IU and Shim Dal-gi show incredible chemistry in new MV
Actress Shim Dal-gi delivers a powerful performance alongside IU in the new music video for 'Dear my crazy soulmate,' featuring a star-studded ensemble.
Actress Shim Dal-gi has left a short but powerful impression in IU's new music video. Portraying a police officer, Shim displayed her unique acting skills through natural chemistry with IU, while also serving as a key pillar in the music video's narrative by joining a cross-generational cast that includes Kim Young-ok and Na Moon-hee.

On the afternoon of the 10th, Shim appeared alongside IU as a police officer in the music video for "Dear my crazy soulmate," a double title track from IU's digital single "From This Star." Since this is IU's first new release approximately one year after "Bye, Summer" last September, attention has focused not only on the music release but also on the casting and narrative of the music video.
In the music video, IU and Shim appear as police officers living out their ordinary daily lives. The moment the window of the police station suddenly breaks, the two react with almost simultaneous expressions of surprise and gestures, accepting the situation. The scene where they exchange similar reactions functions as a device to immediately showcase the chemistry between the two actresses. Rather than a simple lead and supporting role relationship, the "tiki-taka" (playful banter) created by them reacting to each other's acting within a single scene forms the pleasant rhythm of the work.
Afterward, the atmosphere shifts abruptly as Kim Young-ok appears beyond the broken window. Kim leaves a strong impression appearing in handcuffs, while Shim acts as the link in the drama as a police officer following the flow of the incident alongside IU. With Na Moon-hee joining in, a unique ensemble is completed where young and veteran actors intersect within a single work.
An especially interesting aspect of this casting is that instead of simply listing famous actors, IU utilized their individual personalities and relationships. IU and Shim share the same professional setting as police officers to show the unique rapport of colleagues, while Kim Young-ok and Na Moon-hee add a texture of time to the onscreen relationship as actors who have actually maintained a connection for many years. It is a convergence of different layers—youth and experience, singer and actor—within one short video.
Shim's strengths are also clearly revealed in this music video. Rather than relying on exaggerated expressions or lines, she has built her characters by focusing on momentary changes in facial expressions, gestures, and reacting to her co-stars. Even in this instance, through a short scene showing similar reactions to IU, she effectively conveyed the bewilderment of the police character and the comedic emotion of the situation.
Born in 1999, Shim has built a filmography moving between independent films, commercial films, and dramas after her debut in the 2018 film "Dong-a." She has portrayed characters with strong personalities in films such as "The Dream Songs," "Samjin Company English Class," "Mala," "Life Is Beautiful," "Killing Romance," and "She Died," and has expanded her range of genres and characters in dramas like "Save Me 2," "Hospital Playlist," "The School Nurse Files," "Shadow Beauty," "Juvenile Justice," and "Our Blues."
In particular, Shim has been evaluated as an actress who does not confine herself to a single image. Moving widely from works dealing with the realistic anxieties and cracks of youth to dramas and films with strong genre colors, she has accumulated presence by giving a unique texture to her characters regardless of whether she is a lead.
This meeting with IU is an example showing that Shim's strengths can also work within popular music content. In this single, IU presented "From This Star" and "Dear my crazy soulmate" as double title tracks, both of which she wrote herself. This single also serves as a preview of tracks that will be included in her upcoming 6th full-length album.
"Dear my crazy soulmate" is a song that puts the relationship of a "soulmate" at the forefront from its title. Since IU's music goes beyond simple romantic feelings to talk about friendship, solidarity shared with a specific person, and relationships that accept each other's quirks as they are, the music video also takes the relationship and chemistry between characters as a major axis. In fact, as it has been known that the song contains a message for Yoo In-na, IU's unique view of relationships—not limiting the concept of "soulmate" to romance—is being highlighted.
In that context, Shim's police character functions as a "colleague" who experiences the incident alongside IU and as a character who drives the story. If Kim Young-ok and Na Moon-hee are symbols of a relationship that has shared time, IU and Shim show the relationship of the younger generation sharing reactions within a momentary incident. It draws attention as a casting that compresses various layers of generations and relationships into a single music video.
Shim will continue to expand her range in upcoming projects. Disney+ "Moving Season 2" tells the story of superpowered individuals facing new crises following the "Jungwon High School incident," with Kang Full returning as screenwriter and Kim Seong-hun directing. With the addition of new actors alongside existing leads like Ryu Seung Ryong, Han Hyo-joo, and Zo In Sung, interest is growing in Shim's future moves.
In IU's music video, Shim's screen time is not long. However, considering that music videos must compress narrative and character in a short time, her ability to make an impression through chemistry with her co-star serves as a measure of her competitiveness as an actress.
Ultimately, the highlight of "Dear my crazy soulmate" is not just IU's new song. It is the way the playful police duo of IU and Shim, alongside the seasoned presence of Kim Young-ok and Na Moon-hee, intersect to create an ensemble that feels like a short film, transcending the music itself. Attention is now focused on which new face Shim will reveal in her future works.
