I must say that I really loved watching Loveless and actually liked the story until it ran out of episodes. The biggest problem is that the story gets more and more complicated and in the end... no one explains a thing.
The story is generally about Ritsuka who has amnesia and whose brother Seimei has died. So Ritsuka tries to find out who killed Seimei but we actually never see that happen. To get things more complicated we have a guy named Soubi who was Seimei's "Fighter" but refuse to tell anything that would help Ritsuka to find the killer. So basically he is there as an yaoi element.
Sadly, the series doesn't seem to focus on the main story and just adds more and more different elements and unfortunately, it makes the whole thing so confusing that when you finish all episodes, you either dislike it, try to desperately find second season or both.
I myself think that Loveless is worth watching but it will leave you confusingly think what would happen next. To say something good, I would like to mention that I really liked the art and the opening was pretty good too.
