The world of K-drama is basically a giant soap opera that sometimes spills over into real life. When Son Ye-jin and Hyun Bin—the legendary duo from Crash Landing on You—actually got married in 2022, the internet collective lost its mind. But the real obsession started later. People have been scouring the web for any scrap of info about Son Ye-jin son, the little boy who arrived in November 2022. It’s a weird mix of genuine love for the couple and an almost feverish curiosity that the parents are clearly trying to manage.
They’re private. Like, really private.
You won't find high-res paparazzi shots of his face on her Instagram. Instead, you get a photo of a tiny, chubby hand or a pair of baby socks. It’s a deliberate choice. In an era where "sharenting" is the norm for influencers, Son Ye-jin and Hyun Bin are old-school. They want their kid to have a life that isn't lived through a smartphone lens before he can even talk.
The Birth of the "BinJin" Prince
Let’s get the facts straight because there’s a lot of noise out there. Son Ye-jin gave birth on November 27, 2022. It was a bit of a surprise because the baby came slightly earlier than the December due date most people were expecting. Hyun Bin was actually filming the movie Harbin in Mongolia at the time, leading to a flurry of rumors that he missed the birth. Her agency, MS Team Entertainment, had to step in and clarify that, no, he was actually there. He made it back. He saw his son enter the world.
Honestly, it’s kind of refreshing. In the West, we’re used to People Magazine covers. In Seoul, the "BinJin" son is treated like royalty, but the castle walls are high. Fans have nicknamed him "Little Alkong," a play on a Korean term for being lovey-dovey.
Growing up as the son of two of South Korea’s biggest Hallyu stars isn't just about fancy clothes. It’s about a massive weight of expectation. Son Ye-jin has spoken briefly about the experience of motherhood, calling it a time of "great realization." She posted on Instagram that she finally felt like she was "becoming an adult." That’s a heavy sentiment from someone who has been in the spotlight for over two decades. It suggests that for her, the Son Ye-jin son isn't just a "celebrity baby"—he’s a life-altering shift in her identity.

Who Does He Look Like?
This is the question that keeps the forums at Soompi and Reddit buzzing late at night. Does he have Hyun Bin’s dimples? Does he have his mother’s "eye smile"?
During an appearance on the golf YouTube channel Imjin Han Golf, Son Ye-jin finally gave the fans a tiny bit of "tea." She mentioned that people say the baby looks like a perfect mix of both parents. Specifically, she noted that he has her eyes and his father’s lower face. But then she added a classic mom comment: "Babies' faces change all the time."
Think about the genetics here for a second. You have the man often cited as the "most handsome actor in Korea" and the woman known as the "Nation’s First Love." The kid basically hit the genetic Powerball. But the parents are keeping that face under wraps. When Son Ye-jin does post, it’s often a comparison shot—her own childhood photo next to a photo of her son’s hand or foot. The resemblance between her as a toddler and her son is actually pretty striking.
The Reality of Parenting in the Spotlight
It’s not all glamour. Son Ye-jin has been candid about how hard the work is. She hasn't jumped back into a 16-episode drama series immediately. Why? Because she’s doing the "mom thing" full-time.
She’s been seen at baby fairs. Real fans have spotted her picking out strollers and clothes just like anyone else. This groundedness is why her fanbase is so protective. If a "leaked" photo of the Son Ye-jin son appears on a shady blog, the "BinJin" fandom usually reports it into oblivion. They respect the boundary because they’ve followed her career since The Classic and A Moment to Remember. They feel like they’ve grown up with her.

There’s a cultural layer here, too. In South Korea, privacy regarding the children of celebrities has become a much hotter topic lately. Actors like Jo Jung-suk and Gummy, or Chen from EXO, have also been very careful. It’s a reaction to the intense "sasaeng" (stalker) culture that has plagued the industry for years. By keeping her son out of the public eye, Son is effectively shielding him from a life where he’s scrutinized before he even starts preschool.
Balancing Career and "Alkong"
Many wondered if she’d retire. Thankfully, that doesn't seem to be the case. She’s been doing brand shoots for Valentino and other high-end labels. But she’s picky now. Every day she spends on set is a day away from her boy.
Hyun Bin, for his part, has been the "doting dad" trope personified in interviews. While promoting The Point Men and Confidential Assignment 2, he couldn't help but glow when the baby was mentioned. He’s described his son as a "blessing" and admitted that he now feels a much heavier sense of responsibility as the head of the family. It’s a far cry from his cool, detached characters.
Misconceptions and Internet Rumors
Because there is so little official info, the vacuum gets filled with nonsense.
- Rumor 1: They have a dozen nannies. While they certainly have help, Son has been very vocal about wanting to be hands-on. Her social media shows her cooking healthy meals and being deeply involved in the day-to-day.
- Rumor 2: He’s going to be a child actor. There is zero evidence for this. In fact, given how much they value privacy, it’s more likely they’ll push him toward a "normal" education.
- Rumor 3: The marriage is struggling. This one pops up every six months on YouTube clickbait channels. It’s usually debunked within hours by a photo of the two of them on a golf date or a sweet anniversary post.
The Son Ye-jin son is growing up in a home that seems, by all accounts, incredibly stable. In the volatile world of entertainment marriages, that’s the real story.

What’s Next for the Family?
As we move through 2026, the "Little Prince" is now a toddler. This is the age of running around, getting into everything, and starting to develop a real personality. Son Ye-jin has started to slowly increase her public appearances, attending fashion shows and events, but the focus remains on her home life.
Fans should expect more of the same: occasional, cryptic, and incredibly cute photos of a toddler's back or a shadow on the wall. And honestly? That’s for the best. The mystery is part of the charm, but the protection of his childhood is what actually matters.
If you’re a fan looking to support the family, the best thing you can do is avoid clicking on "leaked" images or supporting accounts that invade their privacy. The "BinJin" story is a rare "happily ever after" in the celebrity world. Let them keep their private moments private.
Next Steps for Fans:
- Follow Official Channels Only: Stick to Son Ye-jin’s verified Instagram (@yejinhand) for any actual updates. Anything else is likely speculation.
- Respect the Boundary: If you happen to be in Seoul and spot them (they often frequent the Gangnam and Hannam-dong areas), keep your distance. Don't take photos of the child.
- Support Her Work: The best way to show love is to watch her upcoming projects. This allows her to maintain her career while feeling secure that her fans value her talent over her private family life.
- Ignore the Clickbait: Avoid YouTube channels that use AI-generated voices to spread "exclusive" news about the baby’s health or school. These are almost always fake.
