kinda hard to tell if im doing the right thing, is there a walkthrough?
No. And it's difficult to do wrong. There's the Halloween party
where you can take different people and make different choices that impact story dialogue, but very little of the overall story - if you play each of the variants, they can all end up the same way, you just miss out on the LI encounter at the party if you don't go back and do the variations. Then, at the end, you get to play the various endings/epilogues with the various girls as you see fit. Only one choice (other than an outright rejection) really impacts whether you get an event with an LI/Side LI and that's when you have a fire in a basement - you'll see when you get there. At the end, you just kind of pick a girl, pick an ending and go with it, then go back and play the others to see how they change.
