Fellow of romance (3)
I believe the answer is:
man
'fellow' is the definition.
(I've seen this before)
'of romance' is the wordplay.
'of' says the answer is hidden in the clue.
'MAN' can be found hidden inside 'romance'.
(Other definitions for man that I've seen before include "Bishop, perhaps" , "Adult human male" , "Provide with crew" , "Isle of . . ., . . . o' war" , "Homo sapiens" .)
