South Asian region where boy meets girl (6)
I believe the answer is:
bengal
'south asian region' is the definition.
(I've seen this before)
'boy meets girl' is the wordplay.
'boy' becomes 'ben' (boy's name).
'meets' says to put letters next to each other.
'girl' becomes 'gal' (synonyms).
'ben'+'gal'='BENGAL'
'where' acts as a link.
(Other definitions for bengal that I've seen before include "cat" , "Beautiful endangered tiger of India" , "Bay of -- forms part of the Indian Ocean" , "Bay of - lies between India and Myanmar" , "region of India" .)
