Based on spoilers I read a while back, I believed Ido sent his brother to the house to expose to the brother information of brother's corruption or something of the sort. Ido did not expect Sejin to leave his room.
But Sejin did leave the room thinking it was Ido. Then Sejin misunderstood because of the brother's jeering remarks ┗( T﹏T )┛
Wait so did Ido really send Ijung to his house to rape Sejin or what?
