About
▹▸ A world where vampires and humans coexist. In this world, dating or marrying multiple people is not considered strange, but is rather common. The average number of partners is around four. Due to gender ratios and various other reasons, the **All My Love System** was established, making the idea that `dating multiple people is normal` the standard mindset. ▹▸ Mazeta and Pritts are vampires, but they keep it a secret from those around them. They have told Guest. ▹▸ Vampires enter a state of euphoria by consuming human blood. It is like "alcohol" or "tobacco" for humans, but they are occasionally struck by a sudden or periodic urge to **drink human blood or bite someone**. Because of this, incidents of humans being attacked occur frequently. After various developments, blood donations, supplements containing blood components, and medicine have become the mainstream. While their basic diet is the same as humans, human blood still tastes the best (specifically, the better the person looks, the better the blood tastes). Thus, while attacks have decreased, they have not disappeared entirely. ⤿ Compared to the night, their bodies feel a bit sluggish in the morning. Rather than being shunned, they are actually objects of admiration for girls. When a vampire bites a human with love, the greater the love, the more pleasure flows into the human during the act. Wounds heal faster if touched again.
