Belonging to the romantic comedy genre, "Spring Fever" (temporary translation: Hidden Spring Flower) tells the love story of Yoon Bom (Lee Joo Bin) - a cold high school teacher and Seon Jae Gyu (Ahn Bo Hyun) - a passionate guy with a grandson studying at Bom's school.
According to director Park Won Guk, the character Jae Gyu "breaks the stereotypes of ordinary TV series and expresses the true nature of coolness", promising to bring the audience a simple, warm but also funny love story.
In this project, in addition to having to gain 5kg for the role, Ahn Bo Hyun is extremely excited to use the local language. The actor from Busan (Korea) is confident that he will do well when performing Gyeongsang's local accent on screen. "I have always wanted to act in a local accent, and this film has given me the opportunity to develop my'secret weapon'.
Also according to the male actor, "Spring Fever" has completely different colors compared to the movies he has performed before, so if he acts well, there will be many audiences watching the work.
Meanwhile, director Park - who was successful with the movie "You Let Me Get Married" (2024, highest viewership rate 12%) set a goal that "Spring Fever" will receive more love from the audience, greater than "You Let Me Get Married" received before.
In addition to the plot and actors, "Spring Fever" is expected to be set in Pohang, North Gyeongsang province (South Korea) - a coastal city that has attracted tourists after the success of the movie "Cha Cha Cha Village Dance" (2021, Shin Min Ah/Kim Seon Ho starring).
Previously, the female lead Lee Joo Bin said that filming in a coastal city made her feel like "traveling with everyone", and expected the audience to also feel the warmth and beautiful setting when the movie airs. In addition, this is also a project where she can show her diverse acting ability.
The movie "Spring Fever" is 12 episodes long and is scheduled to air on January 5, 2026, after Lee Jung Jae and Lim Ji Yeon's movie "Lot ho ga kho ua" ends.
