Thanks for the translation!
I am maybe cruel, but at this point, I wish for the sudden death of the emperor. So this way the wedding is cancelled and Ye Hwa will be in safe(r).
And second, the princess not want to get married to a 50 years old guy, with a harem, but she think Ye Hwa would want? Why would she? For me, the princess is a spoiled brat, and I really want her to be in Ye Hwa place, when her father wants to sell her off to a brothel. Just to get a little taste of the world. (To be more specific, I don't want her to be selled, just the know, that it could happen)
