Guess so. Yeah i definitely thought they died. (even cried for it)
Then if this is following the story of the dog, I think there is a chance that his mother (human) will die too. Then Kiddo is left where Boss found him in order to protect him. Maybe?
I think if it follows the dog version, then his mom and sibling died in an accident on the mountain, which left the kid alone. But, the blonde woman could be a relative based on the hair but also an influential mafia lady based on how respectful the subordinates are.
OMG I JUST CANT!!
Who is that woman? Maybe the mother of the puppy? In contrast, in a dog form, his mother died right?
Btw, Boss smiling at his puppy's photos is so cute~
