This is not just a regular step-sibling relationship. It's deeper than that. *Note* This whole section is going to contain a lot of spoilers

I believe this mangaka is pretty smart in the way they set up the story actually. It's one of those kinds where you have to piece together all the information it gives you by yourself. The conclusion I came up with is pretty dark though, not sure whether some readers are going to like it -----> Shiori and Miyumu are real siblings. The parents broke up when they were children and then later got back together.


- Miyumu's hair color is said to be the same as her fathers' "rare patchy brown".
- In the flashback where the boy said his mother gets her picture every month and that she cries and yells. If the woman was a stranger why would Shiori's dad send the picture? If Shiori was the child of another woman (half siblings) the dad would not send the picture either.
- The parents, according to Shiori, got married straight after they met. Sounds like a patched up marriage.
- At the end Miyumu asks her if she can really say "it's okay" even if they are brother and sister. He knows.
- When he asks her if she remembers the past and she said she cannot, he said it was probably better (she won't piece what he said in the past together with the truth) and that he will forget along with her (forget that they are siblings).

The authors thrown too many hints in there, and I can't think of any other explanation for it. The mothers sadness over losing Shiori might also be why he acts so psycho. He was probably ignored by his mother while she was in depression, and he became jealous and felt un-loved.

'kay, this is disappointing. it's just your average step-sibling love. i don't know, only 2 chapters are out but seems to be. the bro is a total @ss and the lil' sister is an optimistic air-head who will probably end up being a masochist.

Beautiful drawing style & common storyline.

First - I often focus especially on the artists style and this time I was satisfied, because the (slender) character design was definitely to my liking. The same goes for the stylish elements (e.g. photographic backgrounds and modern clothing styles) and rather edgy outlinings. So, just because of this my rating already goes up. But ...

The storyline was rather generic and weak. The whole step-siblings being in love scenario is well-known in the Shoujo genre and even the sadistic personality, which I usually like for one of main characters, couldn't add something special in this case. The ending was also somewhat lacking, because I would have wished for a better conclusion of the set up. If not for the happenings of the past, then at least for the future situation of the characters (& their family).

So, if you are into modern artworks and if you can take some disatvantages in the story's area, then this can be interesting for a short read.

The story ends pretty quick. There are some stuffs that are left unexplained, but from the hints given in this story, I think I can see the way the story goes.

Too bad that the character development is not that good. For example, Shiory seems to be girl with girlish fantasy, sometimes she's reliable than that, but sometimes she's just a crybaby. And at another time, she can be aggressive. Miyumu, too. He is a sadist, a bit lonely, but sometimes

Everything is developing too fast. There must be a better way to reveal and explain about the plot itself, rather just blurt it out in a "normal" panel.
Spoiler (mouse over to view)
Just like in the last chapter when Miyumu told her about "the friend of a girl who used to walk with the dog", Shiori just answered straightly "that girl was me!" And................ what a downer.
Another example is when Doremi seems to remember Miyumi from somewhere. At first I think "Oh, is this leading to the deep-secret part?" But the way she just rambles it normally is...... a total downer. Again.

Nah, I really can't say if it's good or not. Just average. The way the story is portrays in each panels is still weak, in my opinion.
