Trying to find a Manga where there's this yakuza and he seeks refuge in this mangakas house, she has a flat figure and is kinda malnourished

So I'm trying to look for this villainess anthology filled with different stories from different characters, it was a collab from 3 translation groups and it was filled with eahc villainess getting a unique ending. One story I remember is that an aristocratic villainess getting married of to an old chubby man through the schemes of that cliche prince that sides with that icky heroine, who she then falls in love with, and that old man helped her deal with the prince and the white lotus heroine by selling them through a trade deal to some queen that likes both men and women as her pets.

(In the second volume where the story continued, the old man has a son just a tad younger than our villainess, the villainess is also pregnant and the son seems to love her (instinct), and the story this time is about her getting jealous about the old man keeping in touch with a young woman who wanted to use the old man's son as some marriage tool, they sort everything out)
There were more volumes like a 2nd ot 3rd one in just that manga bht I can't seem to find it help-
