Maybe 1-3 chapters more (based on novel)
The blood is about superiority of one royal whose born rarely or with great talents, but the consequence is the royal is so superior that he has this "boredom" that has to be quenched. In the game version the prince got over his boredom through his obsession to wars but as Tia in this story is so interesting, his obsession directs to her instead.

or this is spoiler? this is a little different with the novel or maybe they'll put it in the end? oh well, the novel has long explanation. I'll try to minimized the spoiler (if any)

Tsundere.
He's saying it off, but reading his interview it's a good thing. And about work, it's normal being strict with it. Chowon said it himself that he already warned him couple of times.
Then about their relationship, I think Chowon just wants more quality time with themselves. Like he wants him to work closely to him so they can be together always.
Just my take on this.
There are ways to tell his partner « I want to spend more time with you ». Also, he has no right to boss Kyungsoo around like he’s one of his employees or works for him. He shouldn’t demand things the way he does as if Kyungsoo owes him something. The way Chowon speak to him is not right either.
He's learning. He's on the way there
It's hard for a person to change overnight.
It's a process.
