Randy, perhaps, for chap who's caring and supportive (3,3)

'caring and supportive' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'randy perhaps for chap' is the wordplay.
I cannot quite see how this works, but
'chap' could be 'man' (chap can mean a man) and 'man' is found in the answer.
The remaining letters 'new' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'who's' acts as a link.

Can you help me to learn more?
