Hiromi Jounouchi didn't particularly despise Qingdai. Although she had provoked her several times and seemed eager to interfere between Chen Yu and herself, Hiromi found it hard to genuinely dislike Qingdai, but she simply didn't like her.
As for the other soul inside Qingdai, although Hiromi felt some sympathy for its plight, she similarly didn't like this individual and couldn't quite say she hated them either.
But now, faced with a dying Qingdai pleading for her help, Hiromi hesitated before deciding she didn't want to lend a hand or save her.
This certainly wasn't because Hiromi wanted to stand by and watch someone die, but because she felt there were doubts surrounding the whole situation, and that things weren't as simple as they appeared to be.
