This story is basically just like the Kdrama "Meow, Secret Boy" Both male leads are in it, and L plays the cat in that one, and so its basically the same thing so I would just watch that one you can find it on Viki and dramacool
I just finished it last night around 2:47am, and im glade that I did even tho it made me cry tears of happinees, now yes I has happy when he reveled himself, but I hated some of the second lead male characters, the thing that I loved the most was that this show basically tells u that you can love who u wanna love, even if its some smart AI. <3
