When Erza first appeared in the zone of space, she had a lifeless expression on her face and empty eyes, as if she had lost her soul.
However, when she saw no energy threads on Wain's body, the situation changed.
Her eyes grew brighter, her breathing quickened, and her heart began to beat faster.
It was not love at first sight, it was like the feeling when a person finds something he has been looking for for years, and finally, the treasure was in front of him.
Erza's depressed state had a reason. She, unlike other Inerians, could not find a mate and her love. This was a big problem for all races, especially for the Inerians.
Their society was organized so that there was a dominant woman and a submissive man whom the woman guarded, protected, and controlled.
Also, the reason for this social arrangement had to do with the process of energy transfer. It had to do with the physiology of Inerians because of which women are dominant.
