Absolute Value of Romance

Yeo Ui-Ju (Kim Hyang-Gi) is a high school student leading a secret double life—by day, she’s an ordinary student, but by night, she writes romance novels inspired by charming teachers. Her fictional world starts to blur with reality when she unexpectedly crosses paths with four striking teachers who resemble the very characters she creates, turning her school life into a whirlwind of chaos and confusion.

Among them is Ga Wu-Su (Cha Hak-Yeon), a brilliant math teacher with an IQ of 156 and a member of Mensa, known for his cold demeanor and rare smiles. No Da-Ju (Kim Jae-Hyun), the Japanese language teacher, stands in contrast with his cheerful and outgoing personality. Jung Gi-Jeon (Sohn Jeong-Hyuck), the PE teacher, exudes a strong and masculine presence, while Yun Dong-Ju (Kim Dong-Kyu), the Korean language teacher, is warm, gentle, and kind-hearted.
