When Seoul's coldest teacher meets a small-town firecracker, sparks don't just fly—they ignite an entire village. Fresh from their electric press conference in Seoul, the cast and crew of Spring Fever just gave us every reason to clear our Monday and Tuesday nights. From the director of Marry My Husband, comes a rom-com that promises to thaw even the iciest of hearts. Lee Joo-been stars as Yoon Bom, a high school teacher whose frosty demeanor hides layers of complexity, while Ahn Bo-hyun brings the heat as Sun Jae-gyu, a passionate force of nature who's about to turn her world upside down.

Premiering January 5 with weekly episodes streaming exclusively on Prime Video across 240 countries and territories, here's why Spring Fever deserves a spot on your must-watch list:After shattering ratings records with Marry My Husband, Director Park Won-kook could have played it safe. Instead, he's doubling down on what made audiences fall in love in the first place—authentic emotion.
For Ahn Bo-hyun, Sun Jae-gyu represented uncharted territory. "He's completely different from any characters I've played before. I'd been dying to work on a project where I could use a dialect," he shared. His commitment? Questionable fashion choices in the series (his words, not ours), serious muscle gains, and staying true to a character unlike any romantic lead we've seen.
Lee Joo-been was equally captivated by her role's complexity. "Yoon Bom isn't a character you see in series these days. She transforms drastically from beginning to end—not just her personality, but her entire physical appearance. Her clothes, makeup, even her hair length evolve throughout the story."

Translation? These aren't static characters going through the rom-com motions. They're living, breathing, constantly surprising humans you'll actually want to root for.
