As a deity of the earth above, she was not very fond of the gloomy Underworld. However, unlike before, there was no longer a mother forcibly demanding that she must stay in the narrow valley.
She could freely reside in this vast land, even if it was still a bit monotonous now. Although reason told Persephone that it was Demeter's decision to protect her, she could understand her mother's actions. However, to make a girl filled with curiosity about everything live in isolation and remain in a secluded valley for a century was torture in itself.
Besides, in her view, perhaps her own mother had better ways to protect her instead of hiding in a corner deceiving herself.
Therefore, Persephone resented Zeus, who had led to all this, but she was not particularly close to the mother she had only met a few times. She felt like she was just a 'seed,' still buried between crevices and rubble, just like her godhood.
