gyeyakdonggeo — Under One Roof, Where the Terms Come Before the Feelings
계약동거
계약동거 (gyeyakdonggeo) doesn’t mean a couple bound together by dating or marriage — it means two people living in the same home after settling the terms in advance: how long, who pays what, and the house rules. Watch even a handful of Korean dramas and you’re guaranteed to run into this setup at least once. Two people in a tight spot move in together, and somewhere in episode one they sit down facing each other with a single sheet of paper between them. The second shelf of the fridge belongs to whom, the bathroom is yours from what time to what time, laundry is separate. And the final clause is usually a given — we will absolutely never fall for each other. Viewers then sit through all sixteen episodes waiting for exactly that clause to break.
How the word was built is transparent. 계약 (gyeyak) means making a promise with set conditions, and 동거 (donggeo) means living together in one home. Stick them together and you get “living under one roof on a promise.” On the surface of the characters, there’s nothing hard about it.
The nuance, though, runs one layer deeper than the characters do. In Korean, 동거 usually refers to a romantic couple living together before marriage. So even when 계약 is attached to the front to give it a businesslike shell, the shadow of a man-and-woman relationship doesn’t disappear entirely. 계약동거 is really closer to “two people living together who have expressly nailed down that this is not romance” — and it’s precisely that nailed-down sentence that gets the story rolling. If it’s just people splitting the rent, regardless of gender or backstory, Koreans call it 룸메이트 (rummeiteu) or 셰어하우스 (syeeohauseu), not 계약동거.
One more thing. This word isn’t a headword in the Korean dictionary. It’s a compound that hardened into place through news articles and drama synopses, so if you look it up, you’ll simply find 계약 and 동거 listed separately. Here’s the point for learners to remember — the meaning is easy, but the places you can use it are narrow.
A Real Conversation
Setting: Saturday afternoon, just after viewing two studio apartments with a real estate agent. Emily, a copy of the lease in hand, plops down on the steps outside the agency.
에밀리: 아, 방값 진짜 왜 이래. 나 그냥 아는 언니랑 반씩 낼까 봐. Ugh, why is rent like this? I’m thinking of just splitting it with a friend.
준경: 오, 그거 괜찮지. 근데 규칙 미리 정해놔. 안 그러면 한 달 만에 싸운다. Oh, that works. But set the rules up front. Otherwise you’ll be fighting within a month.
에밀리: 규칙? 뭐, 계약서라도 써? Rules? What, should we write an actual contract?
준경: 어, 요즘 다 써. 청소 당번, 손님 오는 날, 나갈 때 몇 달 전에 말하기. 완전 계약동거지 뭐. Yeah, everyone does now. Cleaning duty, guest days, how far ahead you give notice before moving out. It’s basically gyeyakdonggeo.
에밀리: 야, 계약동거는 드라마에서 남녀 주인공이 하는 거 아니야? Hey, isn’t gyeyakdonggeo the thing the male and female leads do in dramas?
준경: 그것도 맞지. 근데 드라마는 마지막에 연애로 끝나고, 넌 보증금 돌려받고 끝나는 거고. That’s true too. But in dramas it ends in romance — in your case it ends with getting your deposit back.
Using It This Way Sounds Off
✗ (to a coworker who mentions living with a roommate) 아, 두 분 계약동거 하시는구나? ✓ (in the same situation) 아, 룸메이트랑 같이 사시는구나? → 계약동거 carries the built-in premise of “a relationship that could spill over into romance.” Laying this word over someone else’s living arrangement amounts to assuming a romance that isn’t there, which comes across as rude.
✗ (introducing yourself to someone you’ve just met) 저는 지금 계약동거 중입니다. ✓ (in the same situation) 저는 친구랑 집을 같이 쓰고 있어요. → This isn’t a word that states your situation plainly; it’s a word that announces a backstory. Use it with someone you’ve just met and they’ll smile awkwardly, waiting for the rest of the tale.
Example Sentences by Situation
① Recommending a drama to a friend. When you need to sum up a plot in one sentence, this word is extremely handy — it compresses the entire premise into three syllables.
이 드라마, 계약동거로 시작해서 진짜 결혼으로 끝나요. (i deurama, gyeyakdonggeoro sijakhaeseo jinjja gyeolhoneuro kkeutnayo.) This drama starts with a contract cohabitation and ends with an actual marriage.
② Grumbling lightly about drama trends. Korean viewers know perfectly well how often this setup shows up, which makes it good joke material.
요즘 드라마는 계약동거 아니면 계약결혼이야. (yojeum deuramaneun gyeyakdonggeo animyeon gyeyakgyeolhonya.) These days it’s either contract cohabitation or contract marriage.
③ Playing down your own situation as a joke. In reality you’re just sharing a place, but the rules have piled up unusually high — so you say this with a laugh. Here it pairs naturally with the frame ‘말이 ~지’ (“call it X, but…”).
말이 계약동거지, 사실은 그냥 룸메이트예요. (mari gyeyakdonggeoji, sasireun geunyang rummeiteuyeyo.) We call it contract cohabitation, but honestly we’re just roommates.
Polite vs. Casual, and Similar Expressions
계약동거 is a noun, so the word itself carries no politeness level. The politeness comes from the predicate that follows. Casual is 계약동거야 (gyeyakdonggeoya), the all-purpose polite form is 계약동거예요 (gyeyakdonggeoyeyo), and the formal form is 계약동거입니다 (gyeyakdonggeoimnida). The same split happens when you attach 하다: 계약동거 해 (hae) / 계약동거 해요 (haeyo) / 계약동거를 합니다 (hamnida).
The words that look similar all run at different temperatures.
| Expression | Temperature / Intensity | Where to use it |
|---|---|---|
| 계약동거 (gyeyakdonggeo) | Hints at a backstory; smells like a drama | Talking about dramas, or joking about your own situation. Rude when applied to someone else’s life |
| 계약결혼 (gyeyakgyeolhon) | Heavier, higher stakes | A setup that goes all the way to registering the marriage. Drama and film plots |
| 동거 (donggeo) | Heavy and private | Presumes a romantic relationship. Not thrown around about other people’s private lives |
| 룸메이트 (rummeiteu) | Plain and neutral | Anywhere. Safe even in a self-introduction |
| 한집살이 (hanjipsari) | Warm and colloquial | Among family or friends. Points at daily life rather than a backstory |
As the table shows, when you want to state your circumstances with no color attached, the default is 룸메이트. 계약동거 is what you reach for when you want to lay a layer of story on top.
Cultural Background — You Need a Pretext to Move In Under One Roof
Why 계약, of all things? To shove a male and female lead into the same house, a Korean drama needs a pretext. If they start living together for no reason at all, viewers read them as already being a couple — and then the story ends before it begins. So the writer sets down a single contract. The moment “we are not dating” is written on paper, the two of them are sharing a space while still being nothing to each other. The contract is a device for creating distance, and the process of closing that distance is the drama.
The work most often named as this setup’s ancestor is the drama Full House (KBS2, 2004), the story of two leads who begin living together on conditions, with one house between them. Countless later works have played variations on the same structure. In recent shows, the contract clauses sometimes appear right on screen as subtitles. Every time a clause breaks, the relationship moves up a notch — so the contract effectively doubles as a progress chart for the romance.
There’s a real-world side to it, too. Unmarried couples living together has become far more common in Korea than it used to be, but it’s still not a topic you bring up casually in front of your parents’ generation. So the businesslike shell of 계약 isn’t only a storytelling device — it’s also an excuse. At the same time, with Seoul’s monthly rent and key deposits being no joke, sharing a place has become a very practical choice for young people. In actual life, though, they call it 룸메이트 or 셰어하우스 rather than 계약동거 — and the sheet of paper listing cleaning duties and move-out notice periods really does go up on the fridge. The contract in the drama and the fridge memo in real life look astonishingly alike; the only difference is whether that final clause is there or not.
Today’s Quiz
Which of the following uses 계약동거 most naturally?
- (introducing yourself to someone you’ve just met) 저는 지금 계약동거 중입니다.
- (recommending a drama to a friend) 이 드라마, 계약동거로 시작해서 결혼으로 끝나.
- (introducing your parents) 저희 부모님은 30년째 계약동거 하고 계세요.
The answer is number 2. 계약동거 comes to life most comfortably when you’re summarizing a plot. Number 1 injects a backstory into a self-introduction that ought to be plain, leaving the other person feeling awkward; number 3 is a word you simply can’t use for a married couple, so it’s risky even as a joke. Today’s lesson is a single rule — use this word on stories, and use it sparingly on people.
