@Rayster Of course only villainess would behave like that. True heroine would either say some empty flatteries or give some loose change to a kid; just enough to get seen as kind, but not too much as to not touch funds for expensive dresses and accessories.
I'm betting on the Black Knight being her fiance in past life. We just need to see if he has scar under his helmet. If he is who I think he is, then perhaps the assassination plot wasn't really started by her adoptive father.
