Most of his facial expressions from his posts seem so forced to me. Like he is bored or uninterested in doing them. But obviously he tries to hide it in order to get his audience to send donations or purchase his merch.
I wonder if he is aware he is only known for his looks and because he lacks any discernible talent (doing dances on TikTok and playing high school sports doesn't really count), a sense of humor (never seen him crack a joke, use a pun or be self-deprecating) or an interesting personality (he seems to be a simple normal guy with a routine; not crazy or predictable enough to be entertaining).
That is one downside I see to being beautiful, you get praised and receive better treatment for doing the littlest of anything and it works two ways. One, you become an OCD-type of perfectionist and try to be good at everything (looks, athletics, academics, social skills, talent) to live up to your "perfect" image or two, you become lazy and stay mediocre and coast off your looks (which is about the only thing you work hard to maintain). Grant seems to fall into the 2nd category.
