I was a bit disappointed when I read it. I usually like a lot Nekota sensei's work, but this one just doesn't got me.
First, for the series of stories, that it's lasting for 4 volumes (and it's not finished!) is a bit too long for me, as you don't follow the protagonists along the volumes. It would have been better if we were following a bunch of couples all along, but we have new couples here in each volume so we don't have the time to get really attached to them.
Plus, the environnement of an all-boys catholic school feels more like a pretext for gay love than a real element of the stories. The questions of guilt due to the religion seems to be simply put aside as if not important. So in the end, the result would have almost been the same with or without the catholic element, it's getting kinda boring. This added to the fact the stories doesn't last long, they end up lacking depth and feel a bit superficial.
But, I still rated it at 6, and I have to say that it's thanks to the great art of sensei. As she's taking her time to describe the loving scenes, we have the chance to enjoy pages of details and kisses, which is really good.
And as the characters are quite well presented, if you can overlook the environnement and the clichés situations, you might end up going from a story to another. So if you're feeling bored, and just want to enjoy some silly stories with great art, this series is for you !
