When Seulgi tries to picture Death in her head, she half expects to see a grotesque old man, with his skin hanging low, grabbing souls and dragging them to the underworld as they cry and plead for help. Never, in her whole entire immortal life did she ever think she would end up describing Death as beautiful. 

Hades x Persephone inspired Seulrene AU. Without the kidnapping.

Also, does not follow strict ancient Greek mythology, and many other myths will be included as well.
