IU dedicates 'soulmate song' to Yoo In-na, celebrating 15-year bond
Singer IU honors her longtime friend Yoo In-na with a heartfelt video and the new song 'Dear my crazy soulmate,' celebrating their 15-year friendship.
Singer IU has expressed her unwavering affection for actress Yoo In-na by releasing a video filled with shared memories and a song she wrote specifically for her, celebrating a friendship that has spanned over 15 years. While many connections formed through professional projects in the entertainment industry naturally fade over time, the two are drawing attention once again as quintessential "celebrity best friends" who have maintained a private bond for well over a decade.

On the 15th, IU posted a video to her personal account featuring a compilation of photos, captioned "Sure YOO IN NA we best soulmate" alongside the phrase "Dear my crazy soulmate."
The video captures the journey IU and Yoo In-na have taken together, ranging from recent moments to their youthful past. Private, everyday snapshots—such as photos from trips, visits to each other's events to show support, and playful selfies—appear in succession, offering a glimpse into a relationship that goes far beyond official professional activities.
The video includes rare, previously unreleased images, such as photos seemingly taken during a trip to Italy about 10 years ago. Beyond merely showcasing their closeness, the video compresses the trajectory of a relationship built over a long period into a single visual tribute.
The background music intensifies the emotional impact. As "Dear my crazy soulmate," a song IU personally created for Yoo In-na, plays, subtitles display lyrics such as "My dream is for us to become two weird grandmas together," "What matters, FAKE, REAL," "When you laugh seeing me being playful," "Until the world eventually gives up on us," "Even at the moment the world eventually collapses," and "Just the two of us like this."
The term "soulmate" transcends being a mere descriptor for a close friend; it symbolizes a relationship where two people have shared their lives and formed a deep emotional bond. IU's message—imagining a future where she grows old with Yoo In-na and expressing a desire to remain close even if the world changes or collapses—demonstrates that their friendship transcends a temporary connection made through television.
On the 10th, IU released her new digital single "From This Star." The single features two title tracks, "From This Star" and "Dear my crazy soulmate," for both of which IU participated in writing the lyrics.
"Dear my crazy soulmate" is clearly a tribute to Yoo In-na from its very title. IU even personally wrote "To Yoo In-na" in the description box of the song's music video. Specifying a particular person as the recipient in a musical work intended for the public highlights both the creative intent and the intimate nature of their bond.
The connection between the two began in 2010 on the SBS variety program "Heroes." At the time, IU was a rookie singer in her late teens, while Yoo In-na was an actress expanding her public recognition. Despite an 11-year age difference, the two quickly grew close and maintained their relationship long after the program ended.

Their friendship has followed a pattern distinct from the typical "program-based connections" often seen in the industry. Beyond appearing on the same broadcasts, they have been consistently seen visiting each other's schedules, traveling together, and sharing private time. Even as IU's musical career and Yoo In-na's acting career followed different paths, their bond remained constant.
Yoo In-na has been frequently mentioned by IU as being more than just a colleague. Whenever IU publicly expresses her affection for Yoo In-na, the relationship draws significant interest from fans. This is due to their rare continuity in the pop culture industry, as they have remained close as individuals regardless of their professional identities.
IU has grown into one of the most prominent artists in Korean pop music, expanding her reach through singing, acting, composing, and songwriting. Since her debut in 2008, she has built a massive creative world with hits such as "Good Day," "You & I," "Through the Night," "Palette," and "Lilac."
Yoo In-na has also established a unique presence through acting and her work as a radio DJ. Known for her distinct voice and hosting abilities, she has connected deeply with listeners on the radio while solidifying her acting career across genres ranging from romantic comedies to melodramas.
What makes their relationship particularly notable is that the depth of their friendship has been maintained even as their professional fields do not overlap. Unlike many industry networks that rely on shared projects, they have maintained a private relationship while their respective careers expanded independently.
The video serves as a visual summary of those years. From their younger days to their adult lives spent traveling and attending events together, the footage proves that "15 years" is not just a number, but a testament to a cumulative, lifelong bond.
IU's message through her new song can be read as a tribute to human connection that outlasts the fleeting nature of celebrity life. While a star's life is constantly subject to the public eye, the existence of someone with whom they can share their private self makes their relationship truly special.
IU's wish to "become two weird grandmas together" encapsulates the essence of this friendship: a sincere, slightly whimsical promise to remain close regardless of age, popularity, or the passage of time.
Ultimately, "Dear my crazy soulmate" differs from the music IU typically performs for her fans. It is a private tribute to the person who has stood by her side for a long time. By pairing the song with 15 years of accumulated memories, IU has completed a beautiful "chronicle of friendship" with Yoo In-na.
