tarareba presents 5 short stories around 5 chapters that always show the protagonist of the story in question regretting something, and then gaining the ability to go back in time because of two girls who have the ability to do this in exchange for the second most important thing for a person I think it's a bit mysterious, and I really wish there were more volumes, in fact I recommend it, I just think it's acceptable because the fact that there's only 1 volume doesn't show much about the two girls, who in this case I believe the biggest one is a master, and the littleone a pupil

Yes, there are some triggers, especially in the last of the 5 stories, so if you are sensitive, don't read it, as there is blood in some parts and other scenes that are not very comfortable.
