Spoilers
You think she knows about his past? All she knows is that Blanche wasn't getting the attention she needs for a child and went to make an effort to fix their relationship. In the eyes of the mc, she thinks the king was distraught of the death of his 1st wife but in truth, he's traumatized. He was taken WITHOUT HIS CONSENT when he had a cold which made Blanche, lets also take into account HIS OWN MOTHER consented his 1st wife to do it making matters worst.
Men can be victims too people. Don't blame Mc for not knowing what happened to him, it was elaborated several times that he keeps to himself so of course no one knows what happened. The mirror boy knows a bit because he is the definition of "the hall has eyes" although he can't confirm himself that happened because he only heard of them as mere baseless rumors.
