HP: the Eternal Night Brought by the Raven

[Serious private setting] [Nurture system] [Guiding lovers] [Strong men and stronger women] [I think Snape was suffering too much and wanted someone to support him through the storm, so I came up with this work] Under the cobweb-like thread of fate, Snape's life was rewritten. He was no longer the gloomy half-blood prince, but the heir whom she had nurtured. She picked him up from the dust of Spider-Ends and gave him grace and edge. She is arrogant and frivolous, playing in the world, and can abandon everything. She can only tie her affection and paranoia that span life and death to him alone. Memories of the current life broke through the seal of the gods like a tide. When Voldemort's shadow began to envelope the magical world, Snape stood at the crossroads of destiny. This time, he will no longer live to atone for his sins. In the game of light and darkness between pure blood and mixed blood, and under the cruel test set by the gods, he will use what he has learned throughout his life as an edge to stand side by side with the only soul that can touch his cold heartstrings. When the bat learns to cherish the only rose, and when the calculating soul begins to protect it at all costs, the whole world will make way for it.
