This is the weakest series compare to any other series I've read from the author. The adults here are only to make touching story between the twin. Teacher, parents, they failed as adults. It's still a good story but not one you would expect from Sahara Mizu/Keita/Yumeka Sumomo.
The start and middle was interesting enough to hold my interest but it wasn't anything too exciting to read however as I reached the last chapter or two I actually shed a few tears and I found the nice brotherly relationship just adorable (I was actually wondering if this was shounen ai at the start but its more family love than incest).
Spoiler (mouse over to view)
The ending just practically made me swoon, I loved it and it just seemed like such a lucky coincidence that the lady would find him and give him the bell yet it seemed designated by fate that he'd regain his memories through the sound of their connection.
I found it very sweet and heart warming and how I wish my brother would do that for me....
Such a touching story! 
I'm touched! Very great! So sweet! can not be described with words! ♥ Definitely THE BEST!!! VERY WORTH! No disappointed at all!
But i quite hate their parents.

Especially the mother! How can he forgot her own child??!! And both the parent let their 7 years old son live alone. THAT'S INSANE!!!
But i still love this manga! Forget the parents, Love the Twins! ♥ 
Cute story, but I really want to beat up their parents D:

What the heck kinda parent would leave their 7 year old son by himself at such a hard moment of their life -_- letting him believe his brother is dead and then lying to their other son about being an only child wtf? just stick the crazy lady in a hospital and take better care of the kids o:< Instead of such bad parents the author should have made them orphans or something, that would have made more sense with that kind of plot, plus they made me mad.

i don't see what the fuss is about... this series has a high rating but doesn't deserve it in my opinion. i can't relate to the story at all also don't like the art. Story is a bit weird.. doesn't mesh with normal psychological (or even abnormal) human behaviour patters, maybe if the family of the twins had more story time and if we saw what the parents has gone through all the way.. but its just impossible to get their feelings in two pages at all. if you have never read a book on psychology you may find this entertaining but i think you'll feel something is missing in the story anyway.
This manga is really sweet. Its just the right lenght for the story, the art is nice, and the brothers are adorable. The promise to make Sakuya smile 100 times is nicely done, and the ending is happy. Its not the best manga ever, but its worth the read.
From the first chapter the plot seems very interesting. Mysterious but also quite comical. Another great work from Yumeka.
Looking forward to more!!
