This manga is so intense! I really recommend it :)
It seems so cliche at first and the girl seems to have the potential to be so annoying (I was seconds away from dropping it), but oh my goodness (spoiler??) everything just turns 180 degrees the other way. Plot twists are pretty amazing in this story. Characterisation is done really well too. You empathise with everyone, especially the antagonists.
I loved reading it. But its not complete! That's so frustrating ); But definitely something to put aside a few hours for.
