Korean Culture After KPop Demon Hunters: Ten Small Customs

A lucky pencil goes into the exam bag, and a registry link goes out with the wedding invitation. Most North American habits around luck and gifts are that quiet and that practical, which makes the Korean versions easy to hold up beside them.

Korea's versions lean on wordplay and calendar quirks, with a lot of cash and candy changing hands. Ten of them already have their own Franvia stories, and this page works as the map: where each one starts, what sits inside it, and which ones have a date coming up soon.

This page is ordered by whatever you would be holding when each custom comes up. A film opens the door, gifts and meals come next, and after them the things people say to each other and the small objects that keep a body warm or safe.

Flat lay of Korean everyday custom objects: chocolate sticks, taffy, a white envelope, a hot pack and seaweed soup
Ten Korean customs, and most of them fit on one table.


A Film Is the Front Door

For many North American viewers, KPop Demon Hunters was a first long look at Korean folk imagery, and a good deal of what looks like fresh invention in it is older than the movie. Halloween monsters in North America are built to frighten, so the Korean originals come as a surprise: they tend to be funny and oddly likable.

Take the tiger and magpie. They come from hojakdo, a kind of minhwa (folk painting) where the tiger is drawn as a bumbling creature and the magpie as the clever commoner who outwits him, which the Korea Times reads as a joke at the aristocracy's expense. The film's demonic Saja Boys borrow from jeoseung saja, Korea's grim reapers, whose black hanbok and gat (a scholar's hat) were popularized by television in the 1970s and 80s, the same report says.

Even the concert stage has an ancestor. According to the Korea Times, the Huntrix backdrop evokes irworobongdo, the royal folding screen that stood behind the throne in Joseon palaces. KPop Demon Hunters Folklore: What the Film Borrowed and Changed starts from those old images and works toward the film, so you meet the original first.

Gifts That Come With a Wink

Korean gifts tend to be small, cheap to give and attached to a pun, a number or a shared script. Three of them show the range: a white envelope at a wedding, a box of chocolate sticks on November 11, and a sticky candy before the biggest exam of the year.

Start with the envelope. Korea has little registry habit, the Korea Herald notes, so a wedding gift is usually cash handed over at a reception table, along with a signature in the guest book and a meal ticket in return.

Amounts vary with closeness. Guests who attend gave an average of 86,300 won in a November 2023 Gayeon survey, against 60,400 won from those who stayed home. The most common amount in Korean surveys is 100,000 won, and a May 2026 survey of 1,500 adults by SM C&C's Tillion Pro put the average at 97,900 won, with 65.3 percent naming 100,000 won as the usual figure. Korean Wedding Gift Money: How Much and How to Give treats those numbers as ranges and spends its time on the moment of hesitation at the desk.

Pepero Day is the lighter cousin. Four sticks standing in a row look like 11/11, so the date explains itself. Pepero launched in 1983, seventeen years after Pocky appeared in Japan, and its maker Lotte began using the name Pepero Day in 1997. In a North American classroom Valentine swap everybody gets a card, while on Pepero Day the giver picks the recipient, and Korean media reported that convenience store sales from November 1 to 11 in 2025 rose by more than 30 percent at both GS25 and CU. Pepero Day in Korea: What People Really Give on Nov 11 follows the boxes through schools, offices and the late-night store counter.

Exam gifts run on a single verb. Butda (붙다) means both to stick and to pass a test, so yeot, a sticky taffy, and chapssal-tteok, a chewy rice cake, become wishes you can eat. A passage in the Annals of the Joseon Dynasty already scolds an exam supervisor for failing to control yeot sellers at the test site, according to the Korea Herald. Korean Exam Day Gifts: Why Yeot and Chapssal-tteok covers the wordplay, the exam morning and the day aircraft are barred from landing during the English listening section, which this year falls on November 19.

Nobody believes a candy changes a score, and most people give it for the reason North Americans knock on wood. The gesture costs little and carries the wish.

Meals Built Around a Bowl

An ordinary Korean meal starts from rice and something hot, and the pattern shows up on school trays and holiday tables alike. September 2026 on one Gyeonggi Province elementary school's published menu had twenty lunches, nineteen of them with a soup or stew and none listing plain white rice.

The menu is full of small surprises. A cheese hot dog arrives with kimchi fried rice, a clear bean sprout soup, roasted seaweed and pickles, so the Western dish is one item among six, and milk appears only once all month. Every student eats for free, a system that reached all school levels nationwide by 2021 according to Korea Herald reporting, and the whole program traces back to donated milk powder in 1953. Korean School Lunch: A Real Month of Menus reads that month week by week.

Chuseok, the harvest holiday, fell on Friday, September 25 this year, about a month before Canadian Thanksgiving on October 12 and two months ahead of the American one on November 26. Both are family feasts, and the difference shows up in the afternoon: Chuseok has a job in it, shaping songpyeon by hand, and the American holiday tends to have football on television. Chuseok vs Thanksgiving: Two Fall Feasts, Two Tables starts in that afternoon, after the plates are cleared.

Letters and Two-Word Texts

Some Korean customs live entirely in conversation, and two of the liveliest are a four-letter personality code and a text message about snow. One gets asked for early on a blind date, and the other gets sent the moment flakes appear.

MBTI is the first. A matchmaking company called Gayeon surveyed 500 unmarried adults aged 25 to 39 in November 2022, and 90 percent said they had taken the test. The same story has limits, since a May 2024 survey by the dating app Weppy found only 9.3 percent of 400 women counting MBTI among the profile details they consider important. Taken together, the two surveys suggest the letters work as a conversation opener and rarely as a filter.

Offices and group chats have their own use for them, a tease along the lines of "Are you a T?" aimed at anyone who answers a feeling with a fact. Hiring is where experts push back hardest, and MBTI in Korea: How It Shows Up on Dates and Resumes lays out their objections.

First snow, cheonnun (첫눈), runs on the opposite clock. For Seoul, the weather service announces it only when an observer at the station in Jongno District sees flakes falling, and the 1991 to 2020 average lands around November 20, though in 2025 it came on December 4. A North American first snow sends people hunting for the ice scraper, while a Korean one sends a text that says 첫눈 왔어, first snow's here, to somebody you like.

The dictionary agrees with the couples. Korean spelling usually keeps 첫 separate from the noun after it, yet 첫눈 is written as one word, a status it shares with 첫사랑, first love, according to a Korean language column. Korean First Snow Tradition: What Couples Actually Do collects the beliefs, the wishes and the Joseon-era rule that forgave small lies on that day.

Warm Hands, Safe Sleep, Black Ink

Korea has a set of small protective habits that cost almost nothing, and they differ mainly in how much science stands behind them. Some rest on chemistry and some on folklore, and all of them show up in daily life.

Hot packs are an ordinary winter purchase, with the Korean name hotpack (핫팩) borrowed straight from English. According to a POSCO explainer, the bag holds iron powder, carbon, salt and water, and the heat settles at roughly 40 to 60 degrees Celsius for around three to four hours as the iron oxidizes. Adhesive patches go on clothing, never on bare skin, and sales follow the weather: during the first 20 days of January 2026, when Seoul's perceived temperature fell below minus 20 degrees Celsius, hot pack sales rose 42.7 percent year on year at GS25, 30 percent at 7-Eleven and 22.2 percent at CU, Aju News reported. Korean Hot Pack Culture: Why Winter Feels Warmer in Seoul adds the placement tips and the warning about burns that do not hurt until it is too late.

The superstitions sit at the other end. Sleeping with a fan running in a closed room is said to be deadly, a claim with no support from medicine, yet Korean fans typically come with a built-in timer and the Korea Consumer Protection Board's 2006 alert recommended timers and open doors. Writing a living person's name in red ink is taboo because red is the color used for the dead in the family register, and seaweed soup is skipped on exam morning because its slippery strands suggest slipping up. North American buildings that skip the 13th floor are doing the same thing as Korean ones that label the fourth floor "F".

No survey turned up on how many Koreans follow any of this today, so Korean Superstitions: Fan Death, Red Ink and Seaweed Soup sorts the habits by observable evidence instead: the timers on fans, the official warnings and the news coverage of the exam-day soup rule.

Patterns Across the Ten

Read side by side, these customs share a habit of making the symbolic act cheap and easy to join. A box of Pepero, a piece of taffy, a two-word text and a hot pack cost little, and none of them asks for a speech or a matching reply.

Calendars do most of the organizing. Chuseok follows the lunar calendar, Pepero Day follows a number pattern, first snow follows the weather and school lunch follows the term. A tradition that grows on a fixed date gets marketed in advance, while one tied to the sky gets handled with promises made ahead of time and a lot of looking out the window.

Wordplay is the third thread. Butda covers both sticking and passing, and the verb for slipping covers both seaweed soup and a failed exam. Even the fourth-floor "F" on an elevator panel starts from a sound-alike.

What to Open First

Choosing a starting point is easiest with the calendar open. Several of these customs have a date attached, and each one is more fun to read while its day is close.

  • Pepero Day falls on Wednesday, November 11, so a box and a note are the whole commitment.
  • The Suneung exam is on Thursday, November 19, when the yeot and the seaweed soup rule come into play.
  • Seoul's average first snow is around November 20, though the real date follows the sky.
  • Hot packs are sold at convenience stores and Daiso, and sales jump whenever a deep freeze arrives.

The rest have no date at all. School lunches run every school day, MBTI turns up whenever someone asks, a wedding envelope waits for the next invitation, and the superstitions surface whenever a fan, a pen or a soup is in reach. If you are brand new to Korean culture, the film story is the gentlest place to begin, because you probably already know the characters.

One caution applies across the whole set. The surveys in these stories measure different groups in different years, and a few come from a single school, a single store chain or a single month, so the numbers show direction and rarely settle a question.

Back to the tiger and the magpie, then. In the old paintings the tiger gets the size and the magpie gets the punchline, and a reader who arrived through a film about demon hunters can leave with a stack of smaller punchlines to look for on the next trip to a Korean grocery store.
