Part 5: Simkung Point & Skinship — Heart-Fluttering Moments in Korean Romance
💜 고백하다 (Gobaek-hada) — To Confess
Let’s start with the moment that changes everything: 고백하다 (gobaek-hada).
고백하다 (gobaek-hada) literally means “to confess,” but in Korean romance it means confessing love.
💛 Cultural Note
In English, “confession” can mean admitting a secret or even a mistake. But in Korean dating culture, 고백 almost always means a romantic confession of love. When Koreans say “고백하다,” it signals the start of something romantic — not guilty. 💕
It’s not just a casual “I like you”; it’s the step that turns a crush into a real relationship. Imagine someone looking into your eyes and saying:
- 나 사실 너 좋아해. (na sasil neo joa-hae) → To be honest, I like you.
- 내 여자친구 해줄래? (nae yeo-ja-chin-gu hae-jul-lae) → Will you be my girlfriend?
- 내가 너 좋아해도 될까? (nae-ga neo joa-hae-do doel-kka) → Would it be okay if I liked you?
Traditionally, people expected men to confess first. But times have changed — today, many women also take the lead and say 고백 themselves.
And of course, timing matters. A snowy Christmas Eve ❄️, a quiet park bench, or walking together under city lights — these simple moments often become the most memorable stage for love.
When confessing, Koreans value two things:
담백하게 (dam-baek-ha-ge → plainly, without exaggeration) and
구체적으로 (gu-che-jeog-eu-ro → specifically).
Instead of a vague “You’re nice,” try something real and grounded, like:
“When we first met, I felt something I couldn’t explain. The way you make me laugh when I’m nervous —
that’s what made my feelings grow.”
And if the answer is no? Show 존중 (jon-jung → respect). Smile, accept it with dignity, and remember: the act of 고백 itself is brave and beautiful.
Also, a successful confession usually comes after the 썸 (sseom → flirty pre-dating stage).
Sure, 직진남 (jikjin-nam → straightforward guy) or 직진녀 (jikjin-nyeo → straightforward girl) might confess
right away, but most people wait until they’re sure the feelings are mutual. You’ll even hear the verb phrase:
썸을 타다 / 썸타다 (sseom-eul ta-da / sseom-tada → to be in a flirty pre-dating phase).
👉 And honestly, if you want to boost your chances of a successful confession, spending some time in the 썸 타는 stage to check each other’s feelings is a great idea. But be careful — if the 썸 drags on too long, the other person might get tired of waiting. ^^
📝 Quick checklist for a good 고백:
- 고백하다 = a romantic love confession, not “I did something wrong.”
- Choose simple, honest words over dramatic lines.
- Be specific about what you like: their laugh, their kindness, their presence.
- Pick thoughtful timing & atmosphere that feel natural for both of you.
- Respect the answer — yes or no — with 존중 and maturity.
- Let 썸 build some connection, but don’t let it drag on forever without clarity.
🌟 Special Confession Timing
Especially among teens and people in their early 20s, there are certain days that almost invite confessions:
-
발렌타인데이 (bal-len-tain-de-i → Valentine’s Day) — Feb 14.
Globally it’s known as a day when couples exchange gifts, but in Korea it’s often seen as the day women give chocolate (and sometimes a confession) to men. -
화이트데이 (hwa-i-teu-de-i → White Day) — Mar 14.
A month later, men give candy back… and sometimes share their own 고백 (confession). -
빼빼로데이 (ppae-ppae-ro-de-i → Pepero Day) — Nov 11.
A fun, playful day when anyone can give Pepero sticks to someone they like. It’s lighthearted, but can also carry a hidden “I like you” message. 💕 - 고백데이 (Gobaek Day) — Sep 17. It’s not an official holiday, but many young people love it because if you start dating on September 17, your 100th-day anniversary lands exactly on Christmas Day. That’s why some see it as the perfect date to confess and make the beginning of a relationship feel even more special. 🎄💛
Not sure when the right time to confess is?
Then these days can be the perfect little excuse to finally say it. 😉
💜 사귀자 (Sagwija) — Let’s Be a Couple
In Korea, 사귀자 (sagwija) is the magic word that turns 고백 into an actual relationship.
💛 Cultural Note
In English, 사귀자 is often translated as “Let’s date,” but in Korean it carries more weight — closer to “Let’s officially be a couple” or “Will you be my girlfriend/boyfriend?” It’s not about just going out; it’s about officially starting a relationship. Without saying it, the other person might wonder: “Are we a couple? Or still just 썸 (sseom)?”
📺 K-Drama Example: Our Unwritten Seoul
In Episode 7, Ho-su finally confessed to Mi-ji. He spoke honestly about how much he liked her, the qualities he admired, and the reasons he hadn’t had the courage to confess until now. Then, holding her hands, he said:
“미지야, 니 마음이 좀 더 편할 때, 내가 좀 더 나은 사람일 때,
그때 제대로 해야겠다 싶어서 계속 참았는데,
지금 말할게. 좋아해. 되게 많이.”
= Mi-ji, I kept waiting until your heart was more at ease, until I became a better person. I kept telling myself I should do this properly, so I held it in… but I’ll say it now. I like you. Very much.
It was 담백 (plain), 구체적 (specific), and 진솔 (genuine). But there was one thing missing: 사귀자.
So Ho-su assumed they were together, while Mi-ji kept wondering: “So… are we really a couple, or still just friends?” 😳❓
👉 That’s why saying 사귀자 is so important. It gives clarity and prevents heartache.
Some people even add: “오늘부터 1일이다.” (o-neul-bu-teo il-il-i-da → From today, it’s Day 1).
And if you’re unsure, you can ask:
“그럼 우리 오늘부터 1일인 거야?”
(geu-reom u-ri o-neul-bu-teo il-il-in geo-ya? → So… are we officially Day 1 now?).
📺 Of course, True Beauty (여신강림) Episode 8 shows another side.
Su-ho (Cha Eun-woo) confessed directly with the line:
“내가 좋아하는 사람, 너야!”
(nae-ga jo-a-ha-neun sa-ram, neo-ya → The person I like… is you!)
and sealed it with a kiss under the stars. Without even saying “사귀자,” the scene made it obvious to
viewers that Su-ho and Joo-gyeong were now a couple.
But outside of K-dramas, things aren’t always that straightforward. If the 썸 (sseom → flirty stage) is too
short, or if feelings aren’t clearly confirmed, skipping those actual words can leave one person confused —
just like Mi-ji in Our Unwritten Seoul.
That’s why in real life, many Koreans still prefer to hear the obvious words like:
사귀자 (sagwija → let’s be a couple) or 사귈래? (sa-gwil-lae? → Do you want to be my
girlfriend/boyfriend?).
If you enjoyed Ho-su & Mi-ji’s story, Our Unwritten Seoul is full of
gentle, realistic moments about modern relationships in Seoul.
If you want to relive the butterflies of sseom, heartfelt confessions, and that first-love excitement, this drama won’t disappoint.

💜 From 썸 to 연애 — Why “사귀자” Matters
The line between 썸 (sseom → flirty pre-dating) and 연애 (yeonae → official dating) can be very thin. That’s why Koreans prefer clear words like 사귀자.
If you’re curious about expressions related to the sseom stage, check out
👉
Part 1: 썸 (Sseom) & 플러팅 (Peulleoting) — The Ambiguous Stage
Once 고백 is successful, you’re no longer 썸남 (sseom-nam → guy you’re flirting with) or
썸녀 (sseom-nyeo → girl you’re flirting with).
You become
남자친구 (nam-ja-chin-gu → boyfriend) and
여자친구 (yeo-ja-chin-gu → girlfriend).
And 남자친구/여자친구 are different from 남사친 (nam-sa-chin → guy friend) or 여사친 (yeo-sa-chin → girl friend).
남사친 literally means 남자사람친구 (nam-ja-sa-ram-chin-gu → male-person friend), and 여사친 is
여자사람친구 (yeo-ja-sa-ram-chin-gu → female-person friend). They’re just friends, not lovers.
📺 K-Drama Storytelling — Our Unwritten Seoul
Think of Ho-su and Mi-ji. After that long-awaited confession — and after clearing up the
confusion about whether they were really dating or not — they finally became
남자친구 (nam-ja-chin-gu → boyfriend) and
여자친구 (yeo-ja-chin-gu → girlfriend) — an official couple. 💕
Mi-ji also has Gyeong-gu. But he’s her 남사친 (nam-sa-chin → male friend). They laugh and hang out comfortably, but there’s no romance there, only friendship.
Then there’s Se-jin and Mi-rae. They take care of each other, lean on each other, wait for each
other, and can’t help but be curious about each other. They’re
썸남 (sseom-nam → guy you’re flirting with) and
썸녀 (sseom-nyeo → girl you’re flirting with), living in that flirty in-between stage — so will
Se-jin finally confess to Mi-rae?
Through these three pairs, you can feel the difference:
썸 is exciting but uncertain,
남사친/여사친 is safe but just friends,
and 남자친구/여자친구 is the real beginning of romance. 💕
❤ Quick List
- 남자친구/여자친구 (nam-ja-chin-gu / yeo-ja-chin-gu) — boyfriend/girlfriend
- 남사친/여사친 (nam-sa-chin / yeo-sa-chin) — male/female friend, not romantic
- 썸남/썸녀 (sseom-nam / sseom-nyeo) — guy/girl you’re flirting with
💛 Cultural Note
In Western dating, couples sometimes “slide into” a relationship without clearly saying it.
In Korea, though — especially among teens and people in their early 20s — 고백 (gobaek → confession) + 사귀자 (sagwija → let’s date) are seen as essential steps. That clear moment becomes 오늘부터 1일 (o-neul-bu-teo il-il → Day 1), the base for celebrating milestones:
- 100일 (baek-il) → Day 100
- 200일 (i-baek-il) / 300일 (sam-baek-il) → Day 200 / 300
- 1년 (il-nyeon) → Year 1, and beyond
👉 As couples get into their 30s and 40s, things can feel different: many start dating naturally without tracking the exact date. But for younger couples, saying 사귀자 isn’t just about clarity — it’s also about enjoying those shared milestones and memories. ^^

💜 FAQ — 고백, 사귀자 & Korean Dating Culture
-
Q. Is 고백하다 the same as just asking someone out?
A. Not exactly. 고백하다 (gobaek-hada) is more than “Do you want to hang out?” — it’s a clear love confession. It usually means “I like you romantically and I want us to be a couple.” -
Q. Do Korean couples always say “사귀자”?
A. Not always, but many people still prefer it, especially teens and people in their 20s. Saying 사귀자 (“Let’s be a couple”) or 사귈래? (“Do you want to be my boyfriend/girlfriend?”) makes it clear that you’ve moved from 썸 into 연애. -
Q. Can you become a couple in Korea without a clear confession?
A. It happens, especially for people in their 30s and 40s who start dating naturally. But for younger couples, 고백 + 사귀자 is still seen as the “official start,” and many feel uneasy if that moment never happens. -
Q. How long should the 썸 stage last before confessing?
A. There’s no fixed rule, but many people expect some time to get to know each other — texting, calling, going on casual dates. If the 썸 goes on too long with no confession, the other person may feel tired or unsure and slowly give up. -
Q. Is it okay for women to confess first in Korea?
A. Absolutely. Traditionally, men were expected to confess first, but these days many women also make the first move. A sincere, 담백한 (plain and honest) 고백 is appreciated no matter who says it. 💕 -
Q. Do all Korean couples celebrate 100일 and every milestone?
A. Not everyone. 100일 (Day 100) and other “Day” milestones are especially popular among younger couples. As people get older, they often stop counting exact days and focus more on anniversaries by year, but the idea of “오늘부터 1일” (Day 1 from today) still feels very romantic.
💜 Final Thoughts
From simkung moments and gentle skinship to brave confessions and clear “사귀자”, Korean romance vocabulary isn’t just cute slang — it reflects deep cultural values around comfort, clarity, and emotional honesty.
Once you understand words like 고백하다, 사귀자, 썸, and 연애, K-dramas and dating shows feel completely different. Every line, every hesitation, and every anniversary suddenly makes sense on a deeper level.
And if you ever find yourself on a 소개팅 (blind date) in Korea, remember: love doesn’t always need a grand event. Sometimes, one sincere 고백 and one clear 사귀자 — plus a warm smile — are enough to change two people’s lives forever. 💕
With love,
Hangeulia 😊
