Nana, an apathetic 24-year-old with nothing much in her life, suffers a car accident and wakes up in her 14-year-old junior high body. As she lives through each day, she starts to remember things she buried deep in her memory, and she can now not remember being involved with her older sister, whom she deeply admires, and her sister's first love, a senior at her school.

I've read it about five times.
It'd be cool if you were able to travel to the past, to your old self. But we can't and this story make you wonder how much you can change in your present. And to rethink about yourself and who did you use to be.
Love the last scene: in the elevator. I didn't get it the first time. Even if there is a love story, there is more about the identity

There's good foreshadowing and character development within this manga. I also enjoyed how everything fits perfectly and has a nice symbolism regarding the heptagon and the number 7. If you speed read it will be confusing, but if you take your time you will understand it. It isn't long, but has enough to give you a nice and sweet story. Recommended

I highly recommend this manga.
It's short and a bit confusing (makes more sense after reading again) but the message is endearing.
It just makes me want to cry. Haha.
It's a good re-read too.

The twists were pretty interesting and so was the "love story". Though, I'd say that Harukana Machi-e was way superior to this, in terms of depth and maturity. Heptagon does hold quite a bit of weight, though.

Maybe what made this manga so good was the cliffhangers lasting months of anticipation. It reminds me of a one shot, 1/6000 Honesty. It is very well made with beautiful artistry and the story is very nice. THe time travel is done exceptionally well and it's very easy to bond with the main character. The ending... I loved the ending. I thought something else was going to happen. OMG... SO GOOD!!!

I just love this manga. It's an interesting supernatural time travel kinda story where the protagonist was given a second chance to redo or find the true reason of why she's gone back to the past and save the guy that she didn't know she was in love with until it was to late. I like the part in the end when they were in an awkward moment in the elevator and the guy suddenly said, "I have your hat.." lolx.

or rather josei.. but y'know

check out harukana machi-e for a seinen take on it sorta =p... i think the seinen one is much more mature and cool
though this series is also very very good

I love this manga. Although it is not fully scanlated, from what I already read, the story was deep, meaningful, and quite interesting. I love how the story shows the evolution of the protagonist. The story tells you how the main character became the way she is and it also shows the process the character undergoes in order to understand herself.

If you like this manga, you might also like Seigi no Mikata by the same mangaka.

Remember that old show they had awhile back about a guy who was able to go back in time and have a redo on everything starting from high school that got cancelled in like, 5 episodes? Heptagon is like that - except this doesn't suck. If you like Josei stories, do yourself a favor and read this.
