Hmm....
Its interesting to see, that the "work" is copyrighted, however I have met quite a similar story over 10 years ago, Called 天使なこなまいき (tenshi na konamaiki)
Before trying to sue anybody, you better make sure if the idea they use is rather taken of the original japanese work.
As the matter of fact, in this topic, its nearly impossible to make a story, which has not been made a manga in japan ages ago.
Right now Im struggling with ideas too, after realizing, that the current plot I made up, ended up too similar with a graphic novel recently came out.
You dont have to be afraid "your idea" is used by another creator, since real creators are attempting to make something unique to them, to their style, so using a storyline which has already been worked up in a way, is kind of unacceptable,
What actually matters: characters, character development, and the graphic style itself.
Therefore it is possible to make unique manga with a common plot, as for me I prefer avoiding to do such..
to me it seems: your idea is viable, but you need some more focus on the artwork, and generating some tension with the character personalities,
For some reason I could only look at the first page, pressing next led me back to it.. I would be interested in the plot, if its worked out, because at this stage, I feel like Im commenting something just by its cover, and I cant determine if I just fail to access further story development, or I simply find that only page, because there are no more pages.
The common school incident startup can be developed into various plots, but its hard to make an objective opinion on a book by just looking at its cover.
I might sound quite negative here, forgive me for that, it was not my intention, Im just being a litle confused.
If there is a full story, pls link me a download in zip, or something like that, because this copyright stuff made me a bit curious. Made me think: you cant possibly want to go through the anoying process of copyright registration for just one page.
I apologize if the style I write my comments is not very clear, english is not my first language. m(_=_)m
*EDIT*
SUMANAI!
I managed to get to the whole thing, which gave me a totally different view: Its not like Tenshi na Konamaiki at all, it resembles a totally different manga.
My appologies.
The thing is: I normally read japanese style written mangas on this PC, which start from the back of the book, so what I actually first saw was the last page, and this is why I kept getting it back pressing Next button, since nothing is after last page.
As for yet, I did not have time to go through of it all, but at this stage, something certainly bothered me:
I dont exactly know, how old your characters supposed to be (their class was not mentioned), but the way they talk/think is just too vulgar/obscene.
The guy with the secret (I mean the main character) got a lot beating at start, but talked like a man often dominating in fights.
I guess (by graphics and plot start) his secret is actually HER secret, which kind of makes the dirty talk more strange, considering he/she does not really kick a**...
Why do everybody talk/think that dirty at their age?
It also made me wonder, what age audience is the comic aimed for?
At this stage it rather looks to be 20+ rated, however characters seem to be more gentle in seinen manga(20-30+)
