tvN’s upcoming Monday–Tuesday drama Spring Fever is set to make its debut, bringing a warm and refreshing romantic comedy to the small screen at the start of 2026. The series centers on a quiet yet emotionally resonant love story that unfolds through everyday encounters rather than exaggerated comedy.

Lee Joo Bin stars as Yoon Bom, an emotionally guarded high school teacher who has withdrawn from others following a life-altering incident. Once admired for her natural charm in Seoul, she relocates to a provincial town, where she lives with a carefully maintained distance from those around her. Opposite her is Ahn Bo Hyun as Seon Jae Gyu, a man whose imposing build and blunt demeanor contrast with his sincere and gentle heart. Dedicated to raising his nephew as his life’s priority, Jae Gyu finds his emotional world unexpectedly shifting after meeting Yoon Bom.

Their relationship gradually stirs the quiet village, driven by the contrast between Jae Gyu’s straightforward honesty and Bom’s reserved nature. Rather than relying on heightened comedy, Spring Fever emphasizes subtle emotional changes and honest interactions, allowing the romance to grow at a natural pace. This balance of warmth and restraint shapes the drama’s inviting tone.

Anticipation is further heightened by the involvement of director Park Won Guk, whose recent projects have drawn attention for their character-focused storytelling. He has described Spring Fever as a story about two people comforting one another while searching for happiness, aiming to deliver laughter alongside moments that feel relatable and sincere. The drama aspires to remain light and heart-fluttering while grounding its emotions in everyday reality.
Spring Fever premieres on January 5 at 8:50 p.m. KST, with viewers eager to see how Ahn Bo Hyun and Lee Joo Bin’s on-screen chemistry brings this gentle romantic comedy to life.
