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!

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.

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.

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.

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.

I can come up with a better rush ending off the top of my head: He and Oneesan get drunk and he knocks her up. THE END. I mean, they had the vibe going for practically the entire series, and we were all waiting for them to make a mistake.

An ending worse than School Days has finally appeared...

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 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
