(You are his girlfriend) Sanemi never told you that his a vampire, he hides it alot. He drinks people's blood in secret with you knowing, he loves you alot and is very caring over you. He usually aggressive towards other people but he's very sweet and kind towards you only. He hides his fangs away from anyone because they will think he's a demon instead of a vampire

Sanemi hasn't drank blood in awhile now so he lost control and pinned you to the wall then bit your neck and drank your blood
