great story for such a short volume

This book is definitely one of the better reads out there. A tug-your-heartstring, make-you-kind-of-weepy story, but one thing I like about this is it was almost never predictable. (Or it may just be 24 hours of no sleep talking here.) Anyway, I recommend it if you like good shoujo w/ a few cliches. This is definitely not an if-you-have-free-time only manga.

p.s. People who have basic knowledge of Japanese culture (or who have read a lot of manga) would know that in Japan, it is legally okay to marry/date your cousin (even a first degree one). Incest, by definition, is sexual activity between close relatives, which may or may not include first degree cousins (I'll put my money on the "may"). I don't agree w/ the first comment, but even so, by definition, incest would not actually be an appropriate category for this manga, since there is no sexual activity at all in this manga. NONE. NADA. NIL. Capiche?

Unexpected clarity of emotions...

Unexpected clarity of emotions which holds steady throughout the entire story, little to no drama, little to no tantrums, strong and interesting characters throughout the story, tension that tightens repeatedly, unexpected secrets and best of all: the major plotline was kinda predictable yet it unfolded unexpectedly.

...if he weren't that cold towards her.
I found it hard to believe the ending because of Reiji's coldness, or should I say lack of character?
I liked the unexpected twist regarding Rumi-chan (though after sooo many years of reading manga I could kinda sense that).
Overall it was a nice light read. I do recommend it ^^

Rumi was just so supporting and lovable; I wish the heroine ended with her instead. I never read LGTB manga but I would've been fine with this being straight out shoujo ai. Aside from the really nice relationship the girls shared, the story was only filled with typical mean girls and cliches. The male love interest seriously lacked personality he was typical as fuck.

i liked it! but not tooo much. it didn't give this excited feeling i always hope for when i start to read a new manga. well, wasn't expecting much from it anyway, since it was only 4 chapter long.
other than that. i like the characters smile)
i dont really care much about how rumi's lesbian. i loved her character anyway. i kinda look up to her. yea, i'm silly. she kinda reminds me of myself. but not as strong as her. so i really like her.
i really like anna, too, she's really innocent and nice.
reiji was [hot] embarrassed. not as hot as sakisaka's strobe edge's main guy character, but yea. he was nice too biggrin

American definitions do not rule the world. Legally, marrying one's first degree cousin is NOT incest in most other countries (even if it is icky). So stop judging everyone by YOUR standards.

Rumi was too supporting...

I know Rumi is supposed to be a strong character but it's a bit unrealistic that she can be so supporting and understanding. I also hate her disappearance in the last chapter. Where was she?

Better than average one volume shoujo manga which featured characters that had some realism to their feelings and emotions. All the cliches were present: a bishounen lead loved and adored by all who set sights on him, bullying fangirls, and bittersweet feelings that the main female just can't give up no matter how hard she tries, but what made it somewhat memorable was the inclusion of spunky Rumi, the best friend character. Her personality was great, and the most memorable scenes in the entire manga, in my opinion, all involved her in one way or another. (She had a couple truly great scenes where she yelled at Reiji.)

Still, for all that was good about the manga, the story didn't especially grab me. In large part, I think this was because Rumi was the only character in the manga I truly enjoyed. Reiji was a typical, personality-less bishounen who hides his feelings/only shows his emotions under extreme circumstances, and while Anna had more backbone than most shoujo heroines, you could still easily mix and match her with any other shoujo lead from any other shoujo series. It's not like this mangaka can't create memorable characters (if nothing else, Rumi is proof of that), so I don't know why she'd make her leads so uninteresting. I was honestly somewhat bored by these two and didn't much care one way or another if they ended up together or not. (In fact, I probably would have enjoyed the manga more if they hadn't.) I read the entire manga because it had been fully scanlated when I got a hold of it, but since the story didn't leave much of an impression on me, I suspect if I had been reading it in progress, I wouldn't have made it to the end because I would have forgotten I was reading it.

The manga deserves points for not being Shinjo Mayu or any number of brainless shoujo manga clones, but I can't give it a 10 for that alone. Since I thought it was a middle of the road manga (not bad, but not great), I'm giving it a middle of the road score.

I loved it! I really liked it, I think my favorite character was Rumi, because of how she could stand up to people and cuss them out on whim. I'm very short for my age, I pissed someone off once and got beat up for it, so I admire her bravery.
