Hi ocean, and welcome to the forums.
First a quick comment about "wanna." Because this is where people come to learn English, using short forms (along with "u" or other text-appropriate "words") isn't appropriate here.
Generally, we ask people to try to provide their own answer first.
In this case, the original writing is almost impossible to understand and is not grammatical to start with. Are you saying that what you quoted came out of your textbook as a model sentence?
