Actor Yoon Si-yoon’s Meticulous Life: The ‘Planning King’ of ‘My Little Old Boy’

Actor Yoon Si-yoon has newly joined the cast of the SBS variety show, My Little Old Boy. In a first for the actor, he revealed his home and private life in an hour-long segment dedicated solely to him, drawing a great deal of attention. The personas he showed on the broadcast include ‘Alarm King,’ ‘Planning King,’ ‘Cleaning King,’ ‘Organization King,’ ‘Car Wash King,’ ‘Self-Control King,’ and ‘Effort King.’ These are traits rarely seen, even individually, in the average person. Among them, his habit of planning a month’s worth of outfits in advance was particularly impressive. Another space appeared within Yoon Si-yoon’s game room: his closet. Inside, clothes were perfectly categorized by type and color. Yoon Si-yoon: “I want my closet to be in great condition, like a clothing store. To do that, you can’t have too many clothes. The clothes shouldn’t overlap (referring to the evenly spaced clothes). There’s a maximum number of hangers that can fit on the rack. If I run out of hangers? Then I get rid of clothes.” Yoon Si-yoon then spreads out his accessory case and clothes in the living room. Yoon Si-yoon: “Let’s set up the plan for June.” His May calendar is already filled with photos of his outfits. He had attached pictures of his daily styles in advance, even for his days off. Production Staff: “Are you interested in fashion?” Yoon Si-yoon: “No. I was even chosen for a ‘worst dressed’ list in the past. As I’m turning 40, I want to try changing my style, and I think I need to challenge myself with clothes that aren’t my usual style, even for daily wear. But since I have no interest in clothes, don’t dress well, and lack confidence, I’ve decided to consult with my stylist to plan a month’s worth of outfits in advance and just wear them according to the plan.” His phone contains the outfits discussed with his stylist. Today is the day he tries on the pre-planned outfits for June. The June 1st outfit is an all-black look he will wear on a date with his mother. After trying it on, he takes a photo for confirmation. Si-yoon chooses the accessories himself. He selects two pearl necklaces. Then, a pearl bracelet to match. The result is a ‘too much’ look, covered in pearls. Next is a black jacket with white pants, and again, two pearl necklaces. Production Staff: “What is your favorite accessory?” Yoon Si-yoon: “Pearls! I think pearls are great. They somehow make me feel healthier. I like a retro vibe, and pearls fit that perfectly. I love pearls so much.” His accessory box is full of pearls. A pearl necklace with a black jumper. A pearl necklace with a white shirt. A pearl necklace with a leather jacket. A pearl necklace with a blue shirt. He is a man who is truly serious about his pearls. After confirming the outfits, he begins writing something down. Yoon Si-yoon: “I can wear the white outfit in Singapore, so I should make this my airport fashion.” He is recording each outfit he just tried on in his calendar. For script readings, I’ll mostly wear suits. I should wear a white t-shirt to the baseball game. For the first rehearsal… When visiting grandma… When meeting mom… Once he finishes coordinating his daily wear, the June outfit plan is complete. Actor Choi Jin-hyuk’s mother: “I think he’s the first celebrity ever to plan a month’s worth of clothes.” He takes something out of a drawer. He places a t-shirt on top of it and folds it perfectly. He manages his t-shirts with the same care as a clothing store, keeping each one neat. He places the beautifully folded shirt back exactly where it was in the closet, ensures the space between the shirts is uniform, and finishes with a fragrance spray. Singer Daniel: “I’m curious. I’d like to try living with that exact routine.”

“The Ultimate Self-Management King – Yoon Si-yoon Appears on SBS’s My Little Old Boy”

Actor Yoon Si-yoon first gained public attention through the 2009 MBC sitcom High Kick Through the Roof. While the show brought him recognition, it wasn’t enough to label him a “star.” His real breakthrough came with KBS2’s Wednesday-Thursday drama Bread, Love and Dreams, where he played the lead role, Kim Tak-goo. The drama hit an astonishing viewership rating of 50%, catapulting him into top star status. These days, with the changing media landscape, even a 10% rating is considered a huge success—so 50% is nearly unimaginable now. Ever since Bread, Love and Dreams, Yoon Si-yoon has been regarded as a true star. Now, Yoon Si-yoon has newly joined the cast of SBS’s My Little Old Boy. Born in 1986, he’s now 40 years old in Korean age—or 456 months. As an unmarried man past the typical marriage age, his appearance on the show feels fitting. While he was a familiar face on KBS’s 2 Days & 1 Night, his appearances on variety shows have since become rare. This marks the first time he’s featured in a program for a full hour, showing not only himself but also his home and private life—hence, the public’s growing interest. On My Little Old Boy, the show revealed Yoon Si-yoon’s daily life, which was quite unusual. Beyond his star quality, the unique way he lives drew attention. His day started and ended with alarms—he divides his day into scheduled time blocks, guided entirely by alarms. Below is a chronological account of his daily routine, from waking to sleeping. Alarm King – Living by the Minute 7:00 AM – Wake UpThe lights in his room automatically turn on, and his alarm goes off. He gets up immediately and makes a protein shake for breakfast. He cleans up right after using each item. As he’s making the shake, another alarm sounds. 7:03 AM – Take Protein and SupplementsRight on time, he drinks the protein shake and takes his vitamins. Then another alarm. 7:07 AM – Vocal Warm-UpsEverything he does is followed by an alarm, prompting a production staff interview. Yoon Si-yoon:“I schedule my alarms the day before. A monthly and weekly plan is a must. If I don’t plan my day, I might waste it doing meaningless things outside. I’m terrified of becoming lazy. I’m actually very lazy by nature, so if I don’t plan things, I won’t get anything done. Really, truly.” Production Team:“Do you get anxious if your schedule isn’t followed?” Yoon Si-yoon:“I feel uneasy. Things fall out of place. I feel most comfortable when I live according to plan—it energizes me.” To avoid becoming lazy, he meticulously follows his alarms. Even during vocal warm-ups, he cleans the used cup immediately. He practices vocal exercises while lying near the window with a view of the Han River. Then another alarm sounds—time to run to the gym. Bodybuilding King – Aiming for 5% Body Fat 7:50 AM – Gym RunningHe begins running as soon as he arrives. Production Team:“You seem to have lost a lot of weight?” Yoon Si-yoon:“I’m preparing for Taxi Driver 3. I want to create a character that looks emaciated and sunken.” Production Team:“What’s your current body fat percentage?” Yoon Si-yoon:“About 6.5% as of last week.” Production Team:“What’s your goal?” Yoon Si-yoon:“5%. They say you need to hit 5% for visible six-pack abs.” MC Seo Jang-hoon compares it to singer Kim Jong-kook’s 9% and Cristiano Ronaldo’s 7%. Despite already losing 10 kg, Yoon continues daily workouts to reach 5%. He runs intensely for 30 minutes without rest. 8:20 AM – Personal Training (PT)During PT, he gives powerful shouts, revealing defined muscles and visible six-pack abs. Breakfast in 20 Minutes 9:00 AM – Back HomeAfter showering, he applies lotion while admiring his muscles in the mirror. Another alarm. 9:40 AM – Breakfast TimeWith a 10 AM schedule, he has only 20 minutes to cook and eat. He quickly prepares two dishes: Everything is done swiftly and neatly. He finishes eating in 8 minutes and immediately washes dishes in 2 minutes. Another alarm. Always Preparing – English & Japanese Lessons 10:00 AM – English Lesson (Phone Conversation)He practices speaking English related to an upcoming drama role. Yoon Si-yoon:“One day, my mom handed me two random English books. I asked, ‘What is this?’ and she said, ‘You’re on TV but your English is terrible.’ I felt ashamed. I had so many great opportunities but missed them because of language. I regretted it so much. I told myself I’ll get another chance, and I have to be ready.” His study room is packed with English books. After an hour, his next lesson begins. 11:00 AM – Japanese Lesson (Phone Conversation)He steadily prepares for future opportunities by learning Japanese. Back to Acting – Character Study & Practice 12:00 PM – Acting PracticeIn his home theater, he watches dramas, eats salad, pauses scenes to take notes and mimic the characters, repeating the process. Even Rest is Regulated 1:00 PM – Game TimeHe enters his game room for the first break of the day. Just 15 minutes in, the monitor shuts off. Yoon Si-yoon:“If I don’t limit game time, it never ends. I preset the monitor to turn off after 15–20 minutes.” Even his rest is planned and limited. Outfit Planner – Planning a Month of Outfits He heads to his closet, where clothes are neatly sorted by color and type. He lays out outfits for June, referencing style photos he discussed with his stylist. Every outfit—casual to TV appearances—is preplanned. Production Team:“Are you into fashion?” Yoon Si-yoon:“No, I was once picked as a worst dresser. I just want to try different looks in my 40s. I’m not confident, so I plan a whole month of outfits in advance with my stylist.” His favorite accessory? Pearls. Everything—black jumper, white shirt, leather jacket—is matched with pearl necklaces. After trying on outfits, he documents each look on a calendar. His goal is clarity and confidence in his style.
