Centeral Characters: Arachne
Anything else: Mild spoilers for volume nine, I believe.
If there was something that Arachne knew she should get used to, it was having things she wanted but would never be able to obtain. Despite the fact that she knew that she should get used to it, she never could. She had been dealing with it since childhood, not only because of her kingdom but because of her first love, Kai, who never felt the same.
Which was why, every time she saw Kira, so obviously engrossed in thoughts of another woman, her heart felt like it would explode, and she couldn’t understand why she couldn’t get over it.
