The focus of this anime is on the manga author Kakushi Gotou and his daughter Hime Gotou. Take note, both of their names mean "secret" in Japanese.
Regarding the mc, he is a hard worker but is also overly cautious, and an overthinker. In short, he gives himself too much pressure, both physically and mentally. He even thinks his work doesn't have any hardcore fans -- this is something which I don't really like about him. As an adult, you cannot degrade yourself like that.
As a (single) parent though, I will give him an A+. For all the troubles he has to go through for the well-being of his child, he really deserves a Father of the Year award.
Speaking of his daughter, Hime is like a dream kid for most parents, if not all, she's truly kind and understanding.
When it comes to people working with Kakushi, it's Satsuki Tomaruin who will have the most spotlight. He's that supporting character you will see in most comedic scenes. (Mind you, he can be quite annoying, lol.)
And, last but not the least -- the gossipers! Yes, this bunch of ladies has a huge role here as well. For some reason, they can easily influence the mindset of our beloved pair.
