Can someone answer a few questions for me?
First, what is the real impact of the initial choice between Gary or Charlie? From what I've found, I understand that Gary gives me more scenes, while Charlie is more about spying. I gathered that if I choose one, I won’t be able to integrate with the other anymore, but after choosing Gary, I can still talk to Charlie and still have options for spying.
Second, does the first choice between walking or taking the bus block one of the characters for me? (And to follow up, is there any choice in the game that blocks one of the girls?)
My third question is about dating Natalie. Do I need to be on a specific route to be able to date her, or does it not matter? Is there a route where Natalie has never dated Gary?
And my last question, later in the game, do we need to choose one of the girls as our main girlfriend and leave the others as mistresses or side chicks, or can we go for a harem route?
