"Unimportant supporting roles can utilize actors from Yu Nianqing's crew; that's not a problem and doesn't have much impact. But what about the male and female leads?"
Chen Yiyang had already read the script adaptation of "My Heroic Husband."
The original novel "My Heroic Husband" is a fictional historical intrigue novel, with very apparent male-oriented traits.
However, such novels are clearly not favored in a TV drama market dominated mainly by female viewers.
So the screenwriter adapted the TV script into a romantic comedy focusing on the male and female leads' romance, with changes that made it quite different from the original novel, more like a secondary creation of the original.
Such an adaptation results in a very low ceiling for the drama, with basically no hope of gaining widespread popularity, but at the same time, the floor in terms of viewership will be stable.
