It is true love.. yeah right This was so satisfying when I think of the Japanese story trope This comes to mind: https://mydramalist.com/1354-boku-wa-imouto-ni-koi-wo-suru Since I am a Matsumoto Jun fan I got to find out about it. Not interested in watching it even if I am paid. The trauma from School Days was bad enough. I learnt that you need to do your research before consuming Japanese media or you will see something you cannot unsee
I have learnt of this the hard way, there are so many things that i wish i never see in the first place. Somehow i feel that i lost something over the years from this most european royal family were a fan of wincest too, just take a look at their family lineage/history
