Can someone give me a walkthrough for the Captain please I want to know where to find him so far in the story so I can be put on his route please and thank you
There's no real walkthrough to be given! There's no routes for the different characters if you want to romance them; just spend time with them naturally and you'll discover what they're all about. There are ways to get in real good with some characters much earlier, but they require a lot of specific effort... as they should to get in their pants so fast!
Long story short: there's no romance routes, so take your time and enjoy their company!
