If you think Seoul is already hot, brace yourself. Weather experts are warning that temperatures in parts of South Korea could approach 40°C (104°F) as an intense heat wave continues. While Seoul rarely reaches that level, a combination of strong sunshine, hot air moving north, and warm overnight temperatures could push the city close to a historic record. Authorities are urging people to stay hydrated, avoid outdoor activities during the hottest part of the day, and check on elderly neighbors and family members.
South Korea’s Han River (한강, Hangang) is much more than a river—it is one of Seoul’s most recognizable landmarks. But in March 2026, it unexpectedly became the center of an online controversy involving a popular finance app and Korean internet culture.
Korean Internet meme 
What happened?
Korean fintech company Toss introduced a small feature that displayed the current water temperature of the Han River. The feature was originally intended for people enjoying water sports, fishing, and other outdoor activities. However, many users immediately associated it with a well-known piece of Korean stock market slang.
Among Korean investors, asking “What’s the Han River water temperature today?” (한강 물 온도 몇 도야?) is a dark joke. It refers to someone who lost so much money investing that they are joking about jumping into the Han River. Because the phrase is associated with financial losses and suicide, many people felt it was inappropriate for an investment app to display Han River water temperatures.
After criticism spread across social media, Toss quickly removed the feature and stated that it had not intended to reference the meme. The company promised to review its approval process for future mini-apps.
Understanding the Image
The image above is a humorous Korean meme titled:
주식 별 한강다리 집합장소
“Han River Bridge Meeting Places by Stock”
The joke imagines that investors who lose money in different semiconductor stocks would “gather” at different Han River bridges. It is an example of the same dark humor that caused the Toss controversy.
The companies are almost entirely memory-chip and semiconductor businesses, reflecting how popular semiconductor investing is among Korean retail investors.
The small text at the bottom (of the first image above) humorously says:
“Please leave in an orderly manner like citizens of an advanced culture. Investment decisions are your own responsibility.”
In other words, it’s a disclaimer reminding readers that investing carries risk.
Why this matters
For foreigners, this may seem like a harmless joke. In Korea, however, suicide is a serious public health issue, and the expression “checking the Han River temperature” has become widely recognized as a reference to despair after financial losses. That social context explains why many people believed a financial services company should avoid using the phrase—even unintentionally.

물 온도 mul ondo, water temperature
다리 dari, bridge
The joke has become relevant again because of South Korea’s dramatic stock market correction in 2026. In just 40 days, the Korean stock market lost an estimated ₩2.5 quadrillion (about US$2 trillion) in market value, while the KOSPI index fell roughly 44% from its late-June peak. The decline was fueled by a rapid unwind of AI-related investments, especially in semiconductor companies such as Samsung Electronics and SK hynix, after investors realized expectations had become too optimistic.
During the selloff, the KOSPI suffered back-to-back daily drops of 10.8% and 6%, one of the sharpest corrections in its history. Despite the crash, the market remained more than 40% higher for the year because of its extraordinary rally earlier in 2026, leading some analysts to believe the worst of the panic selling may be over while others warn that volatility could continue.
In Korea, many young people buy stocks because traditional wealth-building feels harder than ever. Apartments in Seoul are expensive, salaries feel slow, and saving alone can seem boring compared with AI stocks, U.S. ETFs, and chip companies like Samsung Electronics and SK Hynix.
South Korea’s stock market has been on an incredible ride in 2026, powered largely by AI excitement. The country’s main stock index, the KOSPI, surged as investors poured money into semiconductor giants like Samsung Electronics and SK Hynix.
In Korea, girls night isn’t just dinner and drinks — it’s become its own cultural moment blending friendship, food, dancing, and late-night café hops. While Seoul’s nightlife districts like Hongdae and Itaewon buzz with bars and clubs, many young women now start evenings with pre-night meetups (similar to a pregame) at cozy cafés or casual pocha (outdoor food stalls) before hitting dance floors or themed lounges.
In South Korea, bus driving — once seen as a tough, low-status job — is now attracting young workers as well as generating wider social discussion. Recent data shows the number of people in their 20s and 30s getting bus driver licenses jumped sharply (about 43% in three years) due to relatively good pay, job security, and stable hours in the semipublic bus system.
Among Korean teens and twenty-somethings, a quiet but powerful trend is growing: the love for harmless content and ordinary happiness. Instead of loud, shocking, or competitive posts, young people are gravitating toward gentle videos of puppies, simple drawings, small desserts, cozy rooms, miniatures, reading, and slow daily routines. Another popular idea is enjoying “a very ordinary day” — finding joy in coffee, walking home, or watching the sunset.
