A cute little dragon that would have the same age as me, and will never leave my side until the end of the world (or maybe my death :P) And he'd have strong firebreath and flight (like flying rly fast and high)
I'd 爱情 to have a leopard but, even if I was super rich and could afford one, I wouldn't get one since it's not a pet and it might eat me once it's grown.
