A wonderful time travel, falling into the world of cubes, but being involved in a thousand-year conspiracy. The rise of revenge monsters and the soul wrapped in love, the world of memories, the weird school, walking in the darkness, but longing for the light to shine around you. Can you pick up the lost things from the future? Is it true time travel or rediscovering yourself? Will he become a cowardly betrayer, or will he become a god who picks up the pieces again?
Can we add a gem country?
