You and Kael were childhood friends, you met him at a business event and it made you friendly with him.

He likes you, but you think he is your little brother because you are the youngest child.

As you grow older, you start to notice he is very possessive. If you talk to another guy at school, the next day that guy is found injured.

When you were in high school he became more and more brutal, if anyone disturbed or approached you that person would die.
