Kono Onee-san wa Fiction Desu!?

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!

Decent series, ending will make you feel this was a waste of time though. Go check out Golden Time/Nande koko ni sensei ga!? or Yakumo-san wa Edzuke ga Shitai which are far better than this series was.

Hell, I couldn't make it halfway through this one biggrin

Sorry, yeah, this was like watching freaking paint dry.......I mean, yeah, I like slice of life type elements in a story and all, but jeez, you've got have at least some kind of connection / likability with the main characters before slice of life will fly on its own. And no, nothing, just a boring story that wasn't really going anywhere with characters I really didn't care even a little bit what happened to.

I don't know why people didn't like the ending. I read it while it was still ongoing and actually such ending seemed good to me... Back then i didn't feel the need to comnent, but seeing all the negative comment i want to give a different opinion.

I actually always root for the girl who is most passionate for the boy, and if that girl isn't female lead, well i still root for her. So i was rooting for Ririko to begin with, and i think she totally deserves beign his GF in the end.

Frankly I don't quite care who's end up with who. I never seen the serie as something with romantic goal. I enjoyed the formative of both Jun and Narumi before they met, their interaction after, and ultimately their character as a whole. I don't mind the romance remain unresolved, because I think that's not the selling point, but merely an attracting point. Too bad selling subtlety after promising steamy romantic comedy is unacceptable by Japanese reader (or reader in general). The manga is a solid 8 before the rush, it's 4 by the end. I hope mangaka write another serie because this title, before its eventual axe, is quite refreshing.

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

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.

I REALLY REALLY enjoyed this Manga!
And I loved how every character was very lovable and build to satisfy their role.
But come on...axed or not...gimme my ship.

Whatever! It is a great way to consume some time with.

A fun series

This series was filled with so many warm lovable characters. There's many funny moments, many awesome moments, ero hijinx and one silky smooth operator of an MC. Haha I had a blast reading this.

I was surprised at how charming the mc turned out to be, with the synopsis you'd think he'd just be the typical harem anime wuss but he turned out to be down to earth, friendly and most of all realistic.

Also don't mind what other people say about the ending. It was fine. I only wish the series could of lasted longer!

About as much spoilers as everyone else:

Let's face, it a good chunk of the shown relationship building between Jun and Narumi is fanservice and comedy. I'm not saying they didn't grow closer, but it was never in a romantic way. As they both reflected at the end, she had become the role of an onee-san to Jun.

That said, I didn't particularly liked Narumi, and had put this manga on hold for a long time because she was so annoying in the beginning. But come on, were you really expecting them to sail with the 12 year gap ship? Every single couple was paired up normally.

My recommendation is to ignore the emotionally charged comments about their sunk ship and expect a decent high school rom-com with a live-in onee-san being the special factor.

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.
