The Inner Workings of the Mind

Way up in the mountains where Sakura flowers are painted blue instead of pink, one lone mansion stands deserted as it has been for many years. No one know who lived there before and no one has even gone up to it for as long as its has been empty. So there it sits, alone and with no purpose. No one lives there in it's walls now...but what about the past? Could the years of the past still linger inside it's walls? Who lives within this past?
