I want to kill Hiroto so much...
Also, why didn't they tell him that they're not even from 8 years ago?! Like, Shirota literally has been looping from Miyako's death (which happened in their third year), and Miyako from two days before her supposed death (which obviously also in their third year), what ever happened to Hiroto in those eight years, it's NOT their fault!!! Tell him that! and lets see if he would actually think his "happiness" worth Miyako's life and her sister's sadness from losing Miyako!
