idk...this manga is one of the most original manga that i ever readed
but somehow..somewhere...the heart warming story, just became anoying
it is a good plot...but it was too much prolonged,and it has way too much filler now.

about filler...we already have shounen jump to do that
at least shounen jump is weelky not monthly
waiting about one month to read filler is pissing me off

This is a very interesting manga, very unique in the way it depicts school romance. Traditionalists might not appreciate it because it doesn't always make sense, and there's no attempt from the author to explain it either. However, that's what makes it a breath of fresh air in the school romance genre. A good, light read.

2010: Most of my thoughts have already been addressed. Honestly I was waiting for more supernatural elements to return, but its turning out that the girl is just a deviant normal and not some mysterious being as I was hoping. The surreal dream sequences in the first volume have faded out, and the series stabilized, with the setting becoming a normal school in Japan (to my chargin.)

One plothole that annoyed me is how the beginning if the main character didn't drink her drool he
would have withdrawal syndromes and sickness, but by chapter 48 he can go a week without her.
Another plothole is in the earlier chapters drinking saliva could show a vivid mental image of the other person, maybe even a memory...but in more recent chapters all it does is give you the feelings of the other person, which are often misinterpretted by the recipitant.

There are some other examples of the author seemingly reversing himself, but I can forgive that since his first one shot was in 2004. I'm just glad the author had the common sense to let time flow in the series (1 year so far), which lets you suspend your belief and accept that the characters could potentially change in that year...not that they change enough....Considering how much the two interact and exchange bodily fluids and share their feelings mentally, you'd think there would at least be able to hug each other by now....The main character, henceforth to be referred to by me as Rei ayanami's cute emo-kawaii syster, is really living up to the title.

One thing that cheapens the series is it's attatchment to fate. Instead of having characters decide they really love each other for their personality quirks, there's a tendency to say "your saliva tastes better;" that physical aspect is as shallow as saying "I keep dating you because I like the color of your hair, or your breasts are bigger than other girls," and it gives up the opportunity for a monologue and the character deciding why he really likes the other person more. The idea of
being bound together by fate is also a cop-out, since it denies the characters the tension from not knowing whether they'll keep their partner or not.

Overall the series is structured like koineko, with a loyal girlfriend devoted and bound to her man. While I enjoy reading it, it has become more of an escapism than the what-if of the surreal beginning, and I hope he just hurries up and has the characters kiss, hug, make-out or do whatever they need to advance to the next stage of development and dramatic tension.

2014 update:
Everything I said stands. The ending was dreadful...absolutely nothing happened despite nearly a hundred chapters. The poor sexually repressed kid stays sexually repressed. I advise against reading this manga past the first volume. Trust me, there is no further plot advancement, and no closure.

Patience worn out

I put off reading this series when I first saw it because I thought that the whole drool thing was to weird for me. Then when I started reading it I was pleasantly surprised by its charm and novel concept. Skip 30ish chapters later and I feel like I'm forcing myself to just catch up so I can stop and at least say that I gave it a try.

Like in a relationship where minor, annoying habits become huge problems years later I just couldn't put up with it anymore. We are told at the beginning that male lead will be the female lead's first and they already got this drool thing going but then nothing happens. Literally the only progress in the main relationship is that on the condition that male lead would otherwise get hurt, he is allowed to hug his girlfriend, otherwise he gets attacked with scissors. Okay, I know that others might prefer a slow pace but come on. The pace is so slow it makes you wonder if they're moving forward at all.

I got bored for several chapters, maybe because of some repetitive humors. However, up to now, for me, the plot is still not too bad, kind of compact, and everything seems to make sense. And I was sort of moved for several chapters: for example, the one talking about him and his sister in the festival.

People doubt that this series will end in two or three chapters... I did not want to accept, but I think they might get the right prediction; I kind of hoped it could last for a little bit longer.

Well, hitherto, there is no way for me to rate this higher than NHK, which I finished one week ago and I gave 7.5...

First of all, I love this guy's art. His previous work (like Discommunication) was overwhelming--each panel looked like one of the occasional "dream sequences" he puts into X. Here he's opened up the space in his art, concentrating on the characters, and developed a new, lighter line with less spot black. And it's all a matter of taste, but I find his girls as cute as hell.
Some previous reviewers have commented negatively on things like how Urabe won't let him hug her, etc. But I disagree. Remember, Urabe said right at the beginning of the series that he's the man she's first going to have sex with. And as you see in the story, each step along the way is not only controlled by them, but, in a way, by their "bond." Urabe doesn't want to move ahead of where that mysterious "bond" wants them to be. I admit it's a little slow. You'd think that when she starts getting sexually excited due to the progression of the "bond," things might heat up a little more than they have. But it's just not "that kind of comic," apparently. Regardless, there are always lots of fun little stories and Ueshiba's fascination with how sexual relationships develop between juveniles provides him an opportunity to experiment, playing "what if?"
Fan service? Sure. But it is, after all, about the relationship between two teenagers who are "destined" to be sex partners, and a few panty shots are not exactly out of bounds. You've got to give the poor sex-starved boy something to get nosebleeds about, after all.
So far I've enjoyed the hell out of it, more than any romantic comedy I've read in years.
The recent Imai storyline has me a bit concerned about where's he's going, but it's fun to see Urabe be both reluctant (in her usual way) and and the same time kind of intrigued by the unique opportunity she's being offered. She could certainly tell them to go pound sand and walk out, but she doesn't. Even some of her dialog was charmingly cute and hesitant at that time.
Anyway, I look forward to reading it every month.

Weird but to my taste.

One word to sum it up ... Weird.
BUT it's not unlikeable, in fact I even loved it (10/10) and I definately do not have any kind of drool related fetish.
The art is ... um ... good in it's own way I guess.
The male protagonist is your average boy while the girl is mysterious, weird and (in my opinion) likeable.
Even though I think of this manga as weird, it doesnt make you think too deeply about it, it even manages to stay lighthearted and refreshing which is what made me love this manga in all its weirdness (I think).

Took about 10 chapters before the very concept this whole story is based around stopped making me gag every time it came up. Ignoring that, there's a lot of unconventional, yet fanservice-y stuff that's likely the cause for this seties' high rating. I will say that the first volume or two felt really brilliant, as far as using unique ways to present the idea of romance and sexuality, but that was quickly lost due to repetetiveness, and a general lack of direction in the plot.

I still thoroughly enjoy reading every chapter of this, I just wish I felt like the story was going somewhere, and not simply being dragged out in order to sell books.

Sometimes it can be a really cute, and sedately funny series. Other times the side characters can be so annoying, pushy, and manipulative. That is the part I dislike, almost all the side characters are like this too, and it comes off very artificial and not funny. Some are fine like his sister and friend, and others don't have it as bad all the time.

There was a time when I thought the two's dynamic might had started getting repetitive but then the writing got interesting again. In fact, I'd say most of the arcs aren't all that good. They aren't at the heart of this series.

Underneath it all, it's a romance story, but with a not so natural twist. Good as a relaxing read, but if you want something though provoking, this is NOT it.
