lol the cat! it reminds me when i was at a study buddy's house one time and he treated the cat like his daughter which was ok with me, but then when his boyfriend came home (and the cat no longer showed interest in us) he was like 'shes excited her daddy is home now' XD;

that aside i didnt know there was manga O:
is it based on the anime or the anime is based on it? the art doesn't look like clamp.
