Oh,I see, someone noticed my comment lol. Well,yeah I read some spoilers because I don't understand why the other commenters said that FL was actually the bad one and Ercia was actually the good one. I just gave my opinions that it's not the twins fault why this happened to them now. It's their parents fault and the grandfather as well. The parents and the grandfather were enablers. They let this happen. Considering that the events happened when they were around 7-9 years old. It's totally the parents and the grandfather's fault. Did you really read my nonsense comment? Geez, it's embarrassing..
Oh,okay. So the thing is,Ercia is the real genius and the rightful heir to the Viscountcy. FL wanted love and attention from her family since she felt left behind and cast aside. So,she harmed herself,and she realized that that is effective since her family showed their love and attention to her.The sister sacrificed her position and her life for fl's sake because their family asked her to do it (?). I can say that their family, including the grandfather are enablers. I can feel how painful it was for Ercia to do that decision. She cannot say no at that time since they were just kids,and she will look greedy and disobedient if she refused. Since they were minors at that time,the parents are to blamed. The grandfather knew all along and continued to orchestrate fl's life.
So what happened in their past lives and in this current life is due to deceit. I cannot totally blame FL and I also cannot totally blame Ercia,both of them are partly to be blame and both of them are victims of partial love. If only the love and attention of their parents divided fairly,none of them became greedy. Enabling is not love nor any form of love. It will only make matters worst. Just what happened now,it ruined not just their sisterly love but their lives as well. The grandfather should have told FL a long time ago and did not deceived her any further.
