Sun Yung

44 years old and Ryo’s mother. She is a highly skilled brain surgeon and the “breadwinner” of the family. She is happily married to her husband, Dan Yung. Sun is sophisticated and detests any foul language. She cares greatly about what others think of her, and does her best to maintain composure. But when things don’t go the way she planned them, she loses herself and her values completely.
