No the sister with the red hair with the useless flower petal powers made a wish that they all lose their powers and the wish became real

But why would that curse even work when her power is just making flower petal

Her power is probably the power of greed or something. She wanted to be the most beautiful and ladylike so she got flowers and now, she wants everyone but her to fail so she looks amazing by comparison.

Honestly, i doubt it is anything complex, I just hope we get an actual explanation for because all of their powers are very cut and dry; FL's just makes the people around her, lives significantly easier
And I have no recollection on what the sons and the youngest powers are

Swordsmanship and I think intellect (he was doing admin). I think it’s possible to be complex. FMC has “good luck” as her power so it absolutely can be something vague and complex. I just don’t think this author fleshes out the characters and bg lore enough

Admittedly, writing around the power "good luck" is super hard, because it can become very unclear where the luck had a hand in which event
For example, the new family finding the pink diamond, because it looked like it was an eventuality if they just continued to dig
But you can also tell that luck came into play with the new brother meeting with the head of the place he just failed to get into

Bad luck is easier to tell because everything can just suddenly go to shit

Yeah that’s why I think the bitchy sister has greed rather than bad luck. Greed wouldn’t show up when she has everything. It would only show up when someone else is better than her and she feels like they are doing better. Her brothers only lost their powers after they called her useless. She wished for her older sister to lose her power. It makes sense in my mind that that’s what her power would be. Greed or envy.
