Indeed, what a good match of broken pieces.
The brother is heartless and the princess, "worthless".
They will have to learn from each others to complete themselves as "human".
Spoiler :
Just Kidding! They gonna end up as scumbags until Princess, aka, the Empress, finally lives true love story with the knight.

To the so-called parents :
You want me for my money? Fine.
But don't forget to shush that big mouth of yours in front of me.
For Li Lei:
This boi's love deserves more respect and recognition. I understand she is leaving with PTSD, but please, learn "EMPATHY" in your new life.
Someone is not lucky when it comes to handling men.
My! I can understand the charm of such strong and resplendent lady.

She does not look like the type to "commit crimes" and is quite pet-friendly (cat). She suffers from so many deaths, felt that pain so much, values human life to a new extent, seeks justice for those who died.
And she, without hesitation, did that to the dog? Well, it was the dog or the servant. NO, it was not. It was the servant or something else. She is getting tough in the wrong way. ( ̄∇ ̄")

Is everyone, expect the main characters, out of their mind? No, I need to phrase it better. Wouldn't mind the author to give the foolish folk a bit of common sense?
The so-scary and threatening Lewis gave them more than three peremptory warnings about "stopping talking low" about his lady and they still continue badmouthing her for more than 10 chapters and go "Oh! I am so scared! I don't want to die!"
Are you scared or not? As someone who studied psychology and behaviors, this is quite appalling when it happens for WAY TOO MUCH chapters in a row.
And what is Lewis waiting to sentence to death half of those fools? Since it is Ancient China-ish, history would suggest that more blood would have dropped to clear such disgrace (NO, period does not count).
Dealing with a Tsundere Father is not easy.
