I've said it before and, sigh, will probably have to say it again: This is really crap characterization. When Shou was first courting her she was totally capable of fending him off, often pretty violently. So the only reason for her to be all passive with this creep is because gotta have angsty plot--it doesn't fit her personality at all. She ought to have nailed him in the groin. Since the angsty plot is crap too, we have two layers of stupid--stupid bad characterization in the service of stupid bad plot. Gah.
