How cartoon couple were attracted to each other? (5,8)

I believe the answer is:

drawn together

I'm a little stuck... Click here to teach me more about this clue!

'how cartoon couple were' is the definition.
I can't judge whether this definition defines the answer.

'attracted to each other?' is the wordplay.
'attracted' becomes 'drawn' ('draw' can be a synonym of 'attract').
'to each other?' becomes 'together' (I can't justify this - if you can you should believe this answer much more).
'drawn'+'together'='DRAWN TOGETHER'

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
