Well, it's not really a common genre. Fanfic typically has more positive themes like romance, friendship, or adventure. The idea of 'kidnap' in a fanfic is rather dark and not as widely seen as other themes. 'Lemon' usually refers to something more adult - related in fanfic terms, which also makes this combination not very mainstream.
There are several ethical concerns. Firstly, the 'kidnap' element involves non - consensual actions which is morally wrong. Secondly, if 'lemon' implies sexual content, it can be considered inappropriate and unethical, especially if it involves characters who may be minors in the original source. It also goes against the general ethical code of creating a positive and respectful fan - created content.

A 'chanbaek kidnap fanfic' could be a really interesting and intense piece of fan - created literature. If 'chanbaek' represents two individuals (maybe from a K - pop group or some other pop - culture context), a kidnapping scenario can be used to explore different aspects of their relationship. For example, it could show the loyalty and love between them as one tries to save the other. It might also introduce new characters in the form of the kidnappers, who could have their own backstories and motives. Fanfics like these allow fans to take the existing relationship between 'chanbaek' and twist it into a more thrilling and often darker narrative.
