The tvN romantic comedy drama "Spring Fever" is releasing its fourth OST. The production team announced, "On the 19th at 12 PM, OST Part 4 'Staying in Your Season,' featuring vocals by Jaeyeon, will be released on various music platforms."

"Spring Fever" centers around the romance between teacher Yoon Bom (played by Lee Joo-bin) and male Seon Jae-gyu (played by Ahn Bo-hyun). Yoon Bom is portrayed as a voluntary outsider, while Seon Jae-gyu is depicted as a character with a strong personality. Their relationship offers viewers a unique thrill through subtle chemistry.

The fourth OST, "Staying in Your Season," is a song that metaphorically expresses the time of love and parting through the seasons. Jaeyeon's delicate vocals calmly build up the emotion of longing, adding a deep resonance to the drama's narrative. Jaeyeon gained attention in 2019 with the ballad version of the OST "In the Shaking Flowers, I Smelled Your Shampoo" from the drama "Melo Is My Nature," and has since been actively involved in OSTs for various works.

In this song, "Staying in Your Season," Jaeyeon's charming voice maximizes the lyrical atmosphere of the track, providing a deep sense of immersion.

The drama "Spring Fever" airs every Monday and Tuesday at 8:50 PM. OST Part 4, Jaeyeon's "Staying in Your Season," will be released on music platforms at 12 PM on the 19th.
