You know, sometimes we use just the modal verbs to explain what we would like to say without needing put the main verb.
It is kind of that:
"I love sing and I also can."
"Eu amo cantar e eu também consigo cantar. "
You know, even though I didn't have put the verb "sing" after "can", it is completly easy to understand what I was tryna say because the verb "can" refers to this ideia. That is, "I can sing".
In this case that you have brought to us, it is the same ideia:
"I'm ready to be loved
And love the way I should".
The verb should here means "would love". So, translating:
Eu tô pronto pra ser amado. E amar do jeito que eu deveria (amar).
Hope you got it.
See you soon.
