Qi Rong, his heart is in a good place but not the best father out there for Gu Zi.
This is about Qi Rong's relationship with Gu Zi. Near the end of the novel, he declares Gu Zi is his son and sacrifices himself for the child. I think it's sweet and all... but I still would rather Gu Zi be with someone else than Qi Rong and his biological father.
Why? The reason is I don't want my son to learn how to devore a human.
