Which genre do you like the least?

Personally, I'm not really into doujinshi. I don't know if it's just me, but stories about characters who don't stand a chance together, like Todoroki x Deku in MHA or Kageyama x Hinata in Haikyuu, just don't click for me. Not just anime characters but also celebrities and characters from manhwas (such as omniscient readers viewpoint). It's like kind of weird, Like shipping them feels a bit off for me.
