Net King + Vampire Knight + Conan + NPC + Angelic Female Protagonist
The heroine is in very bad health (never ask the hero if the heroine can eat so much.)
I tortured Sakurano, I tortured Yuki, I tortured Xiaolan, I tortured the male protagonist (after all, I am my biological mother)
The relationship between the heroine and the hero will not be smooth sailing (there will definitely be bloody plots)
There will be forbidden love (brother and sister, father and daughter)
