'timidly' is the definition.
Both the answer and definition are adverbs. Maybe there's a link between them I don't understand?

'upset lover welcomes us visiting new york' is the wordplay.
'upset' indicates an anagram.
'welcomes' indicates putting letters inside (in sense of 'invites in').
'visiting' is an insertion indicator.
'new york' becomes 'ny'.
'lover' anagrammed gives 'ervol'.
'ervol' going around 'us' is 'ervousl'.
'ervousl' inserted inside 'ny' is 'NERVOUSLY'.
