This manga really shows how you can be who you are, but still grow and change to nurture relationships.

LICENSED NOW! Kodansha picked it up! biggrin Super excited about that. Even though I've finished the whole series, I will still support the Mangaka by buying their work.

First off, let me just say that I don't read a lot of shoujo manga. And this is, unmistakably, a shoujo manga, with all the qualities that the shoujo genre generally has- sparkles and all. With that being said, this is still pretty dang good. Good, expressive art, for one- I can easily tell all of the characters apart. They all have unique designs, and it's a great departure from the usual cookie-cutter people who just have different hairstyles. There's good backstory to the characters, too, and there are a lot of unique issues brought up and different situations. It's sort of refreshing; it doesn't break out the mold completely, but it does stretch it, which is nice.

The characters are likable, too. Shizuko, the heroine, is a unique character- emotionally dense, but not obnoxious about it, smart, ambitious, hard-working, and cold. She has her cute moments, though, and Haru, the male lead, has his absolutely adorable moments, although he is childish and irritatingly dense. I find that's a trend in shoujo manga... unrealistic emotional denseness (density?).

And that's where my conflict lies, in the emotional aspect. I really enjoy the story and the characters; the romance is sweet, and everything that happens generally tugs on my girlish heartstrings. But gaaaah, some of the events just... arrrrgh! FRUSTRATING!

Since this is a manga that focuses on the romance and lives between the characters, and it's already eleven volumes long, there's obviously some love rivals and conflict thrown in. But honestly... seeing the love rivals makes me think that the two main characters shouldn't even be together, haha. Yamaken, for example, just makes you want to tease him and be his best friend. He's just so lovable, it breaks my heart to see him totally ignored by Shizuko. All the other characters have a lot of care and development put into them, even the side characters like the love rivals and Natsume. It makes me want to shout at Haru to grow some common sense and goshdarn develop already! He's seriously like a little kid- super possessive, dense and confused, aggressive, selfish, irresponsible... and occasionally ridiculously adorable. Occasionally. But, like I was saying, unless the main characters shape up and get on with their relationship and connect better, I can't even root for them. Which sucks. The other character's relationships and love just make me not like the main characters as much! It makes me conflicted, since it's a nice story, but I literally can't stand to read it anymore. It's sort of painful to see Shizuko and Haru's relationship go by in slow mo while other stuff happens. I wish the author would just get them to directly interact and develop! Random things happen, rivals pop up, and the actual relationship between the main characters that got us hooked in the beginning is completely shoved to the side so that the story can get a few more volumes in.... ugh.

I was reluctant to continue to read this manga cos I actually dropped this series a long time ago. However, I decided to watch the anime yesterday and you know what.. IT'S AMAZING UGH. WHY DIDN'T I REALIZE IT SOONER ?!

I have no idea, I used to find this manga pretty boring though. But omg, the anime version is SO GOOD. I love the characters, they're all lovable \(^.^)/

I fell in love with Haru. He's such a sweetheart. I loooove him when he's together with Shizuku. They make such a cute couple.


Awwww he's a cutie. I love how he always blushes whenever Shizuku starts talking to him. But I guess he doesn't have a chance to be with her in the end. Aaah. But I'm still rooting for you. <333333333

Why did the anime end so fast though? I hope there's gonna be a new season soon. I'm looking forward to it! smile I've decided to read the manga again, it's not as good as the anime though. I prefer the anime version, but it's ALL GOOD. At least I get to see my Yamaken-kun lol. <33333333333

Overall, I had a great time watching and reading this series. Totally recommend!! smile

I like how the main problem in Haru's and Shizuku's relationship are their personalities, obsessions and priorities (not some dead lover, abusive family, traumagic past, different social standing, forbidden love etc). Sometimes their point of views clashes and is out-of-sync. It makes their bond much more fragile than it seems, but it also shows how much they affect each other. That fragility is also caused by how random their attraction towards each other is. Neither Shizuku nor Haru always magically say the right thing when it's needed. It shows the subtlety, the complexity and the charm of 'opposite attract'. Not just 'no-matter-what-I-still-love-you-the-most' crap or the convenient 'our-differences-compliment-each-other'.

Another plus point is at how everyone in the group is intimidated by one or another in some way or another, yet still each of them is nice kid with hearts and lovable quirks, and they are growing. Especially the complex Shizuku has toward Haru. Usually you get this rivalry-turn-love kind of thing where at the end of second chapter all the malice intentions is vanished like it was never there (yeah since love between two middle schoolers is the greatest thing in this world). But TNnK takes a different path. The rivalry is growing one-sidedly on Shizuku's part, together with their growing attachment to each other. Haru is no some simple and boring prince charming too. He is compassionate yet violent, bright yet dark, weirdly possessive, and he is only able to naturally thinks about himself (weird yet interesting, because usually it's not the kind of flaw you find in shoujo male lead). He isn't some manipulative bastard pretending to be all smiley and act like a brat, he IS a child at heart. He is showing his love toward Shizuku all openly, yet up until now I'm not really sure in what way Haru loves Shizuku.

Great slice of life shoujo. I see that not every reader gets the same sentiment as I do, which is their loss I guess. Some joseis aren't even as 'mature' as this manga is. I've read hundreds of shoujos, I know what I'm talking about and I'm not that desperate that I praise anything that shows some differences compare to common shoujo.

Really if you don't like shoujo you're not going to find anything in here that you like.
This series does a good job of setting up the girl, but it somewhat superficially attaches the male protagonist to her (but manga demands you get things rolling right away and not ease into it, so it's forgivable). The other relationships feel more natural in their development.
Only the Male protagonist in this manga is really abnormal in his daily and social behavior, however his thought/reactions to his relationship with the female protagonist fall in the normal range for a character with his background. The rest of the cast feels very believable in their interactions and reactions. The think I liked the most about this series is that all the character interactions and reactions feel very natural, I was never left thinking "well that's out of the blue".
The art is doesn't stand out as being great or terrible, it's on par with other similar mangas.

Read: 39ch (chapters are double length ~40p)
Rating: 5 of 5 (non-shoujo fans 1 of 5)
Typical slow romance shoujo with most of the plot focusing on it, side character's romance, or every-day drama.

It is surprisingly well-made despite it's simple plot.
I suppose it's a slow paced, but the character development is spot on. The story definitely caught my attention and I love the details the mangaka put into the side characters. If the story continues like this, I don't mind the slow pace because it's that good. Also: mangaka is excellent at weaving in the side characters into story. Worth reading their stories as well.

I must be honest that Haru x Shizuku is not as interesting as the beginning. Dare I say that the side characters are more interesting than the main couple? I guess the main couple needs a bit more work :')? But i Definitely recommend this.

I have only love for this manga at this point. If anything, Haru's weird ways are just cute and the way Shizuku responds is usually even better. The side characters are also pretty well rounded, considering how little time they have, and I have to say I was actually sad when Yamaken didn't get a better shot with Shizuku, while still being GLAD he didn't. I was in a tough spot! Personally, it is a manga I probably wouldn't have looked twice at in a store, but I'm glad I picked it up! XD

This is the Only shoujo or manga that I've read that has a realistic approach to being socially outcast. Even so, It could still be done better.. I read tons of manga's and especially shoujo's where their was a socially outcast main character or side character and suddenly they get a bunch of friends and life is lovely. This is actually kind of borderline that ideal a bit right now, however it started out more realistically so I will give it that. I am STILL looking for a manga that is NOT like what I described, I will let you know if find one. Basing this manga on what it is, it is quite good, enjoyable and Shizuku sticks to her character as well as Haru. This is more of a comedy manga than a romance, but I'm fine with that since the comedy is actually interesting.

Short version: Closest manga I've seen to being realistic socially, but sadly still not quite there.

Can I just say how much the characters in this make it awesome. Its very good the plot isn't cliche but it does have its moment. The relationship between Haru and Mizutani is very boring. Because honestly, Haru needs more development. He has had zero since the beginning. I feel like he's dragging the story down. Now I don't dislike him but I just feel like he needs more past time or something so I can understand him better and actually like him. Everyone else is perfect. Read this!!

This manga is amazing to the brim. Exciting, cute and funny. It is definitely one of my top tens. Unfortunately, dear future readers, be aware of the fact that Yoshida Haru has a thick skull.
He may have genuine interests towards Shizuku but what do those 'interests' actually mean? Love as friends or lovers? THIS, is an issue for me. I nearly flipped a table due to his bluntness. Haru could have just made things CLEAR. Take Shizuku and leave any other unnecessary girls! (I may seem cruel but I am itching to say so). But overall, the manga is good.
