Memories

It's a World Meeting like any other. The same nations fighting and arguing when something unusual happens.

A bright light engulfs the room and then a large screen appears.
A note stating that the screen is to show the memories of each nation is found.

After the nations decide that watching the memories would be the best thing to do, what will happen? What memories will be recovered and forgotten pasts be remembered? Or should the past stay in the past?

This book will not contain pairings, sorry. Friendships and family relationships only.
