From my understanding, he has anti-social behavior disorder, which causes him to act out and do weird ass shit like this. It also stems from how he grew up.. basically he has a major lack of proper social skills
Yeah. He isn't normal. It's because he is a dominant alpha as well as he is from the Miller bloodline.
in this universe dominant alphas are not normal. They can only feel love/empathy with their mated one.
Mini spoiler
that's why his dad took him and his brothers away from Koi to teach them how to be "normal". So all emotions/feelings Grayson have are not natural.
If am not wrong in this world dominant alpha pheromones are kinnda toxic to the brain so yeah he is (there is more to it but is more of a spoiler for the other brothers and fathers )
Kinda, he has alexithymia.
Is greyson someone with special condition. . . Like he doesn't act like normal people . . . Like something weird in his logic . . .
