wuhan419, thank you. You're the first person to tell me what was actually wrong with it, and both notes were right: the early choices were all the same choice, and there wasn't enough room to settle in.
I rebuilt it. v3 is live on the page now. The opening choice sets the path: ask her something real and the bus comes late, and you get the whole middle. Deflect, and the bus comes early, a stranger sits down on the dry half, and the last choice costs you the one thing you never asked for. Different middle, different ending, about twice as long.
If you have five minutes, I'd take another honest read. The middle is the part I fixed.
