Some character is telling me to meet with Ran at his office, but where the hell is it?
If you've gotten the order to come to town before doing Ran's content you can reload the save before the order came into town and as long as you qualify for an event, that scene will play out before the order scene.
Later there will be a way to talk to him again if you didn't do any of his content, but that's coming sometime next year.
