Book Ideas

I was wondering what everyone's favorite ideas for books were and favorite names for characters and why. I'm writing a horror/Romance/mystery crime manga and I wanted to get others opinions on things, like what they want to read about happening in a book or anything like that. I want this to be a manga that everyone can get into. I can't go into much detail about it due to someone being able to steal the idea. Please let me know and don't be shy. I'm open to any ideas.
