"I love you" is probably the first emotional phrase most K-drama and K-pop fans want to say in Korean. But Korean doesn't have one fixed translation — the phrase changes depending on how polite you're being and how strong your feelings are. Get the level right and it lands perfectly; get it wrong and it can feel either oddly stiff or too intense too soon. Here's exactly how to say it, and what to say instead while feelings are still new.
사랑해 / 사랑해요 / 사랑합니다 — the three levels
All three come from the verb 사랑하다 (saranghada, 'to love'). The ending is what changes the politeness — the same 존댓말 vs 반말 logic that runs through all of Korean.
- 사랑해saranghae
I love you (casual / 반말)
For a partner, family, or someone you're close to. The everyday romantic version.
- 사랑해요saranghaeyo
I love you (polite / soft)
The -요 ending keeps it warm but a touch more respectful or gentle. Very common too.
- 사랑합니다saranghamnida
I love you (formal)
Heartfelt-formal — weddings, public declarations, a serious message, or to elders.
If you only remember one, remember 사랑해. It's what couples actually say to each other day to day. Reach for 사랑해요 when you want to sound a little softer or you're not yet on fully casual terms, and save 사랑합니다 for big, formal moments.
Love vs like: 사랑해 vs 좋아해
This is the distinction that trips learners up most. 사랑 (sarang) is love; 좋다/좋아하다 (jota / joahada) is to like. Confessing a crush in Korean almost always starts with 'like', not 'love'.
- 좋아해joahae
I like you (casual)
The classic confession. Lighter than 사랑해 — how most relationships begin.
- 좋아해요joahaeyo
I like you (polite)
A polite confession, e.g. to someone you don't yet speak casually with.
- 너를 좋아해neoreul joahae
I like you (with 'you' spelled out)
너 (neo) = 'you' casually. Adds emphasis to the confession.
"I miss you" and other sweet phrases
- 보고 싶어bogo sipeo
I miss you (lit. 'I want to see you')
Add -요 for polite: 보고 싶어요. Hugely common between couples.
- 너밖에 없어neobakke eopseo
I have no one but you
A sweet, slightly dramatic line straight out of every K-drama.
- 내 거야nae geoya
You're mine
Playful and possessive — casual register.
Terms of endearment (애칭)
애칭 (aeching) are pet names. Koreans use them a lot once a couple is comfortable. A few you'll hear constantly:
- 자기야jagiya
Honey / babe
The go-to pet name between dating couples. 자기 + the affectionate -야.
- 여보yeobo
Dear / darling (married couples)
Traditionally between spouses. Saying it implies a settled, married relationship.
- 애기야aegiya
Baby
Cute and affectionate; literally 'little baby'.
Reading the register — why it matters
The hardest part isn't the words — it's knowing which level to use and when to move from 좋아해 to 사랑해, or from 사랑해요 to 사랑해, as you get closer. That switch from polite 존댓말 to casual 반말 is a real, felt moment in a Korean relationship. The best way to develop an instinct for it is to practice in low-stakes conversation. In our AI character chat, characters speak to you at different politeness levels and respond as the relationship warms up, so you can feel exactly when 사랑해요 becomes 사랑해 — without the nerves of a real first confession.
