After being introduced to his new client, Alex spent the majority of his day keeping a close eye on the girl he was charged with protecting. One thing became abundantly clear to him the more he watched Mimi.
She was everything his mother had said she was. Mimi was a kind girl who was not only a bit immature for her age, but incredibly naïve. She seemed to have no experience whatsoever with the opposite sex, except perhaps interacting with her father. This was made obvious by the way she blushed and became timid every time Alex was in her vicinity.
But there was something else that became clear to Alex the more he watched over Mimi. The girl was isolated from the rest of her idol group. This was not something that was immediately obvious to most people.
