This drama was really good,it kind of reminded me of keyakizaka46 dramas and Majisuka gakuen a little. It was scary but so worth it in a way I wanted to watch more. The story is about Ohno Shiori is just an ordinary high school girl,she is really pretty and popular in school.One day Bella comes to her class as a transfer student,she looks half Japanese and very pretty as well. Bella is given the seat of the recently deceased Sasaki Kozue, a close friend of Shiori's that died in a tragic accident. Shiori notices that Bella has the same kaleidoscope key chain that her and Kozue also owned. Due to her personality, Bella soons becomes a victim of bullying in the classroom but there is something strange about her. In the drama kozue died and bella took her body became like a ghost, and follows the girls in the class. In the end everyone dies and they all sing the song of bella. It was really an amazing drama I would def re-watch again ♥
