I never demanded anything from the dev - and never will, because the dev is free to develop the game as he likes do. It was sorely my impression when I played the game for the first time - up to the point where you got the choice to share the mom to her son - before the rework happened. After the rework it went to the extreme with the netori stuff for my taste. However, I'm not here to argue about a more friendly sharing approach compare to what we got.
I think it was nicely done for a Harem game the son has this obsession with the mom and sister, he has a hot wife and now the 3 belong to the MC, the son is a bit of a nuisance at he moment just like the husband was but that is part of the story How the MC gets his pets.
from my view Laura is Corrupted good, docile but sort of passive, (sure she now thinks that its a good Idea for Master to breed his pets, but she always needs a push), but the daughter in law has much more potential as an active pet. she had an empty life and now she is awaken and looking to the future as a fully loyal pet.
the table scene where she commented that her life used to be empty and now is full, her eagerness need to see the corruption of the new girl by her master.
she just started, but seems like she is more than ready to leave her old life.
