Funny female leads, isekai (mostly)

MC gets murdered in her previous life n gets isekaid to another world as a newborn baby.
At the beginning I found the comic funny n intresting. As you with time get to know all the characters and understanding them better. However later on I found myself disliking MC more n more. Its like she never lived a previous life, acts way to immature n naive, which destroys the whole reason with isekai.

Hardworking and funny MC.
In her previous life she was poor, always had to work hard and did not get any acknowledge from her efforts. She gets reincarnated into a novel and into a rich noble household.
