The fifth episode of the new K-drama Spring Fever, titled “Your Uncle is… Not Participating?”, is scheduled to air soon, bringing more of the evolving story between teacher Yoon Bom and the mysterious Sun Jae-gyu. Following a week with no new episode, viewers are waiting to see how the characters deal with the big secrets and emotions from the last episode.
The series follows Yoon Bom, a teacher from Seoul who moves to the small coastal town of Shinsu to escape a painful past. Her quiet life is disrupted by Sun Jae-gyu, a well-known figure in town who is the CEO of JK Power Energy and the guardian of his nephew, Han-gyul. What starts as a clash between two very different people slowly turns into a more complicated connection, especially as rumors spread about Jae-gyu’s true relationship to Han-gyul.
Spring Fever Episode 5 Release Date and Time
Spring Fever Episode 5 was released on Monday, January 19, 2026. This marks a return to the show’s regular schedule after a break following Episode 4, which aired on Tuesday, January 13, 2026.
For international viewers, new episodes are available to stream globally on Amazon Prime Video shortly after they air on Korean television. The drama airs on the Korean network tvN.
- In South Korea: New episodes air on tvN on Mondays and Tuesdays. The local air time is typically in the evening, around 9:00 PM KST.
- For International Viewers: Episodes are available for streaming on Amazon Prime Video. They are usually added to the platform very soon after the Korean broadcast ends. This means viewers in the USA, UK, Canada, Australia, India, and other regions can expect Episode 5 to appear on Prime Video on January 19, 2026.
The series has a total of 12 episodes, so Episode 5 marks the start of the second half of the season.
What Happened Before Episode 5
The first four episodes set up a story full of secrets, misunderstandings, and small moments of connection. Yoon Bom arrived in Shinsu trying to leave her life in Seoul behind. She quickly encountered Sun Jae-gyu, whose bold personality and local reputation immediately caused problems for her.
A major rumor began in Episode 3: people in town started saying that Jae-gyu is not Han-gyul’s uncle, but actually his father. This secret has been a heavy weight on Bom’s mind. The most recent episode, Episode 4, ended with a big confrontation. Bom discovered that Jae-gyu knows secrets about her own past. Feeling exposed and hurt, she built an emotional wall between them.
Determined to clear up the misunderstanding, Jae-gyu brings out his ultimate move to win her back. Will it be enough to thaw Bom’s heart?
This is the tense situation as Episode 5 begins. Jae-gyu is trying to fix things after Bom told him to stay out of her life.
What to Expect in Spring Fever Episode 5
The title of Episode 5 is “Your Uncle is… Not Participating?”. This suggests the episode will focus on the ongoing fallout from Jae-gyu’s secret and his attempts to make things right with Bom.
Viewers can expect the episode to deal with the consequences of Jae-gyu’s “ultimate move” to win Bom back. Will his efforts help, or will they push her further away? The central rumor about Jae-gyu being Han-gyul’s father is also likely to be a key part of the story, possibly moving toward some clarification or creating more complications.
The dynamic between the main characters is at a turning point. Bom saw a softer side of Jae-gyu earlier, which made her reconsider her opinion of him. However, the shock of him knowing her past has made her pull away again. Episode 5 will likely show whether their relationship can recover from this new obstacle.
