this is a science fiction manga, but it still making us think that wishing this kind of thing can happen to us, change our past because we're messed up now.

when we look very closely, in a first place, Ichijou was a selfish person. he's afraid about all the things he had done in the future because he'll get killed. and his priority is just to do things in a right way in order to not get killed.

but along the way, he know that, if not for the power that bring him to his past, he would've never feel all of this experience he never had in his highschool live. everyone around him change, and he's changing too, and that's what matter.

but no matter he can change it, doesnt mean everything will change, indeed there will be consequences, but the feeling of joy, redemption, and happiness that he''ll never had before will bring so much better for him and everyone around him, Ichijou would never hold any regret.

i'd really enjoy this manga. it doesnt difficult to understand because all the narration inside Ichijou's head will sort things out without making us the reader thinking too hard. and it's short, the story didnt waste too much chapter to get things straight, but it's still pretty easy to understand with just 22 chapters.

10/10 would reccomend to friends and family.
