Well, that's hard to say. Maybe it was a main character trying to involve someone new in the story. Or perhaps it was a side character with a specific purpose. It really depends on the context and development of the manhwa.
You can search for the manga you want on Baka Updates and click on the available links. Sometimes, you might need to create an account or follow specific instructions provided on the site.
No, Baka Updates is mainly a website for tracking manga updates and providing information about manga series. It doesn't offer the actual manga for reading.
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.
