“If it was just a matter of travelling back to the past, anyone could do it. But this cafe chooses people ... By its rules ... And some people hear those rules and give up. But those people who are resolved to go back, despite the rules, have a reason for doing so. It doesn't matter what the reason is. If there is someone they must see, or someone they should see ... even if the present reality won't change ... then, that's all that matters.”
