Look, I have my sympathy for Helga because she has to face the shittiest parents, her only caretaker/nanny passed away, & the fact that she's going to be replaced by Helianne.
However, she always harboring copious amounts of hatred. Especially, to her parents and Helianne. I can understand if it's hatred towards her "parents" because they were the ones who are responsible for the shitty things that Helga has to face.
But for Helianne, this is a bit difficult. For now, Helianne seems to be the innocent one here. But Helga saw her as just as guilty for all her problems.
