미안해, 그리고 고마워

The line, explained

Some goodbyes need only two things said. 미안해, 그리고 고마워 — 'I'm sorry, and thank you'. This is how an indie film ends: no speech, just the two phrases a person owes someone who stayed. Both words are in the casual register, which is itself part of the meaning. You do not say these particular forms to just anyone, and that is the point.

미안해 comes from 미안하다, 'to be sorry' or 'to feel bad toward someone'. In casual present it becomes 미안해, and that is the form you use with friends, siblings, partners — people you can be bare with. To an acquaintance you would soften it to 미안해요. To a boss, a customer, or a stranger you bumped into, you switch to a different word entirely: 죄송합니다. The three are not interchangeable, and Koreans hear the choice instantly.

그리고 is the connector 'and', but the kind that joins sentences or thoughts, not nouns. (For 'bread and milk' Korean uses particles like 와/과 or 랑.) It often carries a sense of 'and then' or 'and also', which makes it perfect here: first one thing, then the other, as if the speaker is working through a list they have rehearsed. The pause before it — the comma — is where the real emotion sits.

고마워 is 고맙다, 'to be thankful', in casual present. Watch the spelling change: the ㅂ at the end of the stem turns into 우 before the ending, giving 고마워 rather than 고맙어. Several common adjectives do this (춥다 → 추워, 어렵다 → 어려워), so it is a pattern worth spotting. Like 미안해, 고마워 is for people close to you. Polite is 고마워요; formal, for strangers and seniors, is 감사합니다.

Why does the pair hit so hard together? Because they are the two debts you carry when a relationship ends: what you did wrong and what the other person gave you. Saying both in the casual form means 'we were close, and I know it'. Swap the first half and the scene rewrites itself: 사랑해, 그리고 고마워 is a wedding; 잘 가, 그리고 고마워 is a station platform; 행복했어, 그리고 고마워 is the end credits.
