This is pretty sad. All she wants is intimacy but the vampire thinks shes into pain and shes too lonely and depressed to stop. At least she is adamant about controlling the boundaries, treating consent as a joke is far too common in yuri manga.
Nice to see another vampire yuri. Although it's too early to judge it's actually good or not, I am enjoying the premise. The last time this genre was given proper justice imo was in Killing Me! by Akiyama. I was depressed for 2 months when I came to know that it was cancelled.
