Listen up, my fellow drama degenerates: if you’ve ever stayed up until 3 AM writing self-indulgent fanfiction and then prayed no one in your real life ever discovered it, Absolute Value of Romance (로맨스의 절대값) is basically your worst nightmare and wildest dream rolled into one glittery, chaotic package. This 2026 Coupang Play/Prime Video gem is a 16-episode teen rom-com that takes the “write what you know” advice way too literally and runs it straight into a wall of handsome teachers.
Starring the eternally adorable Kim Hyang-gi as our secret BL novelist queen, with a squad of unfairly hot male leads including Cha Hak-yeon, Kim Jae-hyun, Son Jeong-hyeok (DEMIAN), and Kim Dong-kyu, it’s like someone took every “teacher-student” trope, added a generous scoop of BL fantasy, and then shook it violently until pure comedic absurdity spilled out. I binged this right after it wrapped in late May, and honey, I was cackling, cringing, and kicking my feet like a teenager again. It’s silly, spicy in the most harmless way, and surprisingly heartfelt. Let’s spill the tea.
The Plot: When Your Fanfic Becomes Reality TV
Yeo Eui-ju (Kim Hyang-gi) is your average high school sophomore — quiet, unremarkable, trying to survive without drawing attention. By night? She’s a struggling web novel writer pumping out BL romance stories that barely get two views per chapter. Girl is out here writing slow-burn tension between imaginary men while eating instant ramyeon and dodging her classmates’ drama.
Enter the four new teachers who look like they stepped out of a manhwa: icy math genius Ga Woo-su (Cha Hak-yeon), the cold one with a tragic backstory and resting “I could ruin your GPA” face; lively and mischievous Japanese teacher Noh Da-ju (Kim Jae-hyun), who flirts with chaos; gruff PE teacher Jung Gi-jeon (Son Jeong-hyeok), all muscles and tough love; and gentle literature teacher Yoon Dong-ju (Kim Dong-kyu), the soft-spoken one who makes you want to write poetry (or more BL).
Eui-ju takes one look at this walking thirst trap squad and decides: “Perfect inspiration.” She writes them into her new novel as the ultimate BL ensemble, and boom — it blows up overnight. Her secret life is thriving until math teacher Woo-su (her literal academic nemesis) discovers her pen name and the fact that she’s been turning him and his colleagues into fictional boyfriends. Cue absolute pandemonium: blackmail attempts, awkward hallway stares, fictional scenes bleeding into real life, and Eui-ju trying desperately not to expose her delulu brain to the entire school.
It’s Secret Garden body-swap levels of “how did we get here?” mixed with meta commentary on fandom, creativity, and the terrifying gap between imagination and reality. No heavy makjang trauma — just peak teenage mortification.
Kim Hyang-gi as Yeo Eui-ju: Our Relatable Delulu Queen
Kim Hyang-gi is perfection here. She nails the duality of shy student by day and unhinged BL enthusiast by night. Watching her spiral every time one of her “characters” does something that matches her fic is comedy gold. She brings this wide-eyed innocence mixed with savage inner monologue energy that makes you root for her even when she’s making the most unhinged choices.
Her panic faces? Iconic. Her determination to keep writing despite the chaos? Relatable. She carries the show’s heart and humor without ever tipping into annoying territory. You’ll be yelling “girl, delete the chapter!” at your screen while secretly cheering her on.
The Teacher Squad: Four Flavors of Handsome Chaos
Cha Hak-yeon as Ga Woo-su serves serious cold tsundere realness. That man can glare while solving differential equations and still make hearts race. The slow thawing as he gets tangled in Eui-ju’s web is delicious — equal parts frustrated and reluctantly charmed.
Kim Jae-hyun brings playful mischief as Da-ju, the one who seems to know exactly how chaotic this all is and leans in anyway. Son Jeong-hyeok’s Gi-jeon is the tough exterior with a golden retriever heart, especially when spotting Eui-ju’s hidden athletic talent. And Kim Dong-kyu’s gentle Dong-ju rounds out the group with calm, thoughtful vibes that contrast beautifully with the others.
The chemistry among the four teachers is surprisingly fun — they bounce off each other like a found family of hot messes. And the tension (platonic and otherwise) with Eui-ju never crosses into creepy territory; the show stays firmly in “awkward comedy” lane.
Humor, Sass & Secondhand Embarrassment Overload
This drama is funny. The kind of funny where you snort-laugh and then immediately hide your face because the cringe is too real. Eui-ju’s internal monologues while staring at her teachers? Peak sass. The moments when her novel scenes start mirroring real life (hello, dramatic rain confessions and lingering eye contact) will have you dying.
It roasts fandom culture, creative block, high school hierarchies, and the absurdity of teenage hormones with zero mercy but plenty of affection. There are running gags about her low-viewer days, frantic chapter deletions, and the teachers slowly realizing they’re starring in someone’s delulu romance. The BL novel excerpts we see are gloriously over-the-top, and the show isn’t afraid to poke fun at the tropes while loving them.
Heartwarming Bits Hidden Under the Sass
For all the chaos, it sneaks in some gentle coming-of-age wisdom. Eui-ju learns to own her creativity, face her fears, and realize that real connections are messier (and better) than fiction. The teachers get their own mini-arcs dealing with past wounds, expectations, and what it means to inspire the next generation. It’s surprisingly empathetic toward teens navigating identity, pressure, and first crushes — without ever getting preachy.
The Spicy (But Safe) Vibes
It’s spicy in that delicious “will they won’t they” tension way, not explicit. The slow-burn awkwardness between Eui-ju and certain teachers crackles with chemistry, but the show knows its audience and keeps things light, fun, and age-appropriate while still delivering butterflies. The BL elements add an extra layer of meta-flavor without making it a full BL drama.
Small Gripes From Your Sassy Reviewer
Not everything’s perfect, darling. Some episodes lean a bit repetitive with the “secret almost exposed!” formula, and a couple of side characters could’ve used more depth. The ending (while sweet) left some fans wanting a touch more closure on certain threads. Pacing is quick and breezy, which is great for bingeing but might leave you wishing for deeper moments in the back half.
Final Verdict: 8.8/10 – Your New Chaotic Comfort Watch
Absolute Value of Romance is the hilarious, heart-fluttering escape you didn’t know you needed. It’s self-aware, ridiculously entertaining, and packed with charm. Kim Hyang-gi leads a stellar cast through one of the most fun high school premises in recent years — equal parts cringe comedy, gentle growth, and “what if my fanfic came to life?” fantasy.
If you love meta rom-coms, teacher squads that shouldn’t be this attractive, strong female leads with secret talents, and dramas that embrace the messiness of creativity and crushes, stream this immediately on Prime Video or Coupang Play. It’s light enough for a quick binge but sticky enough that you’ll be quoting lines for weeks.
Clear your schedule, silence your notifications, and prepare for maximum secondhand embarrassment. Eui-ju would want you to live your delulu truth — just maybe don’t base your next novel on your real-life coworkers, okay?
