Single’s Inferno 4 stars Yuk Jun Seo, Lee Si An, Kim Jung Soo, and Kim Min Seol reunited for a fiery conversation, and Lee Si An’s unexpected comment stole the show.
On the March 29 episode of MBC’s The Manager (Ep. 340), Yuk Jun Seo made his first appearance in four years, alongside broadcaster Lee Young Ja’s daily life segment.
Known as the "iron man" of Single’s Inferno 4, Yuk Jun Seo gave fans a glimpse of his new art studio, where he worked on large-scale paintings using a lift, impressing everyone with his dedication.
To create his latest piece, he collected pig bones from his father’s woodworking shop and worked with his manager, music director Lim Young Jin, and a photographer friend to prepare for an exhibition. The team’s synergy resulted in a stunning "pig bone vase" artwork, leaving viewers in awe.

After focusing on art, Yuk Jun Seo met up with Single’s Inferno 4 castmates Lee Si An, Kim Jung Soo, and Kim Min Seol. Fans were especially excited to see the reunion of the beloved “Yuk-Si An” couple.
As they shared behind-the-scenes stories, things heated up when Lee Si An made a shocking confession about the infamous sleeping scene, saying, "I wanted to sleep next to him." Her unexpected comment turned the studio upside down, making the discussion even more intense.
Of course, the big question came up—are Yuk Jun Seo and Lee Si An dating in real life? When Song Eun Yi asked, "Are you two a real couple?" Yuk Jun Seo responded, "We meet and stay in touch as just oppa and dongsaeng (older brother-younger sister dynamic)."
When Yoo Byung Jae asked when they last spoke, he casually answered, "We always end up talking in the evening," making fans of the "Yuk-Si An" couple cheer even louder.
