How to Say "I Love You" in Korean (with Romance Levels)

"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, how to write it in Hangul, 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.

How to write 사랑해 (saranghae) in Hangul

'I love you' in Hangul is 사랑해 — three syllable blocks read left to right. Each block stacks its letters in the standard Hangul order, and together they spell saranghae. Here's the breakdown:

• 사sa

  ㅅ (s) + ㅏ (a)

  First block — consonant on the left, vowel on the right.

• 랑rang

  ㄹ (r) + ㅏ (a) + ㅇ (ng)

  A bottom consonant (받침) ㅇ gives the -ng sound.

• 해hae

  ㅎ (h) + ㅐ (ae)

  Put together: 사 + 랑 + 해 = 사랑해.

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 love you too" and "I love you so much"

Once 사랑해 is in your pocket, these are the natural follow-ups — answering it back, or turning up the intensity.

• 나도 사랑해nado saranghae

  I love you too

  나도 = 'me too'. Polite: 나도 사랑해요. The standard reply to 사랑해.

• 많이 사랑해manhi saranghae

  I love you so much

  많이 = 'a lot'. 너무 사랑해 (neomu saranghae) works too — 'I love you so much'.

• 내 사랑nae sarang

  my love

  A sweet term of address: 내 ('my') + 사랑 ('love').

"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'.

Dating words you'll want next

Once the confession lands, this is the relationship vocabulary that comes up first.

• 남자친구 / 여자친구namjachingu / yeojachingu

  boyfriend / girlfriend

  Often shortened to 남친 / 여친 in casual speech and texts.

• 사귀자sagwija

  Let's date / let's go out

  The actual line for 'will you be my boyfriend/girlfriend?' — 사귀다 = 'to date'.

• 뽀뽀 / 키스ppoppo / kiseu

  peck / kiss

  뽀뽀 is a cute little peck; 키스 (from English 'kiss') is a real kiss.

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.
