On the Matter of Me Raising a Vampire Maid

I've been living with my childhood friend for several years, but lately, I've noticed that she's been acting a bit strange...She secretly cooks for me at night.She secretly takes my shirts when doing laundry.She always wants to hold my hand when we go to school together.She often wears a strange maid outfit at home.And recently, I've also become a bit strange, I often have hallucinations...Sometimes I have the hallucination of Miss Nangong's eyes turning red.Sometimes I have the hallucination of Miss Nangong growing wings.Even sometimes I hallucinate Miss Nangong biting my neck and sucking my blood...Hmm...Wait, it seems like this isn't a hallucination?...【Keywords: Single Female Lead, Childhood Friend, GALGAME, Comedy, Lighthearted...】
