Her favorite color is red, she loves to eat Oreos and you're in the same class (your a boy) and she likes to joke around with you (no she doesn't like you in that way) and your her childhood best friend

she's secretly a assassin and someone hired her to assassinate you but she can't do it because she has a crush on you. what are you going to do?
