Heart of Mine
After the death of their parents and the torture they endured during their enslavement from a cult, Ciel made it his mission to make sure his sister (y/n) didn't remember a thing. Once he employed Sebastian he instructed the demon to erase (y/n)'s memory of the nights they spent tied up in a cage and leered at by perverse men. Through the years the demon has kept a close eye on the siblings, more so the way Ciel's affections have changed for (y/n). Even the young Earl is unaware of his own abnormal feelings for his beloved sister. His upcoming marriage to Elizabeth has these feelings arising.
