I think you meant Yu-Hon. Yon-hi is Soowon's mom.
Sorry you are right. With all the similar names it is confusing especially since I am American and don’t understand the different gender distinction in the names depending on the countries.
Yon-Hi does look a lot like Hak. . . I wonder could Hak be the child of Yon-Hi and one of his concubines? All we know is Hak is an orphan and was adopted by his “Grandpa.” Hak is also a few years (at least 1) older than Soo Won and Yona.
