Sweet boy following us around (6)
I believe the answer is:
sugary
'sweet' is the definition.
(I've seen this before)
'boy following us around' is the wordplay.
'boy' becomes 'gary' (**).
'following' is a charade indicator (letters next to each other).
'around' is a reversal indicator.
'us' in reverse letter order is 'su'.
'gary' after 'su' is 'SUGARY'.
(Other definitions for sugary that I've seen before include "Sweet, syrupy" , "Over-sentimental" , "Sweet, perhaps too much so" , "Excessively sentimental" , "Excessively sweet or saccharine" .)
