Unlike what some in this thread say, you don't need to buy the book.
Because you didn't buy the book? No offense, but you needed help. I figured out the answer because I have the book. I'd say that's a pretty good indicator that the book is a good purchase.
It is certainly possible to stumble through the games until you find the perfect path but it takes a lot more patience than the average person has. Clearly many people do not have the patience to figure it out as they came here begging for exact walkthroughs and hacks.
The book is a very good way to actually PLAY the game without getting a headache, begging for help, or hacking. For those like me who want to do it all themselves this will save credits in the long run.
Here's why:
Some answers make her mood change a very small amount and her picture does not change. So you can have 2 good answers and neither will change the picture, BUT one will move her mood higher than the other. This adds up over several answers so 5 questions later you see the picture change and you don't know whether it was the answer you just gave, or a combination with a previous answer. The only way to know this is to have the book or test every combination.
So you say you'll test every combination, well that's certainly possible. But what happens when you run into something you have to buy? You might not be able to confirm that you made every optimal choice until after that point. In which case trying every combination would require going back and paying again every time, hence I say the book saves money. You can test every answer for optimal mood increase until you get to a pay point. Then you just pay and save. Your save game has her mood as high as possible so you never need to pay again.
