what it remains:
A crush.
An innocent, awkward, very teenage first crush.
The drama never romanticizes inappropriate boundaries. From U Su’s side, things remain remarkably clear throughout. He never reciprocates Eui Ju’s feelings, never encourages them, and never crosses any professional lines.
He consistently treats her as his student.
That distinction is exactly what makes the drama work.
Rather than forcing romance where it should not exist, the story acknowledges something many people experience growing up: sometimes a first love is simply admiration from afar, something intense in the moment but temporary in hindsight.
That emotional maturity becomes one of the show’s greatest strengths.
A Surprisingly Strong Ending
One of the biggest questions surrounding the drama is how it would resolve its central emotional tension.
Would it suddenly force romance through a time skip?
Would it leave everything unresolved?
Would it somehow ruin the tone?
Thankfully, Absolute Value of Romance chooses the smartest and most emotionally satisfying route possible.
Instead of turning Eui Ju’s feelings into some grand romance, the drama treats them for what they are: first love, puppy love, a meaningful but fleeting experience.
The ending acknowledges the sincerity of her emotions without pretending they are meant to last forever.
The snow symbolism during the final stretch adds just enough emotional softness to make everything land beautifully.

Final Thoughts
What begins with very low expectations quickly transforms into an unexpectedly delightful viewing experience.
At a time when many K dramas have felt repetitive or disappointing, Absolute Value of Romance feels refreshingly different.
Although the second half occasionally shifts away from the stronger comedic momentum of the first half, the series remains entertaining from beginning to end.
Funny, comforting, chaotic, nostalgic, and unexpectedly heartfelt, Absolute Value of Romance reminds viewers that adolescence may have been embarrassing and ridiculous, but it was also undeniably precious.
For anyone looking for something lighthearted, funny, and genuinely enjoyable, this drama deserves a chance.
Rating: 9/10. One of 2026’s most unexpectedly delightful hidden gems.
