I have read yaoi mangas for seven years now and only a few times I have found a story that moved me to extent this one did. I might be biased because I have followed the works of the mangaka since she was a doujika but I can still say that this story was solid.
The plot seemed to be like any other but as you read the story you realize that Kazuki sensei really put an effort to make the story stand out. It was sad and lovely.
The characters' personalities were realistic if we think of the story as something that could happen in real
life plus their feelings were almost graspable, you could really feel the way they did.
As for the art, you can see a resemblance with her doujin works (which were about Haikyuu) but they're beautiful nonetheless.
So, if you like stories that make you cry and happy at the same time a.k.a fluff and angst, you should definitely give this a try!
PS: this story is shounen-ai not yaoi
