Story enacted fantastically, full of love (8)
I believe the answer is:
anecdote
'story' is the definition.
(I've seen this before)
'enacted fantastically full of love' is the wordplay.
'fantastically' is an anagram indicator.
'full of' indicates putting letters inside.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'enacted' anagrammed gives 'anecdte'.
'anecdte' enclosing 'o' is 'ANECDOTE'.
(Other definitions for anecdote that I've seen before include "Short account of an incident" , "Short amusing tale" , "Date once (anag.)" , "Short entertaining story" , "Short enteryaining tale" .)
