나온 is the past noun-modifying form of 나오다. In this sentence, it means the drama that the actor appeared in.

• 나온 드라마 = the drama that (someone) appeared in
• 나오는 드라마 = the drama that (someone) is appearing in / appears in

For a finished work or a specific drama someone was in, 나온 드라마 is the natural choice.

This is a Korean relative clause.

Korean puts the describing clause before the noun:

• 그 배우가 나온 = that actor appeared in
• 드라마 = drama

So together:

• 그 배우가 나온 드라마 = the drama that actor appeared in

Then 는 marks that whole noun phrase as the topic:

• 그 배우가 나온 드라마는 = As for the drama that actor appeared in...

This is very different from English word order, so it often feels backward at first.

Here, 그 배우가 marks the actor as the subject of 나오다 inside the relative clause.

So the structure is:

• 그 배우가 나오다 = that actor appears / appeared
• 그 배우가 나온 드라마 = the drama that that actor appeared in

Using 는 instead of 가 would add a contrastive or topical nuance, like as for that actor..., which is usually not needed here. 가 is the neutral, natural choice.

Because each part has a different grammatical role.

• 배우가: the subject inside the relative clause
  → the actor is the one who appeared
• 드라마는: the main topic of the sentence
  → as for the drama
• 결말이: the subject of 슬프다
  → the ending is what is sad

So the sentence has layered structure:

1. 그 배우가 나온 modifies 드라마
2. 드라마는 becomes the topic
3. 결말이 슬프지만 comments on that drama
4. 다시 보고 싶어 gives the speaker’s reaction

This is very normal in Korean.

결말이 is the most neutral way to say the ending is sad.

• 결말이 슬프다 = the ending is sad

If you said 결말은 슬프지만, it would sound more contrastive, like:

• As for the ending, it’s sad, but...

That version is possible, but 결말이 is more straightforward here.

-지만 means but, although, or even though.

It connects two ideas that contrast:

• 결말이 슬프다 = the ending is sad
• 다시 보고 싶어 = I want to watch it again

So:

• 결말이 슬프지만 다시 보고 싶어
  = The ending is sad, but I want to watch it again

With adjectives, you attach -지만 directly to the stem:

• 슬프다 → 슬프지만

This comes from the grammar pattern -고 싶다, which means to want to do.

Formation:

• 보다 = to see/watch
• verb stem: 보-
• 보고 싶다 = to want to watch
• 보고 싶어 = casual speech form of 보고 싶다

So:

• 다시 보고 싶어 = I want to watch it again

This is one of the most common ways to express personal desire in Korean.

싶어 is casual/informal speech.

Compare:

• 보고 싶어 = casual
• 보고 싶어요 = polite
• 보고 싶다 = dictionary form / plain written style

So the sentence sounds like something you might say to a friend. If you wanted to make it polite, you would say:

• 그 배우가 나온 드라마는 결말이 슬프지만 다시 보고 싶어요.

In Korean, the subject is often omitted when it is obvious from context.

With -고 싶어, in a normal statement, the subject is usually understood as I.

So:

• 다시 보고 싶어 naturally means I want to watch it again

Korean does not need to say 나는 unless there is a reason to emphasize or contrast it.

The object is omitted because it is already clear from context.

The sentence first introduces:

• 그 배우가 나온 드라마는 = as for the drama that actor appeared in

Then later:

• 다시 보고 싶어 = want to watch again

So the understood object is that same drama:

• (그 드라마를) 다시 보고 싶어

Korean often leaves out objects when they are obvious.

It can mean either, depending on context.

Since the object is 드라마, the most natural English translation is:

• I want to watch it again
• I want to rewatch it

Literally, 보다 is broad and can mean see, watch, or look at, but with TV shows and dramas, watch is the best choice.

Yes, 나오다 literally often means to come out or to appear, but in Korean it is also commonly used for people appearing in media.

So:

• 그 배우가 나온 드라마 = the drama that actor appeared in

This is very natural Korean. A more formal alternative is:

• 그 배우가 출연한 드라마

Both mean roughly the same thing, but 나오다 is very common in everyday speech.
