Yue, born as aletia galdea vesperitio avatarl, was the daughter of the rulers of the vampire nation avatarl. At the age of twelve, she awakened the ability to automatically regenerate her. Yue’s attitudes towards shia changed after the reisen labyrinth and she began to love shia as a little sister. It was fine to yue that the two people she loved most also loved each other since. Yue has a friendly relationship with her as she feels sympathy towards her due to yue's past as a princess and queen, and offered her sympathy when she was into an engagement.
Your probably not wrong. Honestly it would be.
