Korean actor Yoon Shi-yoon has officially joined the SBS variety show My Little Old Boy. Born in 1986, he is now 40 years old (Korean age), making him the perfect fit for a program that often highlights unmarried celebrities and their unique lifestyles. While fans once saw him regularly on 2 Days & 1 Night, this is the first time Yoon Shi-yoon has appeared in a program where his home and personal life are showcased for over an hour. Naturally, curiosity grew: How does a top Korean actor really live behind closed doors? Rise to Stardom: From High Kick to Baker King Kim Tak Goo Yoon Shi-yoon first gained recognition in 2009 through the MBC sitcom High Kick Through the Roof. However, it was the 2010 KBS drama Baker King Kim Tak Goo that skyrocketed him to nationwide fame. Playing the lead role “Kim Tak Goo,” Yoon became a household name after the drama reached a record-breaking 50% viewer rating—a number considered impossible in today’s media landscape, where even 10% is seen as a massive hit. Since then, Yoon Shi-yoon has been regarded as a true K-drama star. Extreme Self-Discipline: The Actor’s Strict Lifestyle On My Little Old Boy, Yoon Shi-yoon impressed audiences with his military-like self-discipline. Every part of his day is scheduled with alarms—from waking up to eating meals, exercising, studying languages, and even resting. Yoon explained: A Perfectly Organized Home: Cleanliness is Healing Yoon Shi-yoon’s home is nothing like an ordinary living room. Instead of a sofa and TV, his living space resembles a library and workspace. Everything is arranged in perfect order—bookshelves, kitchen items, refrigerator contents, clothing, shoes, and even bathroom supplies. Yoon explained his obsession with order: “When I come home, I want my house to welcome me perfectly. Cleanliness gives me healing and strength.” He even avoids placing a sofa in his home, explaining: “The sofa is the laziest spot in the house. I eliminated it so I wouldn’t have a place to waste time.” Fashion and Accessories: Planning a Month Ahead Although not naturally fashion-conscious, Yoon Shi-yoon now plans his outfits a month in advance with the help of a stylist. His calendar includes daily outfits for work, events, and family visits, complete with photos. Car Care Enthusiast: “Car Wash is My Healing Time” Another highlight was Yoon Shi-yoon’s passion for car washing. Wearing a jumpsuit and using dozens of cleaning tools, he spends two hours washing only the exterior of his car. From high-pressure rinsing, snow foam spraying, tire scrubbing, to waxing, his detailed car wash routine stunned both the show’s hosts and viewers. He compared the process to meditation: “Cleaning excites me. Watching dirt disappear makes me feel healed.” Despite owning a 12-year-old car, his meticulous care makes it look brand new. Ending the Day: Whiskey Aroma Without Drinking After his long, structured day, Yoon Shi-yoon ends the evening with a unique ritual. He prepares a smoky whiskey pairing but doesn’t drink it—instead, he only smells it. Inspired by Robert Downey Jr., Yoon avoids alcohol for body fat control: “Alcohol affects body fat more than food. I’ve been abstaining for six months, and my body fat finally dropped below 10%.” Before bed, he locks his phone in a digital detox box to avoid late-night screen time, ensuring quality sleep. His day ends at 10:00 p.m. with lights out and an eye mask. Yoon Shi-yoon’s Philosophy: Fighting Laziness with Discipline Yoon Shi-yoon confessed multiple times: “I am terrified of becoming lazy. I’ve been blessed with more than I deserve, so I live with strict discipline to avoid wasting it.” His relentless schedule, meticulous cleaning, strict diet, and organized lifestyle show a man determined to maintain balance between success and humility. Fans now see him not just as an actor but as a symbol of discipline and self-management.
