First time writing a review so have mercy on my grammar and such
Story 9 = Kasane from the word itself googling it up (source: wordhippo.com) means : layer, pile, suit since our character is just wearing another persons face. I really like the development of the story showing the early chapters of what her school life have been then leading to her maturity. I gave it a nine because there are chapters that are a bit cliche but overall it was done well.

Art 10 = I dont judge much mangas about art aslong as it doesn't confuse me still the art was beautiful for me especially the volume covers.

Character 7 =good but nothing much was very worth praising here. mc just being amazing, struggles, etc.

Enjoyment 10 = I did enjoy reading this even if there are questions that are boggling me, like: "Why doesn't she just take plastic surgery?", "Does N***'s parent's no longer bother visiting her even after that incident?", "Where are the police". Still I enjoy this manga has brought me suspense and surprises .

Overall 9= It was refreshing manga to read amidst in a pool of isekai I've been reading lately, I would recommend this to readers who like suspense/thriller mangas.
