Amnesia anime

This anime is the most confusing anime I have ever watched. I don't like it, it's frustrating to watch but the only think I like is their tricolor eyes, they're awesome, wish they had contact like that. Also the girl is f-ing stupid. Why the hell would she keep her amnesia a secret?
UPDATE 1/29/13: Okay ep 4 is out. And I officially decided this anime is not worth watching. I was hoping that the plot would get better and reveal more info it's just getting lamer, would Aug 1st keep repeating and with each repeat of the reality she is "dating" the four guys?

The heroine struggles to regain her memories under the guidance of Orion. She then gets a phone call, but she does not recognize the name on her mobile phone screen. She meets her apparent "boyfriend," despite not knowing his face.
