Trends in Korea move fast. Look away for a month and there’s a whole new thing everyone already knows about. So here are five that caught our eye this week — read them together and you’ll get a pretty good feel for the mood here right now.

1. AI-generated “romance fantasy” dramas

Short dramas made entirely with AI are popping up all over YouTube and Instagram. Most episodes run just 5 to 10 minutes.

The genre winning hardest is romance fantasy — and the reason is genuinely interesting. These stories are usually set in European-style palaces, with impossibly beautiful characters and elaborate interiors. All things that are expensive or impossible to shoot for real, and easy to generate with AI.

The YouTube channel Wingcardia collaborated with Naver Series to create a live-action-style version of the web novel Rosetta. It pulled 220,000 views in five days.

The response isn’t purely starry-eyed, though. Plenty of viewers point out that the same AI tools produce wildly different results depending on the writing and direction — the craft still matters. Others worry about actors’ faces and voices being used as training data. The familiar questions that follow any new technology.

2. “Multi-age”: when age stops predicting taste

This one hits home. People in their 20s and 30s are enjoying things marketed to teenagers — squishy toys, Roblox — while new hires straight out of university are already researching retirement pensions.

The old formula where your age dictated what you bought is breaking down. People now spend their time and money based on what they’re actually into. The trend media outlet Careet calls this “multi-age.”

3. The comment meme: “[X] info, please”

You’ve probably seen Instagram posts saying “comment ‘makeup info’ and I’ll DM you the product links.” That format spawned a meme.

Now people drop “OO 정보” (info on [X]) in the comments of any post, regardless of context. For example:

“My little sibling came back from a trip and bought me my favorite figure 🥹” → “#siblinginfo”

They’re not actually asking who the sibling is. It means “I want a sibling like that.” It ties into a broader shift where people happily post about being close with their families instead of hiding it — a surprisingly wholesome meme.

4. Baseball mascots are getting idol-level attention

The Kiwoom Heroes’ newer mascot, Donggeuri, is having a moment. She’s canonically the younger sister of the team’s existing mascot, Turkdori, and clips of her teasing fans and playing to the crowd have been spreading across social media with everyone yelling about how cute she is.

She’s not the only one. The SSG Landers’ Betty and the KIA Tigers’ Harang are getting fresh attention too. As KBO baseball’s popularity keeps climbing, the mascots have become content in their own right.

5. McDonald’s fry holder — sold out in under 5 days

McDonald’s Korea released a french fry holder available only at McDrive (drive-thru) locations. It sold out in less than five days.

What’s interesting is why it worked. It’s not a collectible you display on a shelf — it actually makes using the brand easier. Anyone who has tried to eat fries in a moving car understands immediately.

Looking at all five together, there’s a pattern: the things that take off in Korea right now are the ones you can do yourself, photograph, and show off. Curious what next week brings.
