@JustA_ @Runs_With_Scissors It's the opposite actually. Iirc, the first sister had the 4th sister's maid killed. She did so to take back the mail that she had kept in a jar (that was broken on purpose by the 4th sister to get that mail).
Apparently 4th sister's lackeys finnaly found the corpse so she thought it was a good thing to slap her elder sister in front of everyone... Obviously next chapter she's gonna get put in her place by the father/grandma pair. I can't wait for the 4th sister to be out of the picture, I just can't stand this character, she's the most stupid of them all, and that's saying a lot...
