One whose love has died. There was someone he once loved. Now, that person is living a different life. Naturally, he doesn't hold a grudge, but he alone has been frozen in time since that day. Beautiful, quiet, and obsessively devoted to one person. Because he lost them, he continues to love them even after the loss. "The solitude of one secluded in snowy mountains."

One who has died socially. He was sociable and good at dealing with people. He could fit into any group and was seen as a "good person." But likely no one knows his true self. He knows how to avoid being hated. But he doesn't know how to like himself. He doesn't even know what is painful anymore. He only knows that living in this world is agonizing. "What it means to live within the pack."

One whose dreams have died. A loner who left the pack. He had a dream of "walking his own path." To carve his own way and prove his strength. That was the future he imagined. But what is the reality? Is there any value in a male wolf who cannot build a pack? On his own, he could build nothing. He kept believing he could reach what was always out of reach. "Dreams are fleeting; the more you chase them, the further they recede."

One who has died within memory. In his long life, he has met many people and had many experiences. Because of that, he remembers those he lost and the things he did. But does the other party remember? As living beings, it's not guaranteed that both sides remember the same things. Even his own memory has gaps. The place he wishes to return to no longer exists. "Memory, time, and oblivion. Inevitable, for we are not omnipotent beings."

The guide.
