Damn, we live in sad times when even starting a conjecture with "Feels like", people feel forced to further explain that it's not a spoiler, but a guess...
Regarding your point, I don't feel like that... or better, I hope it won't be like that.
I think that the selfish knight might die or cause some deaths due to his incompetence, then his daughter will have to take the reigns and try to stir the troops in a better, more humane direction.
And she will probably need the help of the MC a few times.
From the introduction we've got, she actually seems rather important to the story.
Also, the manga has Harem and Romance tags, but no Drama tags.
