Seo In Guk Had To Wear Makeup On His Burning Red Ears While Kissing BLACKPINK’s Jisoo
Behind the Scenes of a Pivotal Narrative Moment
In the interview, Seo In Guk provided a detailed account of the emotional and physical preparation required for the scene, which serves as a major turning point in the series. According to the actor, the sequence represents a moment of profound realization for the two lead characters. "Jisoo talked about this, too, but there is a moment when the characters reach a kind of awakening, finally deciding to do what their hearts desire," Seo explained. The scene, designed to be the culmination of a slow-burn tension between the protagonists, was intended to evoke a sense of warmth and emotional release.
However, the reality on set was far from the cozy atmosphere depicted on screen. Filming took place during a severe cold snap, a common challenge in South Korean television production, where winter shoots often involve sub-zero temperatures. Seo In Guk noted that the intensity of the cold led to visible physical reactions that threatened the aesthetic of the scene. Specifically, the actor’s ears and hands underwent significant discoloration due to the freezing temperatures, turning a vivid shade of red and, in some instances, a deep purple.
To counteract these effects and ensure that the audience remained focused on the romantic narrative rather than his physical distress, the production’s makeup team had to apply corrective cosmetics to his ears. "If you watch closely, you’ll see that my hands weren’t just red—they were almost purple," Seo recalled. "It was so cold that even my ears turned bright red, and we had to use makeup to cover them up while filming!"

The Physical Toll of Outdoor Winter Filming
The challenges described by Seo In Guk are indicative of the broader logistical difficulties faced by K-Drama production crews during the winter months. South Korean winters are characterized by biting winds and temperatures that frequently drop below -10 degrees Celsius (14 degrees Fahrenheit). For actors, who must often wear stylish but thin "on-screen" attire rather than heavy thermal gear, these conditions can be debilitating.
Seo In Guk described the experience as a "constant battle against the cold," noting that the physiological impact was so severe it affected his cognitive functions on set. "My face was completely frozen, to the point that I don’t even remember how I managed to deliver my lines," he admitted. This level of physical numbing is a frequent occurrence for actors tasked with delivering emotive performances in harsh climates. The ability to maintain character and deliver dialogue convincingly while the body is in a state of mild hypothermic stress is often cited by industry insiders as a testament to an actor’s professionalism and discipline.
In the case of Boyfriend On Demand, the "first kiss" scene was set against a backdrop of falling snow, a classic trope in romantic dramas known as the "Snow Kiss." While these scenes are fan favorites for their aesthetic beauty and symbolic purity, they are notoriously difficult to film. The use of artificial snow machines can add to the moisture in the air, further dropping the perceived temperature for the cast and crew.
Technical Solutions and On-Set Adaptations
To maintain the illusion of a seamless romantic encounter, production teams employ various technical and creative solutions. The use of color-correcting makeup, as mentioned by Seo In Guk, is a standard practice to hide the redness caused by cold or the pallor caused by fatigue. In high-definition broadcasting, even minor skin tone fluctuations can be jarring to the viewer, making the role of the on-set makeup artist crucial during outdoor shoots.
Beyond makeup, crews often utilize portable heaters ("nallos"), heated packs ("hotteok"), and heavy padded coats known as "long paddings" that actors wear between takes. However, once the director calls "action," these comforts are removed. The transition from being bundled in down feathers to standing in a light coat for a multi-hour shoot requires significant mental fortitude.
Furthermore, the cinematography in such scenes often relies on tight framing and specific lighting to mask the breath vapor that becomes visible in the cold. While some directors choose to keep the visible breath to enhance the realism of the winter setting, others prefer a "cleaner" look, which requires actors to hold their breath or use specialized techniques during their lines.
The Synergy Between Seo In Guk and Jisoo
The pairing of Seo In Guk and BLACKPINK’s Jisoo has been a subject of intense public interest since the casting was first announced. Seo In Guk, who rose to fame after winning the inaugural season of the talent show Superstar K, has established himself as a versatile lead in dramas such as Reply 1997, The Smile Has Left Your Eyes, and Doom at Your Service. His reputation for having strong "chemistry" with his female leads made him a highly anticipated partner for Jisoo.
Jisoo, meanwhile, has been carefully navigating her transition from global pop icon to respected actress. Following her debut lead role in the period drama Snowdrop, her involvement in Boyfriend On Demand marks another significant step in her acting career. The collaboration between a seasoned actor-singer like Seo and a global superstar like Jisoo has created high expectations for the drama’s domestic and international performance.

In his interview, Seo In Guk spoke highly of the collaborative process, noting that despite the freezing conditions, both actors were committed to capturing the emotional weight of the "awakening" scene. The mutual dedication required to perform a passionate kiss while physically "frozen" suggests a high level of professional rapport between the two stars.
Broader Implications for the K-Drama Industry
The anecdotes shared by Seo In Guk provide a window into the evolving nature of K-Drama production and the increasing transparency between actors and their fans. In previous decades, the "magic" of television was strictly guarded, with little information released regarding the hardships of filming. However, in the current era of social media and behind-the-scenes content, actors frequently share these "cheeky" or difficult stories, which serves to humanize them and increase fan appreciation for the final product.
From an industry perspective, the success of Boyfriend On Demand is seen as a bellwether for the continued dominance of the "Idol-Actor" model. When high-caliber actors like Seo In Guk are paired with global idols like Jisoo, the resulting projects often see unprecedented international streaming numbers. This synergy helps sustain the global "Hallyu" wave, ensuring that South Korean content remains a staple of international digital platforms.
Moreover, the technical mastery required to turn a physically grueling shoot into a "heart-fluttering" visual experience underscores the expertise of South Korean production crews. The fact that viewers were left with "only the magic of the couple’s first kiss in the snow," unaware of the purple hands and makeup-covered ears, is a victory for the show’s post-production and cinematography departments.

Conclusion and Audience Anticipation
As Boyfriend On Demand continues its run, the revelations regarding the "Snow Kiss" scene are likely to add a layer of intrigue for viewers. Fans often revisit such scenes with a new perspective after learning about the behind-the-scenes challenges, looking for the subtle signs of the cold that Seo In Guk described.
The interview with ELLE Korea serves not only as a promotional tool for the drama but also as a reminder of the craftsmanship involved in television production. By balancing the emotional narrative with the physical realities of the set, Seo In Guk and Jisoo have contributed to the long-standing tradition of iconic K-Drama romances that transcend the environmental conditions of their creation.
Ultimately, the "burning red ears" of Seo In Guk have become a symbol of the dedication required to produce world-class entertainment. As the drama progresses, the focus remains on the "awakening" of the characters, but for the fans, the knowledge of the "constant battle against the cold" adds a profound sense of respect for the actors’ work. Boyfriend On Demand stands as a testament to the fact that while the weather may be freezing, the passion of the performers and the creativity of the crew can create a warmth that resonates across the globe.
