this manga was really refreshing, its been so long since ive last read an actual manga from my Wish List.. and i gotta say i have no regrets. it had good timing, the art was really cute, the characters had amazing development. the character though a bit weak was not annoying to me maybe because she reminds me of myself a little too much it hurts. unrequinted love.. that was the story of my highschool life smile and i look fondly at it because no other boy left such an impression so im waiting for someone who will leave a mark xD anyways back to the subject, i liked how it ended.. because im a happy ever after kind of person and it just made me sigh.. it was just so lovely and you just cant help but like it! really! i mean who would not like this? and also the length! the length was just perfect but sometimes the fainting episodes were just confusing.. i mean which parts were the memories, which the actual happening at the moment? but i sorta got it smile

I loved it. It was executed perfectly and was a dream come true. It had a nice moral, good ending, character growth, likable art, and a thought provoking plot. What more could anyone want besides more.

The story is so beautiful smile I just love it biggrin It is well developed biggrin I dont like those 1-volume mangas, because I believe no good story can be in one volume. I was so wrong. This one is very good, the art is beautiful. I just hope there will be a sequel T_T I want to see more romance.

I must say that this is one beautifully executed story and the art really suits it well setting the mood perfectly. The ending manages to have the same impact as a tragic one despite being happy, something that's very rare. Usually these types of happy endings feel like a cop-out leaving an empty aftertaste, but not this one. It really is the perfect ending for a story with a semi-tragic tone.

My only criticism, and this is a matter of personal taste I guess, is that the story is a bit disjointed and at times I was a bit confused as to what actually happened in the past and what she changed. I mean, it is mostly clear on the big points but some details were ambiguous though considering that the author had to show both without being too obvious about it, he/she did a good job. Then again, this is just my personal taste and why I took off a point, but I rarely give such high ratings.

This manga is very beautiful. I just started reading it from my "jumble manga folder" on a whim, and boy was I surprised? This is some deep poo, man!

What would you do if you could relive certain parts of your childhood, would you act differently or just enjoy reminiscing? This manga depicts how easily children can be destroyed for life, just because of bullying, and how their personality will change drastically accordingly. But the manga goes much deeper than that, when it takes up topics about death (and the feelings of the ones left behind) and siblings relationships from a child's and a grown-up's point of view at the same time.

I enjoyed it very much, and now I actually also want to travel back to when I was a kid, to change how I reacted to so many things. Aw... Damn, WHY CAN'T I?


Egoamote, I think the reason why they didn't choose the ending you depict is because that would reduce the audience. It is just my perception that quite some people may drop reading mangas if they are somewhat tragic.

Heptagon is a great story that immediately grabs the reader's attention. The quick pace and short length combine to make it flow seamlessly while also trimming off the excess fat (no repetition, silly gimmicks, etc.). It is also very easy to relate to because it deals with family matters, relationships, and the past regrets that one wishes to change. I highly recommend Heptagon to anyone looking for a good read.

honestly, i was really surprise with this manga. the story is so meaningful and has a lot of depth. i have to say that this is one of those manga (which come far in between) that you will learn so much about. i really 100% recommend it.

This is the kind of manga that gets better, the more you reread it. Like wintermelon mentioned, I think the quote, "Don't think that the crying one is always right!" holds true really well and I keep rereading this manga because I'm occasionally reminded this quote whenever I read other manga with the similar situation.

Spoiler (highlight to view)
Not sure if this even is a spoiler, but just in case.
At my first read, the whole time travel dynamic executed in this manga bothered me. Most stories I've read thus far that dealt with time travel and changing the past, the conclusion tends to be that nothing gets changed or that something goes horribly wrong and then undo everything that was changed and the protagonist learns that it's best to not change the past and face their present and look to the future. However this story does change the past and for the better rather than for the worst. Nana manages to regain her old self and she prevents Hiraoka from being killed.

I was hoping that Nana going back to the past was more of a flashback instead of something supernatural like time travel and that her situation didn't change after waking up from the past (i.e. Hiraoka remained dead) because the fact that the miracle did happen undermines her own personal growth as she regains her true self. The situation would still be the same in the end because Nana herself thought it was just a dream, but she wouldn' t meet Hiraoka in the end because he did die and he can't come back to life. I just think that it's more natural that way and more realistic.

Well I'm just asking for too much and I like Nana and Hiraoka, so I'm glad she saved him and they meet again.

With that being said, this story is more about the journey rather than the ending.
