I Would Want To See You One Last Time.

Two young women, high schoolers, one aware of magic and the other is not. Winter, our unaware human, meets the Vampire, Maria. Maria tells our main character, Winter, about all this magic. She doesn't believe it, how could she? Until she has a first-hand experience with it. An accidental bite from Maria. Many arguments and supernatural occurrences later, she finally believes. Now that she does, Winter can't stop seeing it. It's everywhere. It's in her blood, how will she get it out?
Through this, there's another thing, the two of them have their difficulties. Maria hates herself for being a blood-drinking Vampire and hurting others. While Winter does not want to make it past 30. She sees no point. Maria tells Winter that she will keep this information remembered. Maria tells her she will be the one to do that for her. The night before her 30th birthday.
But will she actually do it?
