I didn't realize this was cancelled before I started reading from seeing the END tag.
If it was going to get axed anyway I wish they had focused more on the main couple's relationship and their kids and not included the childhood friend who is destined to lose given the premise. Also was hoping they would explain what the deal is with the spell he chants for speed and what the mouse meant by loved(blessed?) by the wind. I'm guessing if this had kept going we'd have some conflict with the dragon king since she dislikes lower lifeforms.
Overall a waste of a good premise
The thing to note is that this was based on a web novel.
And frankly, it isn't a surprise that it was canceled.
Like, was it ever mentioned to the girl WHY he'd have a hard time accepting them as his kids???
Don't worry, this virgin has to be a husband and dad to people he barely met....
And then they added other people way too soon before even making us like the couple and enjoy the relationship....
Is it really a shock???
I mean, the potential is there...
But they should have cleared some of the early problems first, and never added an alternative love interest or female childhood friend... and they should have given breathing room for the relationship...
