You got one thing wrong here the doctor isn't her boyfriend her actual boyfriend got killed but this guy alzo loved her and so did she
the doctor maybe related to her deceased bf maybe his brother
but then how did he know about everything that happened? and how come she didn't recognize him?
He did say something about hypnotising the woman.. At first i also think that the doctor was the boyf but it doesn't make sense so i think the doctor was someone who just have a complicated feeling for naomi ╮(￣▽￣)╭ but one think i don't know.. The assistant detective relation with doctor(╯°Д °)╯╧╧
that was so beautiful story and so the killer was her friends and the murdered victim is Naomi's boyfriend whose the doctor in disguise and was all planned out and in the end JUSTICE IS SERVED
