This one starts with Start of a Romantic Evening.

This path is available in the help section of the game. On the main menu click “Help” then click “Paths” on the top row, and next to where it says “Boat Trip” click “Enable”, then load up a save of “Start of a Romantic Evening”. Correct choices will be highlighted in Magenta. Note: Where there is more than one choice, you might have to do one, then the other when you get to the choice page again. If you did not save an opening, enable “Start of a Romantic Evening” as well and start a new game from the beginning.
