Thanks for going the extra mile, at least we have a explanation to why she was in that state, and it fucking sucks more than the ending, brainwash ended up in killing her because she fell in love, the head miko in the end is the real villain, almost at the same level as all the family of the MC.
MC that was really the incarnation of bad luck, the only good person in his family in centuries and got screwed up by his ancestors to ge all the revenge and bad karma they made, and then got the worse girlfriend between all the girls in the story.
I forgot in my previous post, author even screwed up glasses girl, simply not made her return in the last chapter, forgotten from her maker.
