The resting bitch face is hereditary so yes, I agree with you.
But the possibility of being the his friend's child makes sense, I think the girl in the photo was blond/light haired too? We don't know what happened to him either.
But even if Kido slept with other girls in the past him leaving one who was pregnant doesn't makes sense since he is kind and likes children.
not to sound heartless but maybe the real baby daddy is the unseen one on the left side of the picture and both the mom and son just assumed the more handsome one to be responsible bc damn that child really has no similiarity with Kido not even an ounce of his resting bitch face or whatsover
