Romantic adorer (7)
I believe the answer is:
admirer
'romantic adorer' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for admirer that I've seen before include "A young lady's beau - he thinks she's great" , "Married to one who cherishes" , "sweetheart" , "One who thinks highly or romantically of" , "Suitor; devotee" .)
