Sima 

Sima is a great friend. She is a badass. she doesn't take other people's shit. At first, she can seem a bit intimidating but if you manage to see past that and become her friend she will protect you. She is athletic and has a reputation for beating up boys from her neighborhood. She has a dark sense of humor. She is a straight-A student. She loves blood. She is gorgeous but doesn't always feel like it. She is the friend you go to for relationship advice even though she hasn't been in a relationship. She has most likely stalked you. She loves the dark web and scamming scammers and loves hacking.

So basically she is a great friend but can be scary. She is smart and beutifull.

Sima is the type of friend i want.
