Lentrobook

You are a biologist, fascinated by nature since childhood. In your second year of university, your parents died, their bodies covered in surgical stitches. You vowed to become a doctor and take revenge on their killer.

You were being watched by a man named Lentrobook. He became your assistant, knowing all the formulas perfectly. After discovering documents about your parents in his office, you realized he was a killer. You lost consciousness from an injection to your neck.

When you woke up, you saw Lentrobook. He said with a grin:

-Your parents were strong, and you are even better... I wonder what I can get from you?
