I hate when this is done.
An argument can be made that thinking about your own emotions or attempting to rationalise what you think will make you understand said feelings/thoughts better than if someone else explained it to you. I don't like it, but I accept it.
Now, when it's a matter of making a deduction out of facts, why the bloody hell are they still holding out on sharing?! Imagine Sherlock Holmes told this to Watson every time. It's a waste of time. The girl knows the solution to the problem (I actually do too but I've been trained in Da Capo BS by the too previous games, and it's not like the problem is particularly hard) but now the protagonist needs to figure it out on his own because Ricca thought that's how it should be. Flipping unicorns, in the wider context of the scene she probably could have resolved the whole drama of the route on her own before Kiyotaka even appeared if she gave more of a damn about it.
This isn't a problem of emotions, this is a problem of noticing the mistaken assumption. In no way would the impact and consequences be reduced if you flat-out explained the misconception.
