He Showed Up at Her Parents Door Two Days In — And Married Her

Musical actress Kim So-hyun revealed on YouTube that her younger husband, Son Joon-ho, showed up at her parents' house just two days after they decided to start dating — and he had already made up his mind that he was going to marry her. What followed is one of the most delightfully determined love stories in Korean entertainment.

Kim So-hyun and Son Joon-ho, who have been one of the most celebrated couples in Korean musical theater for 15 years, recently appeared as guests on the online channel Working Mom Lee Hyun-i, where they shared the full story of how their relationship began — and why it moved at such an unusually fast pace.

The Two-Day Move That Changed Everything

Son Joon-ho, eight years younger than his wife, did not waste time once the two had decided to become a couple. Within two days of making things official, he showed up at Kim So-hyun's family home — not with flowers, but with a clear intention. He wanted her parents to know he was serious.

"Right after we decided to start dating, he came straight to my parents' house," Kim So-hyun recalled. "And my mother ended up talking with him for three hours." It was the kind of audacious, all-in move that tends to either impress a family immediately or put them on guard. In this case, it clearly did the former.

Son Joon-ho, for his part, was characteristically self-deprecating about the timeline. He described how the relationship progressed: after ten months of dating, they were married — and according to him, it was entirely because his partner made clear that she was ready. "She kept asking when we were getting married," he said with a laugh. "So I just said, 'You want to? Okay, let's do it.'" Kim So-hyun cheerfully confirmed that she had indeed pushed for it, adding that his showing up at her parents' place two days in was proof enough that he had already decided.

The Kiss That Started It All

The couple also revealed the moment their professional relationship became something more personal. Kim So-hyun did not exactly hold back: she made the first move. Son Joon-ho recalled the specific day she kissed him, noting that it was the same day he had agreed to go on a date with her — which, in his retelling, made clear who was driving the relationship forward.

"I was the one who kissed him first," Kim So-hyun admitted without hesitation, drawing laughter from the audience. It was a detail that delighted viewers, given the couple's image as a polished, graceful pair known for their work in prestige musical productions.

The two first met while performing together in The Phantom of the Opera, where they played opposite each other on stage. Son Joon-ho, notably, did not call her "noona" — the Korean term of respect for an older woman — from the very beginning, which Kim So-hyun described as intentional on his part. He used her character's name from the musical instead, a subtle but deliberate choice that signaled from the start that he was not going to treat her as simply an older colleague.

Winning Over a Seoul National University Father-in-Law

No part of Son Joon-ho's pursuit was more entertaining to audiences than his attempt to bond with Kim So-hyun's father — a nephrology professor at Seoul National University, one of Korea's most prestigious academic institutions. Son Joon-ho attended Yonsei University, SNU's chief rival. Walking into that meeting required some preparation.

His strategy was thorough, if imperfect. He watched medical dramas to learn medical terminology, hoping to find common ground with his potential father-in-law. The plan backfired slightly: most medical dramas focus on surgery, so his vocabulary was heavily surgical — while his future father-in-law specializes in internal medicine. The resulting conversation was cordial but slightly mismatched in terminology, which Kim So-hyun recounted with visible amusement.

Despite the vocabulary mismatch, the effort itself apparently made an impression. Over time, her father warmed to his son-in-law considerably. The family also became widely recognized in Korean internet culture for the phrase "Just go eat in Sinchon" — a reference to Yonsei University's neighborhood — allegedly from Kim So-hyun's father to his Yonsei-educated son-in-law, which took on a life of its own online as a gentle teasing expression.

Fifteen Years and Still Going

Kim So-hyun and Son Joon-ho married in 2011, the same year they had been performing together in musical theater. Their son, Ju-an, was born in 2012. Now in their fifteenth year of marriage, they remain one of the most visible and celebrated couples in Korean musical theater — a world that has produced a number of high-profile artistic partnerships turned marriages.

Both continue to perform actively. Kim So-hyun has built one of the longest-running careers in Korean musical theater, known for roles in prestige productions across multiple decades. Son Joon-ho has similarly established himself as one of the genre's leading male performers, with credits in major productions and a reputation for his vocal range and stage presence.

Their appearance on Working Mom Lee Hyun-i was notable not just for the personal revelations but for how naturally they told the story together — filling in each other's details, gently correcting each other's memory of events, and laughing at the absurdity of how fast everything moved. Fifteen years in, the story of a man who showed up at a woman's parents' door two days into dating clearly still amuses them both.

Why the Story Resonates

Audiences responded warmly to the couple's openness. Comments on the video highlighted how refreshing it was to see a long-married entertainment couple speak candidly about the practical, sometimes chaotic mechanics of falling in love — rather than presenting a polished, sanitized version of romance.

What the story captures, ultimately, is the portrait of two people who recognized something clearly and moved without hesitation. Son Joon-ho arrived at her parents' home in two days because he had already decided. Kim So-hyun pushed for marriage because she had already decided too. Fifteen years and a son later, the speed turns out to have been entirely justified.
