i literally read this so so long ago but the story follows this highschool boy whos sister is sick(? idek he might not have had a sister) and he gets stuck in a timeloop of the day she has some big medical event and the only way to move onto the next day (which was then also a timeloop) he would have to kill someone and there was this detective who caught on and he killed him (the detective) for some reason,,, maybe details are wrong! sorry! but thats the best i can remember
