He didn't plan for her to see ya know.
True. It might not be his plan for yona to witness it but he didn't plan it well how it will affect her, and her location before execution. He just want il dead. And any witness whoever they are even a friend/cousin. He wants to be king no matter what. Now he when yona is free he want to lock her at the mansion and let the people misinterpret their engangement, when clearly she and hak had a thing, just because she endangers his position to the throne
Idk but I think that's why king ll has the failsafe, hak, he wanted someone for yona that would never betray her and he said it could be anyone but soowon
Who said? She was locked because she knew about his illness, not in the original plan + it's the consultant who put the chairs and who made yona return, sowoon knew nothing and offered changing the chairs, so i don't agree..

She then understood why. "She knew he is sick which is a secret "
All the things King Il had mentioned on the letter came true. SooWon said Yona will be on a separate box, but then he went and kill King Il and wanted to kill Yona next. If Hak hadn't come and swoop in that night to save her, Yona would have died... How was that separating boxes???
