I would like for them to become real couple though even their both crazy

I really don't...
Because it is clear that the author is being manipulated by the kidnapper :(
And this means that one day if the Kidnapper actually gets tired of the author, he'll literally kick the author out.. And since the author doesn't have anywhere else to go, he'll become really depressed...
I don't wish that kind of life even on my enemies :(
