Is it because she killed too many people or because she fell in love with someone she shouldn't love, so God wants to use her sister to punish her - let her watch the man she loves get married with her favorite sister; let her watch her favorite sister be instigated by the man she loves and leave her covered in bruises; let her be betrayed without mercy by her most trusted partner.
It was not until the last moment that she understood everything. It turned out that her sister hated her to the core after knowing that they loved the same person - even though she was the sister who loved her the most.
Angels have never heard the demands of mortals, but the devil hidden deep in the heart of man will.
Angels also appeared, allowing her to choose a new life.
