Why does the mc and the creepy old man look alike

(⊙…⊙ )

well maybe because they're drawn by the same artist?

I meant could he be hinted to be his father or something , they’re too similar to be juts art style
I’m just saying maybe the author didn’t just draw them similar for nothing

but his dad passed in a fire i don't thinks it means anything, I mean even he and ml in the first chapter were looking the same
