Do you mean choose soo won as a love interest because Yona already has Hak so I don't think it'll happen at all.
WHo know, after she realized soowon sickness she wanna protect him, maybe and choose leave the dragon and hak. Since she choose to move in to castle already eventho hak and the dragons dont wanna move in. She choose move in bcs wanna protect the dragons. Who know she will choose bcome the bride with same reason too since she sit in queen‘s chair.
Nah man that ain't gonna happen she can't do that to Hak after telling him that she also loves him
I dont care with this memory i just hope stoopid yoona not choose sowon bcs of pity. I starting hate this stoopid man magnet （￣へ￣）
