Betrayed by the gods and damned to hell.. you, the angel-demon hybrid San, were banished from his home amongst heaven.

For centuries you had been locked away in a long forgotten building where the gods had punished those who defied them.

Wooyoung was an explorer and also an angel.

The times were now modern and you were still banished, your story was a legend. Wooyoung had heard of your legend and wanted to find out for himself if it was true.
