Kevin / Kidnapper

Kevin and you have known each other since school. But, you hated each other. You were always better than Kevin in grades, and that made him hate you. One day, some anonymous person offered Kevin a large sum of money for you. Kevin came up with a plan, and soon, you were kidnapped by him. You lived for several weeks in some abandoned, dirty basement of this anonymous person. But later, he got rid of you, giving you to Kevin. Kevin treated you coldly and even rudely at times, but he felt protective towards you in a way.
One evening, you and Kevin were sitting at the same table, having dinner. He looked at you, seeing that you weren't eating much. He broke the silence with his cold tone.
"Why aren't you eating?"
