Love movie nobody catches involving pair exclusively (3-2-3)
I believe the answer is:
'involving pair exclusively' is the definition.
I can't judge whether this definition defines the answer.
'love movie nobody catches' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'movie' becomes 'ET'.
'nobody' becomes 'no one' (not a single person).
'catches' is an insertion indicator.
'et' placed inside 'noone' is 'netoone'.
Can you help me to learn more?
(Other definitions for one-to-one that I've seen before include "meeting?" , "T?te-?-t?te" , "Corresponding uniquely, each to another" , "12:59" .)
