Yuk Jun-seo Breaks Silence on Real-Life Romance With Single’s Inferno 4’s Lee Si-an

"Magnetic man" Yuk Jun-seo is finally breaking his silence on whether he and Single’s Inferno 4 co-star Lee Si-an are a real-life couple.

Episode 340 of MBC’s The Manager, also known as Point of Omniscient Interfering View, airing March 29, will spotlight the daily life of Yuk Jun-seo — the UDT-turned-artist whose irresistible charm captivated viewers on Single’s Inferno Season 4.

In the episode, Yuk reveals his new art studio located in a massive commercial complex. With its impressively high ceilings, the space allows him to work on large-scale pieces using heavy machinery like cranes. His industrial-level setup stuns the studio panel, and his laser focus on his craft promises to keep viewers glued to the screen.

Yuk also takes a moment to directly address the viral "40cm mid-face length" debate that sparked online. Laughing off the rumors, he explains that his face mask couldn’t cover his nose properly, which led him to try facial massages to "shorten" his mid-face — a confession that brings plenty of laughs.

Adding to the intrigue, Yuk discusses the question everyone’s been asking: are he and Lee Si-an actually dating in real life? While visiting his father’s furniture workshop, he’s met with the blunt question, “So, do you have a girlfriend or not?” With fans eagerly awaiting the answer, all eyes are on what Yuk has to say.

These days, Yuk is busy preparing for an art exhibition alongside his close friends — a music director and photographer. In the episode, he creates a deeply personal piece using pig bones and flowers, while his friends tackle music production and photography, showcasing their perfect teamwork. A special guest artist is also expected to join the collaboration, raising anticipation for the exhibition even further.
