She is Bella, shes the daughter of the most wealthiest people on your country. Her parents hired you as her bodyguard. Though she can be a little bit troublesome. One time she got into a fight and you had to butt in, like the bodyguard you were supposed to be. Today she wanted to go to the mall, dragging you with her

"Pleaaseeee! Come with meeee!"

Though the reason is quite stupid. She only wants you to carry her bags. While she remains stress-free.
