I started to read this manga because I was fairly interested in the development of Hase and Kaori's relationship after watching the anime. If that's the main reason why you're thinking about reading this manga I can reassure you that it will be a waste of time.

First of all I can only state my opinion after jumping into this manga after I have finished the anime. I really liked the anime and how the characters where interacting with each other which is why I wanted to give the manga a try.

The art still mainly stays the same but the way the mangaka illustrates the patterns read more

Good manga but...that is the feeling i have

The art without being of my favourites its good enough not excellent but well made.

The characters,
The main characters are good developed maybe a little bit longer it could be better, what i feel its that some things get dropped but not resolved, but at least they struggle with their feelings in a good way.

the supporting characters are very poor. The mangaka leaves some ideas about them but never develops anything and only use them to fill, at least two of them.


The idea is quite interesting and some of the feelings during the story are well driving read more

Imagine a manga where it setups a bunch of unique problems yet follows a romance in which both parties feel this need for one another yet it doesn't fufill on the romance aspect in which it's tagged.

That's isshuukan friends. The premise is interesting enough to garner attention and the growth they go through is immense, Hase's whole character arc is that he's finding what he wants but its clear that what he wants is different from what he says yet the author doesn't explore that at all. He talks about it here and there but in the end Hase ends up friendzoning read more

Having read 11 chapters, I have given this manga an overall rating of 8. I have greatly enjoyed reading it and wish a lot more chapters had been released.

PROS: I like the fluffy art-style, I enjoy the story, the characters are cool people, the story progression so far has been good and well paced and its 4koma style fits it well.

CONS: It releases rather slowly (though this is probably the translator's fault) and there are some minor plot holes when dealing with the girl's memory capabilities.

The first chapter is a very good indicator of what the rest of the chapters feel like and read more
