Concerning this love, female after present (6)
I believe the answer is:
hereof
'concerning this' is the definition.
(I've seen this before)
'love female after present' is the wordplay.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'female' becomes 'f' (abbreviation).
'after' is a charade indicator (letters next to each other).
'present' becomes 'here' (both can mean in attendance).
'o'+'f'='of'
'of' put after 'here' is 'HEREOF'.
(Other definitions for hereof that I've seen before include "Concerned with" , "Of this document" , "Her foe (anag.)" , "Concerning this" , "From this (formally)" .)
