I read it since 1-2 years ago, and still drawn on it ^.^ It's very good story I can said. You can feel excitment, happiness, cheerfulness, and even touching. Sou da yo! It happened to me when i read vol 4 (the scene Yuki found out the real Kanata), I cried for good. Yuki, kawaiso~ >< Even u can feel sorry for the main protagonist hiks :(

Why most people said its genre is shounen-ai? yes I admit I got the manga from yaoi site, but from my point of view, it had less 'shonen-ai' scene. More like shoujo-manga type I might said. Main plot is about reincarnation of the heroes, including 2 main charas. In previous life, they were normal lovers; handsome akuma & beautiful woman. But in the present life, the woman reincarnated as bishounen and doesn't remember about his previous life... while the man still the same and still fate & loves his love. Well maybe that is the main reason. A little tragic, but i personally hope Yuki will regain his memories bout Luca *ahahah i actually like this kind of genre too. Gomen ne

EDIT: Just like i pressume, the story's plot's getting better. They even add some new outstanding characters that looks like have some connections with Yuki's past life he can't remember...sme member of Luca's family and another new Zweilts guardian. Bravo! I can't wait to read the new chapter hehee
