The art is really clean and enjoyable, though the plot isn't the best. Its kind of predictable in a way, but since this isn't completed yet there is still a chance it could be executed in a good way.
It was cute so far, but I am not a fan of incest so I am rooting for Akira, but he is kind of annoying at times. Tomoharu is a nice dude but he needs to calm tf down, he's petty so he has the chance to be with literally anyone. Yuki is cute, thought pretty one dimensional and Natsuhiko is pretty straightforward.
I am rooting for some more character development from Akira, and I hope that some will happen for the brothers too but I doubt it.
Like I said it is not completed yet so I can't give it an overall score but I can give it a 7/10.
Unless it somehow dissolves into incest, then I'll rank it lower.
Please don't dissolve into incest, I'm begging you...
