I think he knew that his asshole like bro would show up there. Maybe he wanted to know if his sister could use the holy stone? Or maybe he only wanted to know if she would die by the hands of the black haired dude or not.... I think he sees the princess as an interesting 'object' and wants to play around to kill some time and have fun?
If it's true then, I don't want him to be the ML （￣へ￣）
Yeah. Right now I'm wishing the OG ML or Dane were somehow made choices for our FL's ML but that's highly unlikely.
Wait! wait! wait! Did he send her there even while knowing that she might be killed??? Or was it a total coincidence that they met in the garden??? I'M CONFUSED!!!
