위험해요

[DominicIsi]

Let's sing the campfire song!

[KanKanMikan]

(G)I-DLE are sitting beside the fire, that works too

[hassnaamoh4]

"The children sit next to the fire" was not accepted!!

[rifni]

Because it is in present continuous tense: 앉아 있어 instead of 앉아 or 앉아요

[dberks]

있어요 makes it continuous

[BobaBunny5]

What is the 의 there for?

[dsdeneve]

The fire's side

[guamacide]

although 블의 옆에 makes perfect grammatical sense, then you should be using English that reflects the Korean grammar used: "at the side of the fire." Odd but correct Korean with inconsistent English translation. Noticeable lack of native English proficiency.
