This drama based on the manga has have many adaptions of it, but i still believe that this one is the best, starred the popular actors Koyuki (seen her in "The Last Sauraj" opposite Tom Cruise) and one of my favourite Asian actors Jun Matsumoto- they both give incredible performances as this drama explains the relationship between a human and pet. The Main-hero has to suffer a painful unrequited love as a human pet to his savior and owner, the Main-heroine. It`s really charming and funny, and the main-leads had so much angst going on that i sometimes shed some tears. But the HEA is still sweet to watch!
