For some reason, I can't imagine Victor having a father? I don't know why, but for some reason, it just doesn't really "work" for me? Whether it be that he left, died before Victor could remember, or something else. I just can't imagine it.
I hear you. I have a hard time picturing him with a mom as well (except for maybe when he was very young), and that makes me really sad.
On my first viewing of the Grand Prix Final in Episode 1, I actually thought this couple was Victor’s family (because of the dog).
But then on a rewatch, I changed my mind because Makkachin is obviously so much bigger.
But I did find it interesting that you see this couple again at the Grand Prix Final at the very end of Episode 10! (Same lady. Might be the same guy. Lighter hair and no beard.) They put them front and center in the shot again.
Most likely they’re just some reused background figures, but I can pretend, right? :)
