Thank you KiGa, though, sadly, I did.
It links me to this...

... which if you check... on Day 9... Line 12... it says "Choose options"... not choose options 1 and 3, or 2 and 3, or whatever.
You can only pick 2 before the game forces you to move on. Most of the time, the walkthrough is very specific ("doesn't matter", "choose 2 or 4", etc...). I'm just worried that there's text missing after "choose options" since the poster of the walkthrough often just puts "doesn't matter" when it... well... doesn't matter.
I'm just worried that I have to replay half the game if I choose wrong. There's a lot of posts of "I can't get the good ending" and... this might be why. Or it might be nothing. I don't know... it's why I asked.
I do appreciate you pointing out the OP, KiGa. Many people don't check it. Thanks.
