Hi-Fi Unicorn Adds Their Voice Once Again to Spring of the Four Seasons – Sweet OST “I, You, We” Releases Today (June 4)

The rising band Hi-Fi Un!corn is back to enchant K-drama fans, lending their signature sound to the OST Part 6 of SBS’s hit youth drama Spring of the Four Seasons. Their new track, “I, You, We”, drops today, June 4 at 6 PM KST, across major music platforms.

Following their previous contribution with the upbeat “My Head is Fever”, Hi-Fi Un!corn once again adds emotional depth to the series’ soundtrack. “I, You, We” is a medium-tempo pop ballad that blends acoustic guitar with heartfelt melodies, painting a picture of love blossoming from familiarity—almost like fate. The lyrics reflect a moment of realization, like déjà vu, when two people recognize their feelings through each other’s comforting presence.

The song beautifully complements the evolving romance between lead characters Sa-gye (played by Ha Yu-jun) and Kim Bom (played by Park Ji-hoo), amplifying the emotion and chemistry that fans have come to adore.

Hi-Fi Un!corn—featuring the expressive vocals of Um Tae-min and Fukushima Shuto—has been gaining traction with performances both in Korea and abroad. Their unique sound, blending freshness with emotional sensitivity, is once again expected to heighten viewers’ immersion in the series.

Spring of the Four Seasons is a youth music romance drama following the story of Sa-gye, a star in a top K-pop band who gets unexpectedly removed from the group. As he begins a new chapter in college, he meets Kim Bom in a twist of fate that sets the stage for a heartfelt journey of growth, music, and love. The drama has been receiving strong buzz, especially after its pivotal 5th episode, and continues to charm audiences with its fast-paced plot and standout musical moments.

Tune in to Spring of the Four Seasons every Wednesday at 10:40 PM KST on SBS. The 6th episode airs tonight (June 4), and with it, fans can now enjoy the full experience of “I, You, We”, available now on streaming platforms.
