@Anonymous manwha reader no wtf... he's a grown man and pup is a child who's a 7 year-old. and the "grown" version is them years after the original story so the age thing doesn't change. even if pup was an adult that still counts as incest because he's wolfs adopted son. HE'S HIS SON. and they definitely have an age difference around 20 years. go get a life and a therapist.
dunno what I'm doing
