A heartless romance and trouble for lover (10)
I believe the answer is:
aficionado
'for lover' is the definition.
(I've seen this before)
'a heartless romance and trouble' is the wordplay.
'heartless' means to remove the middle letters.
'romance' becomes 'fiction' (both can mean a story).
'and' is a charade indicator (letters next to each other).
'trouble' becomes 'ado' (both can mean bother or commotion).
'fiction' with its middle taken out is 'ficion'.
'a'+'ficion'+'ado'='AFICIONADO'
(Other definitions for aficionado that I've seen before include "ardent follower" , "Fan (Sp.)" , "Expert person" , "Informed enthusiast" , "Admirer" .)
