Time flies, what has been taken away, and what has been left behind?
Time can hide all traces of what happened. What can truly prove what happened is not a dream, only the memory in the mind.
Memories that are truly worth guarding will not be forgotten by the passage of time.
(Well~ to put it simply, it is the memoirs of everyone in VK. Each volume is the memory of one person. You can skip the characters you don't want to read)
