From Ice to Intense: Ahn Bo-Hyun & Lee Joo-Bin Bring Heat In ‘Spring Fever’

Spring Fever will premiere on January 5, 2026, on tvN. Ahn Bo-Hyun and Lee Joo Bin star in this romantic drama about frozen hearts thawing in a small town. This 12-episode series, based on Baek Min Ah’s web novel, follows a teacher from Seoul meeting a passionate man with a kind heart. Can spring bring true renewal? Will their contrasting personalities lead to chaos or chemistry? Discover everything about this highly anticipated romance!

The Plot: When a Frozen Heart Lands in Small-Town Sinsu

This is not your average big-city romance. Spring Fever introduces us to Yoon Bom. She is a popular teacher from Seoul. She suddenly transfers to Shinsu High, a rural school in Sinsu. Yoon Bom arrives with her heart completely closed off. Past emotional scars made her build strong walls.

The curious townspeople cannot understand her choice. Why would a teacher of her talent leave Seoul? The small-town anonymity she craves does not exist here. Everyone knows all the details in Sinsu!

This is where the delightful Seon Jae Gyu enters. Ahn Bo-Hyun plays the CEO of JK Power Energy. Jae Gyu is also the uncle of one of Yoon Bom’s students. He might have an intimidating, “tough guy” physique. However, he is surprisingly warm, friendly, and very considerate.

He is basically a cinnamon roll hidden inside a tough exterior. Jae Gyu is completely honest and direct. He does not play games or hide his feelings. His straightforwardness creates hilarious and awkward moments for Yoon Bom. She struggles to deal with someone so transparently kind.

The small-town setting creates wonderful moments for supporting characters. We also have Choi Yi Jun, a lawyer played by Cha Seo Won. Search results suggest Yi Jun is Jae Gyu’s former close friend and now a serious rival. This rivalry is set to heighten the inevitable tension in the love triangle. Yi Jun is described as an outwardly flawless elite lawyer. He will act as a somewhat threatening “catfish man” to Jae Gyu.

Ahn Bo-Hyun and Lee Joo Bin: The Flawless Visual Pairing

This central casting has generated massive online hype. Ahn Bo-Hyun brings his charismatic charm to Seon Jae Gyu. We loved him in hits like My Name and See You In My 19th Life. To add authenticity, he uses a natural Busan dialect. Sources say his dialect and comedic timing made the whole cast laugh. He is perfectly cast as the charging-type, unpredictable man.

Lee Joo Bin takes on the role of Yoon Bom. She is the emotionally wounded teacher seeking healing. Lee Joo Bin excels at playing strong characters with hidden vulnerability. Think of her roles in Queen of Tears and Marry My Husband.

The supporting cast is full of trusted names. Cho Jun Young plays Seon Han Gyeol, Jae Gyu’s nephew. He is the high school’s top student. Jin Kyung has also joined in a significant role. Her addition guarantees a powerful performance.

She is famous for unforgettable roles, such as in Extraordinary Attorney Woo. Bae Jungnam also rounds out this talented lineup. The script reading immediately showed their “steady teamwork.”

Why This TVN Rom-Com is 2026’s Must-Watch

The concept of opposites attracting will never get old. Watching Jae Gyu melt Yoon Bom’s icy heart is pure magic. The rural Sinsu setting makes it feel uniquely fresh. We also love the built-in tension of the premise. She is the instructor of his nephew. That boundary-crossing element adds spice to the romance.

The foundation is built on proven storytelling. Baek Min Ah’s web novel already has a loyal fanbase. That is an instant win for the drama adaptation. Director Park Won Guk’s experience turning web novels into hits is clear. He knows how to enhance emotional moments with great directing. Seriously, who saw that coming?

Even short teasers show off their incredible visual chemistry. Ahn and Lee Joo Bin clearly sparkle together. An AllKpop article highlighted their perfect coupling. The excitement for this hot pink romance is already gripping viewers. It is just the ideal time for a fresh start. The twelve-episode format guarantees no unnecessary filler episodes. Get ready to welcome a new, warm romance into your life!

A Hot Pink Premiere: Dates and Streaming Details

We finally have the firm date for this highly anticipated show. Spring Fever lands on tvN on Sunday, January 5, 2026, at 8:50 PM KST. Plan your viewing schedule immediately. You will find new episodes every Monday and Wednesday.

The series runs until February 10, 2026. Are you worried about watching it internationally? Don’t stress! Amazon Prime Video is streaming the drama worldwide. Each of the 12 episodes is about 70 minutes. That makes them perfect for a cosy evening watch.

The premiere timing is actually quite clever. The drama’s theme is emotional recovery after deep pain. January perfectly matches the idea of a fresh start. Director Park Won Guk mentioned the title refers to “spring lethargy.”

This is that sluggish, tired feeling during a seasonal change. Lee Joo Bin’s character, Yoon Bom, narrates a key line. She says spring was an endless lull until she met her man. That simple quote captures the whole story perfectly.
