Because of changes in seating arrangements, high school student Tsuda ended up behind the quiet and expressionless Endou. Their interaction is born from a trivial incident, and he begins to see Endou who he has never gotten to know before. That mole, slender nape, and soft hair. The subtle faces that he makes and little changes in his attitude. But Tsuda, who used to be indifferent about others and never made any deep connections, now feels impatient about the distance between him and Endou, who he has been gradually getting closer to. What on earth is drawing these feelings?

I want more ,the story was short while there's more can be tell.The way the writer did the story line made it feel like different plot from other similar yaoi manga,the only objective,although it did't effect the story from my point of view,the missed up events and dialogue the writer would done better job in giving a little clarifying view of the scene
love it great story lovable characters

Hayakawa Nojiko-sensei is GOD

How can anyone not love Hayakawa Nojiko-sensei is beyond comprehension to me. Every single panel, and character movement in this manga is not only absolutely gorgeous but essential. Really, I can't find a single flaw here. Not one.
What I loved most was the (sexual) tension that undergrid the character's interaction with each other. I couldn't stop "kyaaaaa!!" and hitting my head on the wall. SO CUTE (>.>)

Very cute. Pretty repetitive in the context but makes it poet in a way. I guess Endou liked Tsuda way longer then huh. Endou's hair really does look soft, like a Yorkie, probably hahha. I liked Tsuda with his hair down. The hair cut scene was funny.

I just LOVE this manga so badly

I don't want to spoil it for everyone so I'm going to be brief, but I seriously can't help myself squealing at how much I love this manga and Hayakawa Nojiko-sensei. She truly managed to leave a deep impression on me with this series particularly. While one might find it hard to read through all her panels I had no trouble at all, in fact I often found myself lingering at a spot once in a while just to truly savour and admire her beautiful artwork, and I did that with a passion.

PS: The sexual tension is just flying off the hook. I'm eagerly waiting for a group to pick up the sequel to this one and see how things'll turn out, hopefully we'd finally be able to see some real 'actions'.

The plot is simple - if you're looking for elaborate declarations of love and jealousy, this is not it. This is quiet and lovely and relies not on dialog but on scenes and expressions and basically reading in between the (few) lines.

It feels a bit like watching snow fall at night. It has that kind of atmosphere. It was really nice. smile

I like how this author gets us to the people getting together (it's always done so wonderfully), but I also kinda wish we could see what happens AFTER. But that's probably a whole other story.

i found this manga almost...poetic in its presentation of images and the paneling. dialogue is limited since the mains themselves aren't the type to talk much, but so much is expressed in how they see one another and the things that are going on in the background (the kiss on the train platform scene comes to mind) that you feel instead of know what is going on in the character's minds. i agree with the character chiba and infinity that the kiss was freaking HOT. and this is just a shounen ai ;_; i also love the way the minor characters were constructed and characterized. they grow on you as well.

this was just plain fun to read! I love stories that deviate from the same-old-same old yaoi story. This was like a gulp of fresh air! Ugh, and that kiss at the end! The couple's chemistry is just so captivating. I love the characters, too. No one is just a charaicature, every1 has a purpose. Anyway, read it. It'll make your day better.

I don't think this is the most accessible manga out there in terms of that there's so much subtle meaning in each panel and the way the story is told is completely out of wack. Most people are going to dismiss this as boring (not that there's anything wrong w/ this opinion), but for people who like those mangas that are crazy weird this is a must read.

It's a very surreal manga (i.e. Oyasumi Punpun or Annarasumunara), and quite often you'll see that what Endou and Tsuda are feeling isn't said but is expressed through pictures. Like the whole first scene when Tsuda suddenly sees Endou being twisted into some sort of pseudo-sexual position can be taken as the beginnings of his attraction to Endou. I could honestly write about 15 pages of analysis for all the subtle/surrealistic elements I saw in this. If you want a fairly straightforward manga that you don't have to sit around and analyze then this is not for you.

On the whole, I thought that Endou had quite a bit of character development for such a short series, and Tsuda was much more than just a cardboard cut-out of a character. And man oh man, is their chemistry hot. I'm ok reading through hardcore yaoi and then I read this kiss scene and I'm like "WOAW THERE." That kiss scene was probably one of the most sensual I've ever read.

Overall, I felt it was a fairly nice read that made me sit around and think for a bit. Sure it's not perfect and it's not the best BL out there, but for me, it definitely was not boring. It's a polarizing manga, just like surrealism as a genre is. Try out it, and you might end up with something you really like. Don't go in expecting the same old angst found in BL about high school students.

Different, in a good way

The art was a little sketchy but i guess that is what made it so appealing. I found it incredibly cute the way the two got together and how, despite the lack of dialouge, they still came together. Even till the end, none of them said they loved each other because it was something so obvious and was not expressed through words but with their emotions and passion.

The story was calm and i like that the order was different and that the storyline wasn't just linear, but went in different directions and to each ones version etc

However, i didnt understand the whole pencil with the number thing?
