The upcoming tvN Monday-Tuesday drama ‘Spring Fever’ has set its premiere date for January 5, 2026, and has unveiled captivating character posters featuring Ahn Bo-hyun and Lee Joo-bin, heightening anticipation.

‘Spring Fever’ tells the story of Yoon Bom (Lee Joo-bin), a teacher in the chilly winds, and Seon Jae-gyu (Ahn Bo-hyun), a man with a burning heart. The romantic comedy promises to melt away frozen hearts with a vibrant pink romance.

The character posters, released today (17th), showcase the contrasting charms of the two leads. Seon Jae-gyu exudes an overwhelming presence with his form-fitting short-sleeved t-shirt and visible tattoos, while his appearance at the classroom door is accompanied by the dialect line, “Wow, are you scared you’ll fall for me?”, hinting at his 'countryside femme fatale, straight-shooter' character.

On the other hand, Yoon Bom, leaning against the classroom window, appears surprised by Jae-gyu’s relentless pursuit. The phrase, “Mr. Seon Jae-gyu, don’t cross the line anymore,” suggests that her frozen emotions are beginning to stir. The anticipation builds as to whether Jae-gyu’s passionate love can melt Bom’s heart, with her wide-eyed expression adding to the delicate flutter of excitement.

Ahn Bo-hyun is set to bring a fresh kind of fun to viewers’ screens with his powerful, straightforward character delivering a robust dialect, and his heartwarming visual chemistry with Lee Joo-bin is already capturing the audience’s attention.

‘Spring Fever’ is a collaboration between director Park Won-gook, who holds the record for the highest viewership ratings for a tvN Monday-Tuesday drama with ‘Marry My Husband,’ and writer Kim A-jeong, and is expected to ignite a romantic comedy craze in 2026.

Upon the release of the news, netizens expressed their excitement, commenting, 'Ahn Bo-hyun and Lee Joo-bin’s visuals are insane! They really look like they stepped out of a comic book,' 'A guy who speaks dialect and is a straight-shooter, I'm already excited,' and 'How can I wait until 2026? I want to watch it soon!' showing their high anticipation for the drama.
