Well, this is a drama anime about this dude (Matoko) who takes a picture of this one girl (Kotonoha) he likes and before he knew it; he was hooked up with her. However, Matoko begins to lust for other girls in his class and cheats on Kotonoha for them more then once. Sekai (the chick who paired the two up) was the first girl that Matoko cheated on Kotonoha for and she gets jealous of the two later on when Kotonoha forgives Matoko and the two make up.

That's basically what the anime is about. There's a lot more to it then just that; if you want to know more, go watch it yourself. I found the first five episodes to be really boring but things really began to get intense at episode 6. So that's why I like this anime a lot.

Ugh, the only two characters I couldn't stand were Sekai and Matoko. Go watch the show yourself to see exactly why I hate them; most likely, you'll hate them too. But I hated Sekai a lot more then I hated Matoko; mainly because she is just a lot more annoying then Matoko. However, the ending made up for that.

(Spoilers)

So Sekai tells Matoko that she's pregnant with his baby and the entire school; Kotonoha, finds out. However, Matoko makes it clear that he had went back to Kotonoha and tells Sekai to stop being so god-damn clingy. Sekai gets mad and goes to his apartment and kills him with a butcher knife. Scared, she flees the scene and hides out in her room. Kotonoha walks into Matoko's apartment to see him laying dead on the ground and she has yet, another emotional break down.

Sekai then gets a message from 'Matoko' saying that he was on top of the school roof. Naturally, Sekai goes there with the same knife she used to kill Matoko with and ends up meeting Kotonoha. Kotonoha confronts Sekai and shows her Matoko's head which was in a gym bag. Shortly afterwards, Kotonoha takes out her dozuki (Japanese saw) and kills Sekai. From her own insanity she cuts open Sekai and says that Sekai did in fact, lie about being pregnant with Matoko's child.

Basically the last episode, which was my favourite. However, one of the bad game endings was a lot better and more violent.
I'd recrommend this anime to anyone who basically would want their most hated characters to die. :3

yeah it had quiet an ending!

Kotonoha whent NUTS at the end even wors then sekai!

I am so tempted to write a long wall of text on why exactly i hate sekai. >>
