At the very first chapters you have to question whether or not you're actually a pedophile for enjoying this manga.
Story-3
The story actually has an interesting take; a good for nothing 25 year old, who travels back in time gets to live out his days as a dirty minded 25 year old in a ten year old's body. I'm sure multiple people would want to travel back in time to redo their lives or to live out simpler days, but this manga isn't a drama it focuses more on the comedy and the innocence that you probably had as a kid, and then twists those innocent situations into straight up ridiculous sexual references. Maybe I have the humor of a dirty minded 25 year old but I did find myself laughing at the unrealistic situations. The story isn't deep, meaningful or meant to move something inside you. The author wrote it for people to have fun reading it, so it's not compelling in anyway.
Art-9
The artwork for this manga was really something. The characters are well drawn, and each chapter was nice to look at. He made the each girl distinguishable in their own right and dang cute.
Character-8
The characters themselves I loved. My favorite characters were, the too innocent for her own good Sayo and the super playful but dumb Manatsu. The MC doesn't go through major changes, he learns a lesson but I believe it's a lesson everyone would learn if they went back in time; to try harder. His feelings never change but the characters around him do. The story might be about a boy name Shouta but he is isn't the best character by far. I guess a harem is really only as good as the girls in it.
Enjoyment-8
I usually read manga on my phone while dropping a deuce and I would look forward to the daily deuce everyday to read this manga. The story made me feel nostalgic and think back to days in elementary school and how naive and innocent I was. The comedy hit a funny bone with me and I found it to be refreshing although I didn't like the ending or the girl he ended up with.
Overall-8
The manga has very strong lolicon themes and I do advise against if you do not have interest in that type of thing, but beyond me not wanting to read this in pubic this manga was a good find. If you're a lolicon, or a dirty minded guy with a childish sense of humor I would say read a few chapters.
