Im just curious of playing this game because im new and i really dont understand on what i need to do
Hi there, sorry the late response! (Internet issues in Canada :S)
There isn't a game guide, as I don't really have time for that at the moment. But you should be able to check the Backpack Icon > Quest Log > and then click on any active quest for a hint on what to do next.
When in doubt, talk to people! Their conversational choices will change all the time.
