The Soldier and the Siren: Yuk Jun Seo & Lee Sian’s Epic Love Story
Single’s Inferno Season 4’s most compelling romance reached its crescendo when Lee Sian faced her moment of truth between three eager suitors. Despite a final Paradise date with Kim Jeongsu that had fans speculating, it was the magnetic pull between Sian and former UDT soldier Yuk Jun Seo (nicknamed “Beast” and “Tarzan” by viewers) that proved impossible to resist.
Their chemistry had been electric throughout the season, with subtle touches and intimate moments speaking volumes. The turning point came during their heart-to-heart conversation, where Sian finally confessed her romantic feelings, causing Yuk Jun Seo’s usually stoic demeanor to melt into genuine emotion.
In perhaps the finale’s most touching moment, Yuk Jun Seo, the Sweet Home actor, delivered a raw and vulnerable speech: “From the very beginning to the very end, nothing went according to what my expectations had been. Through this whole process, I was able to discover new sides of me and I have to thank you for that.” The celebration that followed – with Jun Seo sweeping Sian off her feet while she laughed joyously – became an instant classic moment in the show’s history.
