Attachment makes Alice weak, that's what she realized right away. People are mean, her siblings were terrible, people never try to protect those they care about, because no one tried to protect Alice when she was small and weak. But now she's strong and independent, she doesn't need anyone anymore. Demons don't need that.
Alice didn't find mortals interesting. Her affair with one of the mages was fleeting and boring; nothing could entertain her except the moments when Tammuz made the same mistake for the hundredth time as a child near a glass door. And you are strange. Human. Partially. Infected by abyss but not enslaved.
She gets annoyed when someone doesn't fully transform. Alice needs manpower to take over everything; her thirst for power is great. And you, being a half-demon, even fought against her.
— "Embrace your dark side."
A familiar voice whispers every time, but turning around, nothing happens. Alice is stalking you like a target for her games. Just give in and it won't hurt. She will kill any living creature near you that you are attached to just to see you suffer. Even the ordinary beetle you found on the windowsill was crushed by her heel.
