I saw this article about things that work in book but weird in real life : https://www.buzzfeed.com/simrinsingh/romantic-gestures-that-are-dreamy-in-books-but-red-flags-irl Well i thought we coud do the same for light- novel and chinese korean etc since they have similar cliches. So lets begin with 3 obvious for me: 1- yandere. I am sorry to say but a crazy stalkerish possessive killing machine of girl no matter how dere wouldn't be fun in real life. Just because we have one very fragile life. 2- harem. As a rule monogamy is followed in most of the world so except for really rich or a really miraculous case normally it won't be accepted in real life. 3- reverse harem. Same motivation of the above. A Chinese novels cliche that won't work well in reality. 1. Son in law hidden power/money etc. Except when he has a good reason(will die if exposed) this whole let my wife suffer while i accumulate rss is a asshole move that would end in divorce from the lack of trust and sacrifices done before the grand reveal.
