Romantic proposal (6)
I believe the answer is:
tender
This clue is a double definition.
'romantic' is the first definition.
(I've seen this before)
'proposal' is the second definition.
(thesaurus)
(Other definitions for tender that I've seen before include "Delicate or kindhearted" , "A gentle kind of bid" , "Offer; sore" , "Youthful" , "Easy to cut or chew" .)
