Shocking reveal: Actor Ryu Si-won is finally showing his day-to-day married life on TV for the first time — with his wife who is 19 years younger — drawing massive attention.

In the latest teaser for TV Chosun's variety show Joseonui Sarangkkun, Ryu appears side by side with his wife. Introducing her, he says, "This is the first time I'm properly revealing her on a show. My wife," before adding, "If I let her go, I knew I'd regret it for the rest of my life. Just having her by my side makes me feel strong." His wife echoed the sentiment: "It's fate. Even if I were born again, I'd still meet him."

The couple first sparked buzz when they were spotted attending comedian Yoon Jung-soo's wedding as guests. A brief clip showing Ryu's wife quickly went viral online, racking up about 2.67 million views. Yoon even remarked in surprise, "She looks like that — and she's a math teacher."

Shrouded in mystery until now, Ryu's wife is a math instructor based in Daechi-dong, and she has been indirectly mentioned on multiple programs. On shows like Gourmet Heo Young-man's Baekban Travels and Dolsing Fourmen, Ryu shared her background, saying things like, "She hustled her way up and became a star instructor in Daechi-dong," and "These days, she earns more than I do," grabbing headlines. Notably, even after receiving a major offer from a top private academy right before their wedding, she chose marriage without hesitation — a story that left a strong impression.

Ryu married for the first time in 2010 and divorced in 2015. He remarried his current wife in 2020, and after IVF treatment, they welcomed a daughter in 2024.
