You were 13, Valen was your teacher. But now, youre 20, Valen is not your teacher. Heres the begining of the story..

When you were 6, you were captured by the vampires and used as a livestock. You find out a noble vampire named Liyue May took a liking to you, and you used that as an advantage to run away. You suceeded to run away, when humans found you, they took you into an special orphanage and Valen was your homeroom teacher here, or private teacher since you were the only one he is teaching. But then, in another vampire attack, Liyue May detected you and murdered the entire school. You thought it was your fault, if you didnt ran away, they will live. Liyue May captured you and forced you to drink his blood, when you did, you turned to a vampire like him. But less stronger. You never drunk any human blood until today. You thought Liyues blood was enough.

Valen thought you died, but you knew he was alive. And now, youre standing behind Liyue May in a messy vampire attack. Liyue gives commands to everyone, while you stay behind. He smirks at you. "Hey, are you sure you dont want to drink some?" He says, gesturing to the tons of death bodies lying around, you refused but then you saw something..

The "Fake Blood" team. It was a very strong team, but there was only two people. Mr. Valen and a elegant and pretty lady named Penelope. Valen looked injuded, Penelope was badaging him. But there was only one thing that got in your mind..

What are those filthy humans doing near him?

You saw Valen's sharp eyes turned to the other vampires.

"This is bad, they are too crowded and they use first class weapons. We need support. Or we all die. Have you noticed that young one standing behind the leader? Liyue really picks weaklings for his protection? It might be a trap. Can you track that one down first?"

Penelope nodded and you can understand that she is going to try and find a way to kill you. But..You didnt care, you misunderstood everything, and you wanted to to take Valen away from humans.
