Si-An and Jun-Seo: Is The Single’s Inferno Duo Still Together?

Having served in the Korean Navy Special Warfare Flotilla (UDT/SEAL) for several years before being honorably discharged in 2019, Yuk Jun-Seo admittedly had trouble adjusting to civilian life. This included the world of dating too, which is just part of why he decided to join the cast of Netflix’s ‘Single’s Inferno‘ season 4. He knew it would push him out of his shell and into new bonds, but little did he realize this would not only end up being a once-in-a-lifetime experience for him but also open his eyes to affection as well as love at a new level thanks to the endearing Lee Si-An.

Si-An and Jun-Seo Gravitated Towards One Another Organically

While it’s true that both Si-an and Jun-Seo went to Paradise on the very first day itself, they actually went with different partners as they initially truly had little to no interest in one another. The former had an absolutely incredible time with 33-year-old Kim Jeong-Su despite their 8-year age difference, whereas the latter seemed hooked on Chung You-Jin and her beautiful smile. However, things changed once they returned to Inferno since Jeong-Su as well as You-Jin began showing signs of possibly being interested in others, putting off their respective former dates.

The fact Jang Theo subsequently unabashedly began expressing his sincere inquisitiveness towards Si-An also affected her choices, especially as no one else was being so brashly forward. At this same point, Jun-Seo was naturally pulled towards the perpetually bubbly Kim Min-Seol, resulting in these vibrant individuals being the duo in question’s next Paradise dates. This time around, while the 26-year-old model started developing a deep attraction for Theo, the 28-year-old actor and artist realized Min-Seol was more like a sister to him than a life partner.

That’s when Jun-Seo’s attention shifted toward Si-An, driving him to be honest about his feelings for her and them going on two consecutive Paradise dates to really get to know one another. She realized within these 48 hours that he was truly quite assertive and “macho” and not like the “soft man” she imagined for herself, but she also felt an indescribable sense of comfort as well as peace with him. The fact he listened to her emotional turmoil regarding her interest in three different men without any expectations while also not holding back on his own affection for her is what swayed her.

Si-An and Jun-Seo Are Likely in a Serious Relationship Today

Even though Si-An didn’t appreciate how Jun-Seo was often way too casual with her and referred to her as “hey” rather than using her name, she admittedly always felt giddily different around him. Nevertheless, she still picked Kim Jeong-Su for her final Paradise date to really understand her own emotions, only to realize she had expectations solely from the former because she simply liked him. Therefore, of course, when the time of the final matching rolled around, Si-An and Jun-Seo didn’t hesitate to choose one another, resulting in them leaving the show with her over his shoulder.

Well, we are happy to report that from what we can tell by their public standing, it appears as if they are actually in a happy, healthy, stable relationship as of writing. Si-An and Jun-Seo not only follow one another on social media, but they also seem to keep in constant contact. In fact, the latter recently shared a photo of them together on Instagram. As if that’s not enough, they have reportedly even been spotted together on dates quite a few times over the past few months, in late 2024 and early 2025, indicating a lasting romantic involvement.

Si-An and Jun-Seo Appear Perfectly Content These Days

While freelance model Si-An seemingly prefers not to share much about her personal experiences on her online platforms, they do make it evident that she is leading a blissful life as of writing. After all, she is seeing great success in her career and has recently even embraced her passion for traveling by exploring different areas in Korea as well as in the US (California and Arizona). She also made it clear in early February 2025 that she doesn’t regret any aspect of her time in the aforementioned show, possibly indirectly alluding to her connection with Jun-Seo.

Coming to Jun-Seo’s personal standing, he too is thriving both personally and professionally as of writing, especially considering his bond with his family, his likely ongoing romance with Si-An, his success in the entertainment industry as an actor as well as model, and his recent art exhibitions. In fact, the fitness enthusiast now has his own studio, has collaborated on a project with Samsung Korea, has been a part of Netflix’s ‘Sweet Home’ season 3, as well as landed a credit in the ‘Cranium’ exhibition held in Kumho, Seoul. Honestly, we can’t wait to see what’s in the cards for him next.
