Ahn Bo Hyun and Cho Jun Young team up as uncle and nephew in Spring Fever.

Spring Fever follows Yun Bom (Lee Joo Bin), a teacher who moves from Seoul to the rural area of Sinsu, carrying scars that run deep, and Seon Jae Gyu (Ahn Bo Hyun), a popular guy in the village with a quirky charm and big heart.

tvN unveiled stills capturing the uncle–nephew dynamics between Seon Jae Gyu (Ahn Bo Hyun) and Seon Han Gyeol (Cho Jun Young). 

Seon Jae Gyu is a troublemaker who keeps the entire village on edge, and Seon Han Gyeol is Jae Gyu's one and only nephew and the top student at Sinsu High School. 

The stills show Jae Gyu, despite his large build and the rough, back-alley-guy vibe, pouring his heart into Han Gyeol's well-being. His goal is to raise Han Gyeol right. Thanks to his tendency to want to do absolutely everything for Han Gyeol, he's even earned the nickname "nephew fool" (i.e., someone foolishly devoted to his nephew).

Meanwhile, Han Gyeol carries a subtle, sophisticated expression on his face as he looks at Jae Gyu, who takes care of him with such meticulous attention. 

Regarding this dynamic, the production team commented, "Ahn Bo Hyun and Cho Joon Young's performances as uncle and nephew were outstanding," adding, "Not only their visuals, but also their solid acting synergy will be a pillar carrying the drama, so we ask for your anticipation."

Spring Fever premieres on January 5. The K-drama will be streaming on Prime Video.
