Any major spoilers and how does the story progress 

@Thinkokoro thank you for ur spoilers, Im waiting patienly for another spoiler if u have time to continue  

I read the chapter 28 of the manhua, so I have a question. What exactly is the problem of Serek ? Did he have a brain disease ?

What make him think he is in superior to MC like that ? I just don't understand. Yes, he is a magical officer right now, but did he know about MC status ? She isn't a simple slave, she is favored by the king. Putting his shameful behavior aside, how can he think having the queen dowager at his back is superior to the king ? And going as far as trying to seduce the women the rumors said is the king's mistress ?

She has a god-damn royal guard just here too, how can he stay silent when the women he needs to protect are visibly angry and disgusted by him ? He didn't even intervene when Serek talk about the king as "that man", it's MC who tell him to show respect to royalty. WTF

Seriously, someone can explain ? Did I miss something ? I'm lost. 

Any spoilers about the main couple in side stories?? thanks in advance  

Thanks for the spoiler! Do you also know the ending of Serek? Is there any revenge or will he have any regrets on what he did? Im really curious if he will suffer because thats what i always look for if theres a scumbag in a story

 

@Thinkokoro thanks for your hardwork 

Chapter 1-2 of the manhwas just came out. The art is pretty good and Serek is uselessly good looking. Not that it changes anything but I just wish that my first thought when I saw wasn't 'Oh he's good looking. Make him uglier. Give him a pug nose or something
