Hey, I remember reading a horror/tragedy/psychological-ish manga a while ago and forgot the title. In the manga, the MC and a group of girls find out about a online site with videos that predicts their deaths and the girls completely snap over it. I remember there was a part where the MC had to choose who to save, and a girl that he liked started to come onto him to try and be saved. I also remember the manga being unfinished, and having a really cute art style.
If anyone knows the name it'd be really helpful, thanks.
