Well in the latest chapters... A major plot point would be eruhaben's age. He's a very very ancient dragon, thus he's coughing up blood. But he eventually decides to extend his life, more like, Cale forced him, and while he was reluctant at first, he finally admitted that being together with his newfound family is something he wants to experience for as long as possible. Also, now... While Cale still talks respectfully to Eruhaben, there was a chapter where Cale was screaming at him (for a valid reason, because of an emergency) and Goldie Gramps was so surprised that he stuttered when he replied to Cale. It was just so cute because Eruhaben almost never stutters.
I'm following the current updates of the novel, so reading this first meeting with Eruhaben is making me emotional uri Goldie Gramps haaah those were the days~
