In some cases, you may need to repeat some of the hints. The key is to pay attention to the stat gains for each hint. If you're not getting any new stat gains for something, do the next hint in line until the hint or hints change.
You can look in the phone to see where each character is at, stat wise.
Are these the stars that's mentioned in this walkthrough?
The walkthrough is outdated as the stats no longer include the stars. They were removed around 2017/2018 when the game was overhauled in version 0.8.3. A lot of changes were made to the game, including to the hint/stat system.
Ok so this walkthrough is pretty much useless and don't even need it. Pretty much just follow what the little hints say when you put your mouse over the girls picture at the bottom. Increase their love, lust and BDSM points (for some) as you play so you can get everything that's available?
Yes, that's correct. There are date guides which I have posted on here some time ago, so they will be of use to you when you are able to date some of the girls. Having said that, if you still need help or are stuck on something, just ask.
You have to base your response on what she says, so the 'correct' response changes each time. Here is the guide.
"if she says she's not sure - order first to give her time to decide"
"I have no idea" reads to me like she doesn't know at all. That's not unsure.
