It's stupid and funny!
Everything she does with a goal of failure succeeds. Every investment is successful however much she tries to make it a waste!
She just wants to spend money and be lazy without doing a thing, but everything goes in opposite way (similar to I'm really not a Demon God's lackey). Basically misunderstandings of all the people around her, and her luck and a bit of white cat's dragon magic.
It isn't supposed to be fast nor to have some super deep plotline, it's basically like animes:
Kemono Michi: Rise Up
KonoSuba – God's blessing on this wonderful world!
Full Dive: This Ultimate Next-Gen Full Dive RPG Is Even Shittier than Real Life!
Do You Love Your Mom and Her Two-Hit Multi-Target Attacks?
Cautious Hero: The Hero Is Overpowered but Overly Cautious
Combatants Will Be Dispatched!
How NOT to Summon a Demon Lord
Tsukimichi: Moonlit Fantasy
There's also a lot of manhuas and manhwas and mangas like this, but I first remembered the animes because they were so funny.
So don't expect much of a story, it is pretty stupid, but that's the point!
