You made it seem she had no remorse towards him whenever he took her stead. Do you even know what her father was making her do? He's encouraged her to kill by holding Chulsoo over her head to do his bidding. She just can't bring herself to do that, and in turn he beats him how is that HER FAULT? Chulsoo is blackmail material and it's pretty clear most of how she's grown today was for his sake...
Chulsoo sacrificed so much for Daejong i feel so bad for him ( T_T)\(^-^ )
