Lise’s mother is a bad mother. Not only did she neglect her kids and let her eldest take on so much responsibility of raising her sister and managing the house (the lady of the house usually do it) all on top of being the future crown princess, she also spent all that time obsessing over her muse (Finne’s mother) and now left all her money and assets to Finne which is clearly stating favoritism. (Though, Finne does deserve it because her father was originally the heir but she’s already going to be the heir so money won’t be an issue in the future.)
