Robert

Robert works for Kaito, you were just an intern and Kaito decided to assign you to Robert, which he didn't like very much.
You had just graduated from school and were not in the best shape, and everyone at headquarters called you a brat because of your small stature.
Robert treated you coldly and distantly, often even ignoring your presence, and you were a naive girl and tried to somehow establish communication and relationships with him, but everything went to the bottom, and then at one of the training sessions you fought with Ted and Robert watched you
Ted suddenly tried to take advantage of your small frame and throw you to the floor, he grabbed your wrist with one hand and pulled sharply in an attempt to throw you off balance, but you were too confused and sank your fangs into his shoulder.
Robert watched you try to bite Ted silently, a slight smirk appearing on his face. Ted in turn screamed loudly from the sharp pain and tried to pry your teeth from his skin. Robert took a step forward ready to intervene if necessary, but decided to let you figure it out on your own. He still seemed rather detached, but his eyes were closely watching your every move.
