Our Universe K-Drama Cast Secrets: What Park Seo Ham, Roh Jeong Eui & Bae In Hyuk Do After a Long Day on Set

If you’ve already fallen for Our Universe on HBO, you’re not alone. The Korean drama that debuted on February 4 has quietly become one of 2026’s most emotionally resonant watches — and getting to know the real people behind the characters makes it even better.

In a candid conversation, the three leads opened up about their off-screen lives: how they recharge, what they eat when they’re exhausted, and how they feel about raising children. Spoiler: it’s just as warm and relatable as the show itself.

How the Cast Unwinds — Off Camera Confessions

Park Seo Ham, who plays Park Yoon Seong, keeps it cosy after a tough day — good food, a favourite show, and people he loves nearby. When exhausted, he gravitates toward something indulgent like chicken or spicy beef ribs. And his wind-down playlist? A low-lit evening paired with a beer and Do Hyun’s I Guess I Loved You. Very moody, very relatable.

Roh Jeong Eui, who portrays Woo Hyun Jin, finds comfort in the simple act of coming home to family. For food, she goes all-in with shabu-shabu — working through meat, vegetables, noodles and finishing with porridge. Her relaxation playlist leans into piano instrumentals to clear her mind. It’s the kind of self-care ritual we all aspire to.

Bae In Hyuk is a self-proclaimed pizza-and-TV person. Simple, effective, no fuss. He winds down with Jin Ah’s soothing music in the background and relishes the quiet solitude after long shoots.

The Parenthood Question — And Their Honest Answers

Given that Our Universe is built around unexpected caregiving, it was fitting to ask. Jeong Eui has babysat her nephew before. In Hyuk admits he barely sees his young cousin during holidays. Seo Ham skipped babysitting duties entirely — but has vivid memories of playing with his brother, who is eight years younger.

Their advice to hardworking parents was genuinely moving. In Hyuk expressed gratitude for parents navigating challenges with love, Jeong Eui urged new parents to stop being so hard on themselves, and Seo Ham offered pure respect and encouragement for a journey he hasn’t yet taken himself.

Korean dramas have long excelled at turning everyday emotional truths into deeply moving television — and Our Universe is a perfect example of that tradition continuing.
