The Tale of A Villainess
Considering Madam Yuan and Xi Ning would accompany the Master, I have no need to be present.
The day before the festival, however, Madam Yuan's left eye became so swollen, it looks like a bee stung her. She cry, only to realize crying worsens her condition. It was not pretty.
To my surprise, nothing occurs to Xi Ning. Not that I am wishing so, but in my book, the day before the Mid-Autumn festival is when Xi Ning accidentally drowns.
Following that, someone from the 21st century would transmigrate into her body. None of that is happening, apart from Madam Yuan's swollen eye.
