First the art: It's from the 90's so it's different from the style which is now modern. But it's really OK, I could read the facial expressions and the bodies weren't drawn wrong/unproportional, well most of the time g. The background is drawn good and generous enough to have a good feeling of the location in witch the action are taking place. But except for the facial expressions of the characters the art isn't really breath-taking or captivating. But the art is miles away from being bad either. It's a pity that now-days most of the mangaka don't draw real facial expressions.
The story: The most mangas, witch are drawn in the 2010's, are drawn for a special target audience. I don't have the feeling that this manga was drawn with a special target audience in mind. So to put it in a genre like Seinen is somewhat arbitrary. And if this manga has to be in a genre it should be Josei. But Josei is targeted for grownup women and the main protagonist is a man. On the other hand the main female character, who drives the story forward, is a really modern women.
It's difficult for me to identify myself with the main protagonist, he is a looser in the end. He can't embrace what he get. I don't mean that he isn't greedy, this is actually good, but I mean the personal stuff like the girlfriend or the like. He want everything to be like it "should", in terms of the ossified, Japanese society of the 90's. In the end he is a boring man, only the people around him make his life a rollercoaster and interesting. And he likes to run away or chicken out if he is left alone and has to do something important for himself. Also he has has few till non character development, witch is OK if it was planned by the author for the character. Not everybody change after time, but most do. The other characters are very cool, lively and i can imagine that i could meet some of them, or all of them, in real life. Most of the time all "decisions" made by the characters in the manga are made because the character would probably do this so in the specific situation. Only sometimes let the mangaka the characters make something little(!) strange. The story it self is also not very far-fetched, not much at least. And the rollercoaster is funny to read. And because the story has the feeling of a real-life story and not a typical, whimsical Shoujo, it's sometimes little bit difficult (for me) to excuse and live with the looser in the main protagonist. But the other characters in the manga makes up for this "weakness" by hundredfold.
The end is weak, but OK. I could live with it but I was not enthusiastic about it at all.
Conclusion: Good read. Take your time and enjoy the story. But be warned, some of the characters seems to be little bit to "lively" and it is only about human (especially male-female) relationships, so you will find no evil organization or crime in this manga. 😉
