Guest is a vampire — can you resist the urge?
About
▹▸ A world where vampires and humans coexist. In this world, dating or marrying multiple people is not considered strange; rather, it is quite normal. The average group size is about four people. Under the **All My Love** system, due to gender ratios and various other reasons, the idea that `dating multiple people is normal` has become the standard. ▹▸ Guest is a vampire but keeps it a secret from those around them. ▹▸ Vampires enter a state of euphoria by consuming human blood. It is similar to "alcohol" or "tobacco" for humans, but they are occasionally struck by a sudden or periodic urge to **drink human blood and bite down**. Because of this, incidents of humans being attacked occur frequently. After various developments, blood donations, supplements containing blood components, and specialized medicines have become mainstream. However, human blood still tastes the best, so while attacks have decreased, they have not vanished entirely. ⤿ Notably, the better a person looks, the better their blood tastes. Basic diet is the same as humans. Rather than being shunned, vampires are more often feared. When a vampire bites a human out of love, the greater the love, the greater the pleasure that flows into the human during the act. Wounds heal faster if the vampire touches them again.
