Walk past any university gate in Seoul on the third Monday of May and the scene repeats itself: clusters of nervous-looking 19-year-olds, suspiciously large bouquets of red roses, and at least one person hiding a small department-store gift bag behind their back. That's Seongnyeonui Nal (성년의 날), Korea's Coming of Age Day — and the so-called "three gifts" (삼대 선물) tradition of roses, perfume, and a kiss is both more specific and more socially loaded than a foreign visitor might assume.
This guide breaks down what the day actually is, why exactly twenty roses (not twelve), where the ritual came from, and the etiquette expats and partners of Koreans tend to fumble in their first year here.
What Coming of Age Day actually is
Coming of Age Day, or Seongnyeonui Nal, falls on the third Monday of every May. In 2026 that's May 18. It's a national commemorative day celebrating everyone who turns the legal age of adulthood that year — but, and this is the part that throws foreigners every time, it is not a public holiday. Banks open. Schools run normally. Your Korean coworkers who are no longer 19 will, in practice, treat it like any other Monday and complain about Monday things.
The legal piece behind the date matters. According to the Korean Civil Act (민법), the age of legal majority was lowered from 20 to 19 in 2013. So today, the people being celebrated are those turning 19, gaining the right to vote, sign contracts, marry without parental consent, and buy alcohol and tobacco. Korea also separately reformed its everyday age-counting system in June 2023, abandoning the traditional "Korean age" (where a newborn is 1) in favor of international age for most legal and administrative purposes — which means the cohort celebrated on Coming of Age Day is now genuinely a year younger than it was a decade ago.
The "three gifts": roses, perfume, kiss — what each means
The modern romantic version of the day — the one most foreigners actually encounter — centers on three symbolic gifts traditionally exchanged between couples, close friends, or from parents to their newly-adult children. Each one carries a specific meaning, and the symbolism is the entire point. Skip the symbolism and you've just bought flowers.
1) Twenty roses (장미 20송이)
The flower of choice is the red rose, and the count is almost always twenty stems. The flower language (kkonmal, 꽃말) of the red rose in Korea reads as passion, devotion, and enduring love — a wish that the recipient's adulthood be lived with that same intensity. The number twenty references the traditional seumal (스물), the age of twenty, which was the legal threshold of adulthood in Korea before the 2013 reform and which still holds the symbolic weight of "fully grown" in everyday speech. Florists kept the twenty even after the legal age dropped to 19.
2) Perfume (향수)
Perfume's meaning is more poetic than it sounds in English. The Korean expression "hyanggi-ga namneun saram (향기가 남는 사람)" — literally, "a person whose scent lingers" — is a compliment, meaning someone who leaves a lasting good impression. Gifting perfume on Coming of Age Day is a wish that the new adult will be that kind of person: memorable, distinctive, leaving something positive behind in every room. It's also why the gift skews toward signature-scent eau de parfum rather than a body mist.
3) A kiss (키스)
Here's where Western media tends to over-romanticize. The "kiss" in the three-gifts tradition is, in most cases, a symbolic gesture from a parent or close family member — a peck on the forehead or cheek that marks the social transition into adulthood. In couple contexts it carries the obvious romantic reading, but the tradition itself predates K-drama framing and was originally about familial blessing. In practice today: parents lean toward a hug, friends skip it entirely, and couples treat it as the headline event of the day.
A real scene: campus on the third Monday of May
What actually happens, on the ground: by 8 AM, flower carts and pop-up rose stalls appear at the gates of universities like Yonsei (연세대), Korea University (고려대), Hongik (홍익대), and Ewha Womans (이화여대). Campus convenience stores quietly mark up their cheaper bouquets. By midday, lecture halls have a faint mixed scent of every perfume sample in Olive Young's top ten.
From experience watching this unfold near the Sinchon (신촌) area: the students celebrating are usually first-year university freshmen who turned 19 that calendar year. The bouquets travel awkwardly on the subway. Several are dropped. At least one is forgotten on a café table. Couples meet up between classes for the photo — almost always staged, almost always posted to Instagram with the hashtag #성년의날, which according to public Instagram tag counts has racked up well over a million posts in aggregate.
Parents typically handle their side of the celebration in the evening, often over a meal at home or at a restaurant. The gift here might be more practical: a wallet, a watch, a set of business-card holders — items that signal "you are now expected to function as an adult in formal settings." It's quieter than the campus version, and arguably the more meaningful half of the day.
Cost, numbers, and what people actually spend
Pricing here is not abstract. A foreign partner walking into a flower shop on the morning of May 18 with no preparation will, in practice, pay a premium. Below is a realistic range based on standard Seoul florist pricing in 2025–2026.
| Item | Typical Price (KRW) | USD (approx.) | Notes |
|---|---|---|---|
| 20-rose bouquet (basic wrap) | 40,000 – 60,000 | ~$30 – $44 | Standard florist; pre-order recommended |
| 20-rose bouquet (premium wrap, mixed greens) | 70,000 – 120,000 | ~$52 – $88 | Department store / boutique florist |
| Mid-range eau de parfum (50 ml) | 90,000 – 180,000 | ~$66 – $133 | Olive Young, Sephora Korea, duty-free |
| Designer perfume (Chanel, Jo Malone, Dior) | 200,000 – 400,000 | ~$148 – $295 | Lotte/Shinsegae department stores |
| Coming-of-Age set (florist + perfume bundle) | 150,000 – 300,000 | ~$110 – $221 | Common pre-order package in May |
For context: according to consumer-trend reporting around the day, surveys by Lotte Department Store and major florist chains have repeatedly shown a sharp spike in red-rose sales during the second and third weeks of May — historically up several hundred percent versus a normal week. That's not just couples; flower-gifting on this day skews younger and broader than Valentine's-equivalent dates in Korea.
Heads-ups, downsides, and etiquette landmines
The day looks sweet from the outside, but it carries a few traps that foreigners walk into reliably.
One more cultural nuance worth flagging: not every 19-year-old wants public celebration. Korean university culture has shifted noticeably over the past decade, and a portion of the generation now finds the Instagram-bouquet ritual performative or financially burdensome. Asking first — "do you actually want to do the whole three-gifts thing?" — is read as thoughtful, not unromantic.
Practical guide: how to handle the day
If you're an expat, partner, host family, or language-exchange friend who wants to mark the day correctly, this is the realistic playbook.
- 1Confirm the date. Third Monday of May. In 2026, May 18. Don't rely on last year's calendar — the date shifts annually.
- 2Pre-order roses by the Wednesday before. Use a local florist app like Kakao Talk Gift (카카오톡 선물하기) or Naver Smart Store (네이버 스마트스토어). Specify "스무 송이 (twenty stems)" and ask for the May 18 morning pickup or delivery slot.
- 3Choose perfume by personality, not price. A 90,000 KRW (~$66) bottle that fits the person is read as more thoughtful than a 300,000 KRW (~$221) bottle they won't wear. Olive Young and Shinsegae Department Store both run sample testers in May.
- 4Plan the gesture, not the price tag. If you're family, the symbolic kiss is forehead or cheek. If you're a partner, read the room — public displays of affection are generally low-key in Korean culture compared to many Western countries.
- 5Add one practical adult-life gift. A leather card holder, a quality pen, a name-stamp (dojang, 도장) — these are common Korean parental gifts and translate well from any gift-giver. They underline the "you're an adult now" theme more meaningfully than the bouquet ever will.
- 6Keep dinner reservations small. Korean BBQ near the recipient's campus is a safe default. Avoid hyper-formal hanjeongsik (한정식) unless the parents are running it — that's their territory.
Final thought
Here's the part that confuses every first-timer: Coming of Age Day in Korea (Seongnyeonui Nal, 성년의 날) isn't a public holiday. Nobody gets the day off. Schools don't close. The country just collectively agrees that 19-year-olds are now adults and proceeds to embarrass them with twenty roses in a department store lobby.
The "three gifts" thing — roses, perfume, and a kiss — sounds romantic until you realize the kiss is usually from a parent or, in practice, a hopeful boyfriend who has been planning this since March. Heads-up for anyone dating a Korean university freshman in May: yes, you are expected to remember. No, "I didn't know" is not a valid defense. The flower shops near major campuses like Hongdae or Sinchon will literally double their staff that morning.
One detail nobody mentions: twenty roses, not a dozen. Western florist instinct will betray you here. The number ties to the Korean age of twenty (the traditional marker before the law shifted to 19 in 2013), and a bouquet of twelve will read as "this person doesn't get it."
Skip the gas-station bouquet. Order ahead, pay the extra 10,000 KRW (~$7) for the wrap, and you'll look like you've lived here for years. Or panic-buy perfume at Olive Young at 9 PM. Both have been done.
