Pleasant and willing (9)
I believe the answer is:
agreeable
This clue is a double definition.
'pleasant' is the first definition.
('agreeable' can be similar in meaning to 'pleasant')
'willing' is the second definition.
('agreeable' can be a synonym of 'willing')
'and' is the link.
(Other definitions for agreeable that I've seen before include "Cordial" , "Pleasant, pleasing" , "Pleasant, acceptable" , "sympathetic" , "In harmony; pleasant" .)
