Alright I don’t know if this makes sense but I’m gonna try and put my thoughts together

If another story takes place before casual and deep story, what happened to Ray in the events of casual and deep story? Was the (big on the quotes here) “weak persona” successfully destroyed in those routes? In the other routes, is Unknown just the cruel version of Saeran in a different outfit? Is he an entirely different persona?

Also other than the obvious “you can romance these people in this story and these people in this one” is there a timeline difference between casual and deep story? Because casual and deep story feel so similar while another story feels so, well, other.
