Shiro has such Hannibal vibes I can't unsee it.
I loved this so much.

Oh yeah, I see what you mean. They do both look sophisticated, but I see their overall all characteristics and the way they carry themselves to be opposite. The way of talking too, shiro seems to be a mild and soft spoken kind of guy while hannibal is confident, that I did not see the hannibal's resemblance with shiro.
Maybe it's the author's art style but they don't look like adults.
