2026 tvN's first romantic comedy "Spring Fever" released a Highlight video showcasing the all-in-one gift set charm that encompasses comic, romance and healing.
The new tvN Monday-Tuesday drama "Spring Fever", directed by Park Won-guk and written by Kim A-jung, set to premiere Jan. 5, 2026, is a hot pink spring romance that will melt the frozen hearts of Yoon Bom (Lee Joo-been), a teacher chilled by cold winds, and Sun Jae-gyu (Ahn Bo-hyun), a man with a burning heart.
The Highlight video released on the 29th drew attention as unpredictable incidents unfold one after another against the backdrop of the peaceful small town of Shinsu-eup. Sun Jae-gyu, whose personality is like a spark in everything, is a person of interest who stirs up the town with his outlandish actions. Although his rough appearance leads to misunderstandings that he is a dangerously reckless man, he shows a surprising charm as a "nephew fool" who will do anything at the request of his nephew Han-gyeol (Cho Junyoung).
Yoon Bom, an ethics teacher at Shinsu High School who decided to live blandly without any joy or sorrow, reaches a turning point in her life when she becomes entangled with Jae-gyu, the uncle of her student Han-gyeol. She tries to pull herself together, saying, "If I stop you again today, you're not a person but an octopus," but she begins to waver increasingly under Jae-gyu's straightforward courtship.
"Did you say you're going to sleep to me?", "Can you cross the line with me?" and other blunt lines from Jae-gyu and Bom's increasingly entangled reactions foreshadow a romance of stark temperature differences between a fiery man and an icy woman, offering both laughter and fluttering hearts at the same time.
Meanwhile, the appearance of Choi Yi-jun (Cha Seo Won), Jae-gyu's old friend turned rival, heightens the drama's tension. As Yi-jun's story of searching for Jae-gyu for 10 years raises curiosity, the delicate triangle among Jae-gyu, Bom and Yi-jun also evokes interest. In addition, the narrative of Han-gyeol, the unwavering top student at Shinsu High School, and the unfortunate second-place Choi Se-jin (Lee Jaein) is also teased. The main broadcast becomes even more anticipated as it adds a youthful romance in which Se-jin, the only anti-fan displeased with Han-gyeol, and Han-gyeol, who wants to see Se-jin's smiling face without knowing that, stir empathy across multiple generations.
"Spring Fever" is ready to melt viewers' hearts with rich storytelling that will unfold the scenery of a cozy seaside village, realistic humor and warm sensibility. The new tvN Monday-Tuesday drama "Spring Fever," spotlighted as a 2026 anticipated work with a cast and production team known as box-office guarantees, premieres at 8:50 p.m. on Jan. 5, 2026.
