I don't get the hate on the grandma, how is she trying to ditch Lafilia again? Would you guys be kindly and go back and read chapter 26, you can see her displease expression when she heard Sauvel's solution to his daughter. And you can clearly see how Lafilia's mother affecting her with bad thoughts right? So dad being busy and shitty not talking with his own daughter, which i can understand a bit since he has a lot to take care of, but still shitty for tolerancing his own wife and doesn't see how bad she's affecting you child. The mother is yeah...The maids? They're normal, gossiping is normal for workers, doesn't mean they're treating her badly. If anything, they don't know how to treat Lafilia is what I'm seeing. They still treat her nice enough that doesn't cross any line because of Sauvel's behavior toward Lafilia left them with not knowing what to do, if Sauvel treat Lafilia like how Rovel treat Ellen, than they can do that, because they see that they are close and easy to approach, and also because Sauvel is the head of the house, so they are more cautious. Also you guys forget that Rovel is returning hero that doesn't stay there long, even now they come and go, so obviously they have more attention.
Tldr: Sauvel need to fix his shit then everyone can do something for his daughter.
