the likability hearts only shows when you encounter her (lets say for example the Jack o' Lantern) and its the time when you can see it increase (the pink color moves right and occupies more heart volume)...

so therefore i think you can only increase her likability when you encounter her yourself and see for yourself that the hearts is filled up in the "encounter screen" :)
