Ro said in the beginning (1st chapter) that he's a Mountain dog, aka a wolf, aka a Japanese wolf (based on the author's note), so then, his previous family has been keeping... a wolf.. a wild animal as a pet ??
no he was not, he was a puppy, but had always been a regular black dog. He grew bigger as he lived there. if check all the scenes he appears in when living with his first family he looks like a medium/big size dog
Nami is so precious.. it hurts knowing that she'll be the one getting hurt, and she had wasted all those 10 years for a guy who will end up with another guy. Where will she end up then..
Mommy knows what's goin' on~
(Not rly his mother tho) but because she cares like that
