Kammiya:
Thank you. I was just wondering about the relationship between Hui Ju's parents. So it seems that her mom remarried after leaving her father, and her mom's new husband also had a daughter from a previous marriage.
You are welcome. From what I understood, after her parent's divorced, her father asked her to stay with her mother because she wanted to become an anchor. But I did not get why she had to pretend to be mute. And why her sister fled the marriage. Of course, she did not want to marry Sa Eon, but there might be another reason. If there is no other reason. That would mean that In A is a spoiled brat
