This is one damn pretty *beeped* up anime
I don't know how to start. I am not into romance but this anime had more than romance. It was about how relationships can be screwed up at its worst. Although it was only 12 episodes long, it makes you feel like losing your mind becuase the main character is so characterless you want to break every bone in him. Actually the whole series is like a long nightmare.
I have rated the series 7/10, it was a decent anime, had an interesting plot and variety of characters. As for cons, it repeats itself many times, some characters are underdeveloped especially the main character. Is full of cliches, especially the ending.
I recommend this anime to casanovas out there to see how involvement with multiple ladies may end up. I know that the series is not that realistic but the effort is remarkable.
Btw, I really felt for Sekai, she has no fault at all this and we don't know if she was delusional and really had a baby. I would rather trust Sekai than Katsura. I started to hate Katsura after she started to insist that she and Makoto were going out while he was already screwing other girls. She looks like innocent but her delusional mind and obsession is a complete turnoff. Makoto was holding the strings throughout the whole story but he was so irresponsible and stupid he ruined the whole thing. Anyways, I can not blame Makoto or the bitches, they are the main source of this intriguing piece.
Additionally, I think these event are more likely to happen in japan due to their extraordinary culture. First of all the kids are overly distant from their parents. Secondy, they do take dating too seriously. For example they confess to each other, which I think is extremely stupid. They go and say all of a sudded, "anu, anu, anu, I love you." WTF? Then the other one instantly accepts it and after that day both brag about their new mates around their stupid friends. And there are no ethics regarding sex in Japan. Having no Taboo about sex is not a bad thing but it should not be a toy for children. Those love hotels, and japanese...
I've seen things you people wouldn't believe.
