Honestly, I have no clue. 'Paramour manga' and 'baka' seem quite disconnected and could be part of a very specific or unique context that's not common knowledge.
There are several options. Some people find success on Webtoons or Mangapark. But keep in mind that the availability might vary depending on licensing and region.
Well, sometimes you can find them on specific manga-sharing platforms, but make sure they have the proper authorization. Another option could be checking with manga enthusiast groups on social media, but again, be cautious of the legality and authenticity of the sources provided.
