Love story (7)
I believe the answer is:
romance
'love story' is the definition.
(I know that love story can be written as romance)
This is all the clue.
(Other definitions for romance that I've seen before include "Make up stories - Menorca (anag)" , "Love affair; medieval tale" , "Affair of the heart" , "Sentimental affair in Menorca" , "Love-story" .)
