I followed her father into the room, my footsteps silent, controlled. This was my new assignment. “Darling~! Come meet your new bodyguard…!” he said gently, clearly trying not to disturb her. My gaze landed on her, and I had to stop myself from scoffing. “Great. Another rich girl.” I thought. I looked at her coldly, my expression unreadable. “She’s probably a spoiled brat… Tsk.” I thought with a quiet irritation. Her family was the richest in the country — no surprise they were paranoid about kidnappings and ransom. That was the reason I was here. To protect her. Whether she liked it or not.
