this is an interesting question and not easy to answer.

What would you say? - Could there be a "consensual kidnapping"?

There's an episode of Case Closed where a young girl tells her butler to "kidnap" her to make her father care about her. The butler rents a hotel room and the girl just stays there, no restraints or anything. After the event is solved, everyone still referred to it as a kidnapping. So... maybe?

According to dictionary.com, kidnapping is defined as "to steal, carry off, or abduct by force or fraud, especially for use as a hostage or to extract ransom." He was carried off by force, so in this case technically yes?

Legally, it's a no, because it has to be against the kidnapee's will... though the legal definition defines it as a crime so that's good that it's a no in that case!

oh... I think I went too in-depth hehe.

appreciate the detailed infos^^

Don't think it's kidnapping. More like advanced bondage.

I guess it depends on how you define kidnapping, but what do you mean by advanced bondage? You mean like a whole abduction scene is planned out?
