Stephanie Soo, the popular mukbang and ASMR YouTuber, is married to a man known publicly as Rui Qian, or by his online alias MisterMangoButt. The couple got engaged in 2019, and Stephanie announced their marriage in a YouTube video posted on July 21, 2023.
He’s known for keeping his face hidden in her content — usually behind an oversized panda mask — which has become one of the most talked-about parts of their relationship online.
Who Is Stephanie Soo?
Stephanie Soo was born on November 27, 1995, and is known for her mukbang and ASMR videos, often featuring large quantities of spicy or comfort food. She’s built her channel into one of the biggest names in the eating-show genre, and her second channel — often referred to by her fans as MissMangoButt — is where she shares more of her personal life, including glimpses of her relationship.
That mix of food content and personal storytelling is exactly why so many fans end up searching for details about who she’s dating or married to.
Who Is Stephanie Soo’s Husband? Meet Rui Qian / MisterMangoButt
Her husband’s name is Rui Qian, though he’s far better known by his nickname, MisterMangoButt — a play on Stephanie’s own vlog handle. He’s reportedly kept a low profile, with Stephanie and others regularly obscuring his face in videos and photos using masks, camera angles, or other coverings. He’s been connected to Harry Winston in a sales or advisory capacity, and his Instagram presence has also touched on fashion modeling.
The panda mask is really his signature move. Whenever he shows up in a video or a photo, chances are his face is covered by it, which has turned into a running joke — and a genuine mystery — for Stephanie’s audience over the years.
Fact vs. Rumor – Why You’ll See Different Names Online
If you’ve done any searching on this topic before landing here, you’ve probably noticed something strange: different sites name her husband differently. Some call him “David.” Others say “Albert,” “Brian,” or “Eric Choi.” A few even claim he’s a software engineer living in Seoul, or that Stephanie herself is South Korean-born and based in Korea, which doesn’t match up with the more consistent details out there.
This is a pretty common problem with celebrity gossip content — a lot of these articles are generated in bulk without anyone actually checking the facts, and once one wrong name gets repeated enough times, it spreads across dozens of copycat pages. The name that shows up consistently across more reliable coverage — including entertainment outlets that reported on the actual wedding — is Rui Qian, known online as MisterMangoButt. That’s the name worth trusting here.
The Verified Relationship Timeline
Here’s how their relationship has unfolded, based on what Stephanie and her husband have actually shared publicly.
How They Met and Started Dating
The two are believed to have connected in the early 2010s, and Stephanie has referenced their early relationship in her own videos over the years, though she’s kept most of the specific details private.
The Panda Mask Debut — When Anonymity Began
Early on in Stephanie sharing her relationship with fans, her partner started appearing on camera and in photos wearing an oversized panda mask instead of showing his face. It’s stuck ever since, becoming one of the most recognizable running elements of their relationship content.
The Engagement
The couple got engaged in 2019. In a January 27, 2023 Instagram post, Stephanie reflected on the milestone, writing that after many years together they’d decided to get married and that she’d be sharing the wedding later that year.
Current Status as of 2026
Stephanie announced their marriage in a YouTube video posted July 21, 2023, titled “We got married!” The ceremony took place in a small chapel in Switzerland, and the video included family messages along with footage from the day itself. As far as publicly available information goes, they remain married. If you want the most current confirmation, her own YouTube and Instagram accounts are the best place to check, since that’s where she’s shared every major update about the relationship so far.
Why Does Stephanie Soo’s Husband Hide His Face?
Stephanie has never given one definitive reason for the panda mask, but it fits a pattern that’s pretty common among creators, especially in the mukbang and lifestyle space. Some do it because their partner isn’t a public figure and simply doesn’t want to be recognized. Others keep it up because it’s become a fun, branded part of their content — which seems to be at least part of what’s happening here, since the mask has turned into something fans actively look forward to seeing rather than something that feels like it’s hiding a secret.
It’s worth noting this isn’t unique to Stephanie. A number of streamers and YouTubers in similar niches keep partners off-camera or disguised, usually as a way to protect someone who didn’t sign up for internet fame just by being in a relationship with a creator.
Where to See Them Together (Video & Post References)
If you want to see the relationship for yourself rather than just reading about it, here’s where to look:
- Her main YouTube channel — the “We got married!” video, posted July 21, 2023, documents the wedding ceremony and includes messages from family
- Her second channel (MissMangoButt) — this is where she’s shared more personal, relationship-focused content over the years
- Instagram — her January 2023 post announcing the upcoming wedding is one of the clearest, most direct statements from Stephanie herself about the relationship
- His alias account — MisterMangoButt has his own Instagram presence, where he appears consistently in the panda mask
Checking these directly is the best way to get the full context, rather than relying on secondhand summaries.
