This is the K-drama premise nobody knew they needed — and now that it’s here, it’s impossible to look away. “Absolute Value of Romance” tells the story of high school student Yeo Eui Ju (Kim Hyang Gi), who secretly writes a BL novel featuring her handsome teachers as the main characters — until she starts running into them in real life at the most unexpected moments, sending her once-peaceful school life into delightful chaos.
Absolute Value of Romance Full Cast — Teachers vs. Their BL Alter Egos
| Actor | Real Teacher | BL Novel Character |
|---|---|---|
| Cha Hak Yeon | Ga Woo Su — sharp math teacher | “Ju Si On” — the obsessive one |
| Kim Jae Hyun | Noh Da Ju — multilingual teacher | “Han Jae Min” — the wealthy one |
| Sohn Jeong Hyuck | Jung Gi Jeon — PE teacher | “Kang Tae Ha” — the bold one |
| Kim Dong Gyu | Yoon Dong Ju — Korean language teacher | “Choi Yoon” — the soft-hearted one |
What the New Teaser Reveals
The newly released character teaser introduces each teacher one by one — from Ga Woo Su’s sharp refusal to tolerate Yeo Eui Ju’s antics, to Noh Da Ju coolly telling her “I know everything,” to PE teacher Jung Gi Jeon cheekily asking her, “Blink twice if you’re being threatened by the math teacher.” The energy is gloriously unhinged.
In her imagination, as the fictional BL characters fight over “Choi Yoon,” Yeo Eui Ju yells “Cut!” — snapping herself out of her daydream and resolving to make the best possible use of her teachers as novel inspiration. Relatable, honestly.
Boys’ Love (BL) storytelling has grown into a mainstream force in Korean pop culture, and “Absolute Value of Romance” cleverly places it at the heart of a coming-of-age school comedy — a fresh and self-aware spin that feels very 2026.
