The music of change. Or was it? As he studied Jingzhao's response, Tailor-Xinzi couldn't help but wonder if the newly crowned empress' need to change stemmed from self-introspection, or simply arose in response to his indifferent treatment. The answer mattered a lot. If Jingzhao merely wanted to become a woman that appealed to Xinzi's tastes, then her motivations, efforts, actions and reactions would forever be glued to what she perceived as Xinzi's "requirements."
There was also a scenario where, after getting used to Xinzi's pampering, Jingzhao would revert to her old ways. And if his will forever directed all of her behavioral or mental shifts, then at best, Jingzhao would go from slave to servant — never more.
Then again, for her, that was quite the upgrade.
