The budding romance between Ahn Bo-hyun and Lee Joo-bin in tvN’s new series “Spring Fever” is gaining attention as a potential breakout hit. As of its third episode, the drama has already surpassed the 5% viewership mark, a significant milestone in Korean television ratings.

In the upcoming 4th episode airing January 13, Seon Jae-gyu (played by Ahn Bo-hyun) reveals his jealousy as he secretly follows Yoon Bom (Lee Joo-bin) and Choi Yi-joon (Cha Seo-won), highlighting a developing love triangle that has captivated viewers.

Previously, Yoon Bom was relieved to learn the rumor that Seon Jae-gyu was Seon Han-gyeol’s biological father was false. Showing a shift in feelings, she invited Jae-gyu on a date herself. Their sweet interaction ended with Bom affirming his question with a soft “yes,” melting audiences and heightening anticipation.

In episode 4, all eyes will be on the moment the three leads find themselves in the same place. Bom is seen chatting warmly with Yi-joon, while Jae-gyu, clearly uncomfortable and jealous, hides and eavesdrops with a menu covering part of his face. His awkward spying adds humor while sparking curiosity over the reason for Bom and Yi-joon’s meeting.

Choi Yi-joon, once a close friend of Jae-gyu and now an adversary, has returned after a decade with revenge on his mind. He is expected to move from Seoul to Shinsu-eup, adding complexity to the growing romantic tensions. His presence is set to intensify the triangle, building further suspense.

The episode will also showcase Jae-gyu’s “coach moment” as he prepares for the school’s big sports day with fierce determination. Meanwhile, the rivalry with Yi-joon promises to bring more dramatic turns to his relationship with Bom.

Having debuted on January 5 with a strong 4.8% rating, “Spring Fever” has now hit 5.4% by its third episode breaking past the symbolic 5% mark that often separates average from standout dramas. The rapid climb suggests a bright future for this fresh romantic series.
