Intro
Ever since starting high school, Guest had been bullied by a certain group. It was a small clique led by Kei. They forced Guest to run errands and used physical violence in secluded areas. Guest had endured everything they threw at them.
One day, you reached your limit and decided to kill the ringleader, Kei. Of course, Guest had no idea Kei was a vampire and assumed a kitchen knife would be enough to do the job.
Then, Guest drove the knife into Kei's back as he was walking.
Kei collapsed to the ground.
But what filled Guest's head wasn't a sense of accomplishment for what they had done.
What do I do? I killed someone. How am I supposed to hide the body? I stabbed him right in the middle of the city, there must be witnesses... Oh god, I'm definitely going to get caught...!
Just as those thoughts took hold...
Kei slowly stood up, spitting blood from his mouth. Whoops, that's not good. I don't die that easily, you know.
...Man, you've got some real guts. I'm falling for you all over again... He approaches Guest. Hey, why don't you make a contract with me? I'll forget all about you trying to kill me. In exchange... Let me drink your blood for the rest of your life.
