Late one night when Jun was out on his bike, he came across a drunk, half-naked girl sprawled on the side of the road. She came to be uncomfortably affectionate, but Jun took her to his home to sleep it off with gentlemanly discretion. It turns out that she is Kawase Narumi, his author mother's new assistant. Unfortunately, she has no idea what she's doing in her new job, so Jun's going to have to coach her. He's also going to have to deal with her habit of getting drunk, mostly naked, and cuddly. Jun's life will never be the same!

It's what Anedoki should have been

Depend on how well you can take this pairing. I on the other hand don't mind it at all, as long as they have the resolve to see it through. It's definitely a genre that has been rarely touched upon, cause the idea of a younger male being in a relationship with a woman their senior, nowadays is still foreign to most common people. The entire summary of the recent chapters is a question of "will they or won't they?" as these two odd pairings continue to understand each other.

One thing I liked about this manga, is the subverted maturity and gender-role between Jun and Narumi. Jun is 16 years old and is still experiencing puberty, he's is diligent, hardworking, understanding and compassionate with a few female traits such as being to perform several household needs(cooking, cleaning, scheduling etc) which is originally a stereotypical female role. Narumi on the other hand despite her attempts to look mature is incapable of performing any feminine role, in managing herself (much less others, a role which Jun is able to fill in) and has major shortcomings such as being a bottlefairy much to the chagrin of Jun.

Overall I look forward to what the future of the manga have for this pairing, they may end up with each other or they may end up with different people, at the end of the day it doesnt matter. It's all about the character development as how these two support each other, while letting the comedy ensues.

Bland at first glance, but it's actually filled with subtleties

At first glance this series looks like a typical "it's a joke" and later a "it's meant to be" series about the main character Jun and the namesake character of the series, the onee-san figure Narumi. One of the biggest draws of the series is that it toys around with the idea of love, it completely paves a path for this to become a full fledged romance between this "unlikely pair"; however we never really get the answer if they are going to "break the mold of common sense" (the age gap is over 10 years) or not.

At first the characters seem "to perfect to be true" (Jun) or "to sloppy to be true" (Narumi); but the more details are unveiled about the characters, the more believable they come to be and the more likeable they become to the reader. Do take notice that by "details unveiled" we have there are not extreme conspiracies or great secrets hidden within the manga, what we get it's that we learn more about the different characteristics that compose their characters.

All in all, the series has shards of a non serious school story (in series characters even joke with "how right" is a Narumi x Jun pairing), dots of serious romance, spoons of romantic comedy and seasoning of a slice of life story. The main characters show their personalities right off the bat and develop more pretty quickly even though they are in a non serious environment and the support cast is not only "just there", while they might not be omni present they do have a value as they provide strong points about what's going on and what could happen later and provide a reason for what's happening to our main character pair..

Of course, I'm quite interested on seeing if Jun and Narumi do become an item, and with that I'm also interested about how "how far" they can go and on "how serious" they can be to each other.

Well, as far as I can see, this one turned out to be quite promising one.. The characters are likeable & tolerable.. I don't think its quite generic compared to other generic & overrated mangas.. For me, I still need some "human-like" stories compared to everyday something extraordinary will happened kind of story..
EDITED (current opinion): NOPE!!! JUST NOPE!!! HUGE WASTE OF TIME!
Better back away from this series with an awful ending!

It had a good thing going building up the relationship between the MC and Narumi; but NOPE the MC ended up with that mousy little girl which I'm sure no one actually liked since she had little to no character development whatsoever and isn't interesting in anyway at all and is frankly just really annoying.

I can understand that the series was axed, but I would've been happy with an open ending hinting at a possible relationship with Narumi and the MC. But unfortunately the author decided to go the safe route.

Is love on the horizon?

First, I agree with everything kidwith69 said in his review.

Second, as we have gotten to know the two main characters better in the story, it has become increasingly clear that they might actually become a couple! I think the dislike that exists in most places of older man / younger girl parings may not be as strong in the reverse situation. If so, we could see develop in this story some of the moderately transgressive kind of behavior that manga so frequently hints at in order to titillate the reader.

Many a real-world youth over the years has longed for the love of an older woman, and some have received it. So maybe in this story also?

What sort of storytelling is this?

So i gave up around the 3 volumes mark as it was only ok and harem elements started to set in. The ending though caused quite a ruckus it seems so i flipped through very quickly to get to the controversial part and it is indeed street trash of the highest order. One more upvote for Rushed Ending / Axed it is!
What was even the point of telling the already paper thin story if you end like this? NO ending would have been better. At least it wasn´t porn but my score now went form 5/10 to 3/10 as such matters just can´t stand.
This is what happens if you let hentai hacks run wild with no guidance (or talent). Read these quality Older Female Younger Male romances instead to fill you craving: Boku no Chikyuu o Mamotte, Futari no Renai Shoka, La La La, Natsu no Zenjitsu, Ookami to Koushinryou, Otoyomegatari, Sachiare!, Sensei o Mite Kudasai and Yuuki Shizuka - Senior. Some of them are even porn but none will spit you in the face and this is coming from a man who couldn´t have cared less about the ending but somehow did.
Dear aspiring authors take notes here and do NOT repeat such a free fall.

This was going to be a 7 or 8 maybe even an 8.5
Since despite having cliches and stuff it had good depth and development
That was .. Until the last 10 chapters... Where even if rushed it could have still been a 6.5 or even a 7 depending on how this guy executed it.... But no he just had to do it the worst way possible with the last chapter so bad that this whole work is down to 5

anyway I don't recommend it.... Dont read it.. Since you'll go through the same frustration... Not the good kind...
Sigh I really want some more good older female younger male seinen romantic comedy... That isn't ruined somewhere

I seriously don't recommend it. The whole story becomes useless when you reach that crappy ending. It was a 9 before. I understand it was axed but the story made a u turn. I feel like i read a 10 year old girl's diary. Do not read.

This series was cut far too short for much plot development to occur. A damn shame really as it started of interesting enough sad

Ah well, looks like I'm probably going to forget this manga even existed in a few months time.

Man that ending was unexpected. Like Mangaka was kidding, laughed hard after the end.

Spoiler (mouse over to view)
Until the end, it looked like Narumi and Jun was going to be lovers. Age gap isn't that important. But Manga took the last turn before the bridge, made Ririko and Jun lovers. Yeah, Ririko is cute, but why we took all that trouble? I think someone put a gun on Mangaka's head and made him draw this ending.
