This is pretty early stage (alpha) and "Demo" version. So there isn't much content about max 1h in VR if you search all.
First interactable girl will be when you are going to farm. You met her on the way. First interactions with her is in first camp. So there is "nice" amount of story and tutorials before you can get to camp.
After 3rd camp there will be ending scene that you trigger going over the bridge.
