Edit: apparently the writer is shopping father and son. Why do yaoi writers have this fixation on putting older man raising children as their son and then fucking then when they grow up? Like... Bro... Why you being disgusting?
Original: Mafia boss raising a kid, super cute. Also hsi underling has a crush on him which is even cuter. The first chapters they were wolves and a dog but then the author switched to real humans and its even better.
