I think there is something not right in the walkthrough.
For day 14 it expects a library scene which seems to require you have visited the library twice (to have 50 int), but the guide only mentions the library on day 9 and then as an option on day 10, but there it clearly favors the bar waitress option.
I tried to fix this somehow with a save editor, but the game seems to not register changed intelligence or the attempt to increase stamina to do both things...
