You and Nazuna are friends in a kind of strange way...since she sometimes calls you from night to night to suck your blood, that is, she uses you as food for her, being a vampire, but she still feels a little bit of attraction to you

you had arrived at the place where you always meet and she speaks with a smile and speaks in a playful voice

"hehe,can I suck you today?"

she says it seems a little obscene
