The tvN Monday-Tuesday drama 'Spring Fever', starring Ahn Bo-hyun and Lee Joo-bin, premiered on January 5. The drama centers around the fateful encounter between teacher Yoon Bom (played by Lee Joo-bin) and male character Seon Jae-kyu (played by Ahn Bo-hyun). According to the viewership rating agency Nielsen Korea on January 6, the first episode of 'Spring Fever' recorded an average nationwide rating of 4.8% and a peak of 6.1% based on paid platforms including cable, IPTV, and satellite. In the metropolitan area, the average was 4.7% and the peak reached 5.8%. Notably, the viewership rating for the target demographic of men and women aged 20-49 on tvN ranked first among all channels, including terrestrial broadcasts, during the same time slot nationwide and in the metropolitan area.

The drama depicts the story of Yoon Bom, who was a popular teacher in Seoul, after she moves to a small town. Yoon Bom wishes to live quietly in the town, but faces difficulties as rumors related to her past spread. She suffers from nightmares every night, leading to an anxious daily life. In this situation, Seon Jae-kyu appears, bringing change to Yoon Bom's routine. Seon Jae-kyu is portrayed as someone who takes charge when it comes to matters related to his nephew, Seon Han-gyeol (played by Jo Jun-young), creating a buzz in the teachers' office simply by his presence.

The first episode featured the initial meeting between Yoon Bom and Seon Jae-kyu as a key scene. Seon Jae-kyu asked Yoon Bom, "Do you send coffee errands to the female teacher?" showcasing his charming twist. The two then meet for the first time while preparing coffee in the teachers' office. Seon Jae-kyu takes control of the atmosphere by directly calling Yoon Bom "beauty."

Later, Yoon Bom unexpectedly encounters Seon Jae-kyu again in front of her house at midnight. Misunderstanding the spicy chicken skewer Seon Jae-kyu was holding as a weapon, Yoon Bom comically runs away in panic. Seon Jae-kyu reveals his tsundere charm when he climbs over the wall using 'backward jumping' to open the door for Yoon Bom. He tells a close aide, "(Yoon Bom) really doesn't recognize me," heightening curiosity about their past.

At the end of the broadcast, there was a scene where Yoon Bom and Seon Jae-kyu meet again for individual parent consultations. While Yoon Bom is dressed brightly and ready, Seon Jae-kyu appears holding a money tree pot as tall as himself, making his presence felt. He calls Yoon Bom "Bom-ah~" in a casual manner, adding to the tension.

'Spring Fever' is a drama set in a seaside town, blending cheerful character play, which has captured viewers' attention since its first airing. Anticipation is growing for how the relationship between the two main characters will develop. Episode 2 will air on January 6 at 8:50 PM.
