When and why do we use '한걸요'? Like I have seen sentences like
그대의 꿈이 너무 소중한걸요 (Your dream is so precious)
and 그대의 꿈이 너무 달콤한걸요 (Your dream is so sweet).
I looked up the meaning of 한걸요 and according to Papago app it means 'I did it'.
I am new to learning korean.
EDIT (from comments by OP): This is part of the lyrics for the song 도시의 천사들: http://gasazip.com/1242598
