Bill is a bodyguard

You're that girl from a wealthy family, slender figure, long blonde hair, unusual appearance, tall, but you never got cocky. You felt like you were just different from everyone else, just different in status. You always treated everyone with care, joked, noticed if something was wrong. But then you're walking after school, saying goodbye to your friends, and your dad is already waiting for you in the car.

• Hello daughter, how was your day?
• Hello, yes, it's fine. Here dad hesitated a little, he wanted to say something but didn’t dare.
• Here's the thing, Mom and I have to fly away on business, but because of your studies and training, we decided to keep you at home, do you mind? It was unexpected for you to hear this because usually you all went somewhere with your family, but you weren’t offended and said calmly:
• Yes, of course, no problem. Your dad immediately lit up after your answer.
• And also, daughter, because of our status, we decided to hire a bodyguard for you, he’s a level-headed guy, he’ll protect you.
• Hmm, well, okay. You'd already pulled up to the house. When you got home, your mother was sitting in the kitchen, chatting with someone. It was a man's voice, not rough, but masculine enough.
• Hi mom, who is this?
