Yoon Si-yoon, Even Seo Jang-hoon Was Amazed: First Look at His Precise Daily Life on 'My Little Old Boy'
My Little Old BoyActor Yoon Si-yoon, known as the 'ultimate king of organized living,' had his daily life revealed for the first time on 'My Little Old Boy'.

The episode of SBS's 'My Little Old Boy' aired on the 1st, according to Nielsen Korea, ranked first in its time slot with a 2.7% viewership rating among the 20-49 demographic and topped the weekly variety show ratings in the metropolitan area with 11.5%.

The studio welcomed singer Kang Daniel as a special MC, receiving enthusiastic responses. Known for his resemblance to a Samoyed, Kang Daniel shyly admitted, "It seems like women in their 20s and 30s, who know a lot, really like me." MC Seo Jang-hoon joked, "I guess I'm kind of like a guard dog. There are a lot of dogs named 'Jang-hoon' across the country," eliciting laughter.

Kang Daniel, a movie buff, boasted about his collection of lightsabers from various movies. Shin Dong-yup suggested, "I have some nice whiskey in my car; let's trade," making an on-the-spot offer.

Actor Yoon Si-yoon appeared as the 'NEW My Little Old Boy', revealing his home and daily life on broadcast for the first time. The sight of his refrigerator and kitchen cabinets meticulously organized, even down to the apps on his smartphone, drew gasps of amazement. Yoon Si-yoon confessed in a pre-interview, "No matter how busy or tough it gets, I want my home to welcome me perfectly when I open the door. That's why I never let it get messy," to which Seo Jang-hoon exclaimed, "Even I'm not that meticulous," in admiration.

Upon waking, Yoon Si-yoon took protein and supplements three minutes after his alarm, followed by vocal exercises four minutes later. However, the sight of him hurriedly eating before the next alarm had the 'Mom Avengers' laughing, saying, "Does he really need to go to such lengths? We're all in a rush too."

Yoon Si-yoon shared, "I'm currently losing weight to give a haggard look for my character in 'Taxi Driver3'. My goal is to reach 5% body fat." The reveal of his defined abs had MC Shin Dong-yup enviously commenting, "I'd love to have that body for just one day." Yoon Si-yoon, who is also taking English and Japanese lessons, said, "I was embarrassed by a missed opportunity because I wasn't prepared. That's why I started studying," earning admiration from Choi Jin-hyuk's mom, who confessed, "Honestly, I'm envious of that aspect."

Yoon Si-yoon even consults with his stylist to plan a month's worth of outfits in advance. "I was once voted as the worst dresser, so that's why," he explained, earning understanding nods. However, everyone struggled to hold back laughter at his choice to accessorize every look with a pearl necklace, calling it "an unconventional choice."

Meanwhile, Yoon Si-yoon's mother turned the studio upside down with her bombshell comment during a phone call with her son, saying, "The subway restrooms are more comfortable than the one at your house."

Jung Seok-yong, who previously shocked his close friend Lim Won-hee by revealing his romantic relationship, visited a wedding venue this time. "My girlfriend calls me 'Yeong-ae' because she says my skin is as flawless as Lee Young-ae's," he shared, causing Lim Won-hee to barely contain his laughter. Jung Seok-yong's girlfriend surprised the 'Mom Avengers' with her cutesy voice over the phone, saying, "I saved his name in my phone with the initials 'J.S.Y.' It just feels like him."

Moreover, Jung Seok-yong walking down the aisle with a veil on, reenacting a bride's entrance with close friend Lim Won-hee, sent the studio into fits of laughter. Lim Won-hee lamented, "After our 'Senior Care Project', Sang-min left, you're leaving, and now I'm the only one left," unable to hide his gloom.

Shockingly, the broadcast ended with Lim Won-hee, who had been struggling with loneliness, going on a blind date, turning the studio upside down. 'My Little Old Boy' airs every Sunday night at 9 PM.
