I haven't felt like this in so long. This manga was just so absolutely mesmerizing. Easily a favourite. The plot, if crazy, was nonetheless magnificently executed, so much so that I surrendered with little to no effort on its part. The characters are fleshed out to near perfection, the art is simple, lovely and gorgeous, the smut is great--- ah, what's there not to love about this work.
I don't particularly care for child-parent incest but I have read my fair share of them (of course, otherwise I wouldn't know if I cared for them at all). Therefore, I must admit I was quite ready to turn this down after the first chapter or so, even before I reached beyond the cover. I was not prepared, however, to fall so deeply for these characters and their tale. It was a turmoil of emotions page after page: the subject of incest regardless of genre is hard enough to swallow as it is, but here, with time-travelling as a major plot device (surely we all noticed Konomi and Ryou weren't the first to undertake on this adventure), the whole issue is put entirely into perspective under microscopic lends. It's not a matter of why is this love between a parent and a child, which started so long before the latter was even born, wrong or unhealthy or morally reprehensible. Ryou knew who Konomi was in the past and he still couldn't stop himself from falling in love - perhaps because that Konomi wasn't his dad yet, and yet he was. Where does that leave Ryou's mother, the older woman whose eyes were of such a strange brown Konomi would have never seen before if it was not for that man who once appeared in his yard out of nowhere - who, again, was light years away from ever existing. What of her, who was but her own child's replacement in the past and in the future. What of Masa-kun, that man who Konomi loved or think he loved but was, then, someone else? And what of Konomi himself, where does he come from when his own grandmother, we know, has seen her husband suddenly appear on that same yard (far worse than not knowing how he did it, we don't know from which future/past/dimension he came)? The web of relations is much deeper than you would imagine, that's why I say this is not merely a case of taboo and morals - of course it is also that.
I'm sure that, whenever I reread it (because I definitely will) I'll find an even greater world within it, ahah.
