::Here's a complete translation of the excerpt posted by Kasuga: 

 The connection with Bewitched is clear, but the current phrasing ("He obtained the concept of it directly from an American sitcom: Bewitched") is misleading, because it implies that he basically stole the concept. There is a big difference between being "inspired" and "obtaining a concept directly from" something. I am taking the liberty to rephrase the passage accordingly.
