I don't regret reading this manga. To me, it's truly a tranquility.
Art-wise, the sceneries drawn in this manga are all beautiful. And it captures the 4 seasons nicely! Aside of that, I really like the body gestures shown in this manga as well. When it comes to the adult scenes, there is no single unnecessary fan-service. It's romantic. It's mature, in a good way. And there's some little cute part as well XD
Story-wise, it's kind of "divided" to 2 path; romance side, and real-life experience side. I like how the mangaka portrays the male character who wavers between his future path as an artist. I also like the development of the characters, both Akira and Tetsuo, and even the secondary characters....
..........until the love triangle thingy starts. DAMN DAMN DAMN DAMN........ If only Hanami stays an "inspiration" until the end, things would have been better. It is such a nice thing that Tetsuo saw the book and cried during the last 3 chapters. It is a good thing that they confront each other for the last time before they say goodbye for real. If there is a continuation of this manga ever, I can only hope that Tetsuo can stay with Akira forever.
Speaking of Akira, I really like the character of this woman. She's gorgeous and mature. But sometimes she can act cute and a little bit over-confident. Still, she is a very strong and understanding, gentle at the same time.
Despite of its ending, it's still one of my best mangas ever. I am quite sad with the ending, but I won't say it's a bad manga just because of that. Why? Because I feel like when their story keeps continuing like this, one day, they might be together for real XD
