He doesn't like Gladys, the only reason why they didn't revealed the truth is to protect the royal family reputation, that's why they used Erna as shield from the public bad opinion.
It's horrible because she's the purest one.... she's the other end of what they claim her to be... Σ( ￣□￣||)
They were married only for political purposes.He didn't love her but he did treat her well.He didn't reveal the truth cause his country got many benefits(like trading, mining rights etc)for maintaining Gladys's reputation.She is Lars's beloved princess after all.
I'm on chapter 76 but I don't understand something?? Was he in love with Gladys it said it earlier than he didn't love her. But then why does he not reveal the truth? Why is it that he plays the bad guy for her sake when she was the one who she claims erna is? The irony is annoying.
