Why did the characters change in personality? According to the first chapter, the white haired sister seems to genuinely love her family (minus Pleta), and genuinely thought that Pleta was a blight that had finally revealed its true colors. Now, she's manipulative and is basically Being set up to be the main villain of the story.
Also, why the heck is the Duke there? I mean, we're not going to question about why he's suddenly always popping up? And the cliché "I can't read her thoughts, which means that she's special, which means that I suddenly love her with all my heart!", really???? Why the heck was there a sudden drop for a romantic route?! This story does not need romance!
This manga was so nice and interesting in the first chapter, but then it felt like everything was forced to shift to the usual cliché romance/I know about the future/the one I thought I can trust is actually my enemy/I must remedy the past/OMG, random plot twist that everybody pretty much knew would happen story.
I am so disappointed...
