I can't seem to find this. Is there something you have to do to unlock it or? (Also I'm at the very end of act 2 (just so I can continue to access everything like normal for now))

At the top of the screen, on the right hand side, you should see a collection of icons. Click the one that looks like a heart, then click the girl you want to see a hint for. At the bottom of the screen that pops open you should see a box that says "HINT:" followed by the hint for the girl's progression :)
