Am going to still reading this but I still get this weird feeling when I read this because of the whole thing of her husband is in a frainds with benefits with his knight and she OK with it. ( ̄∇ ̄")
Its is not normal. The prince specially tried hiding it from her and the knight was mortified and begged for forgiveness that literally means it’s morally wrong even in their society. The prince was clearly going behind her back that is cheating.its just because this is fujoshi focused plot the prince van rape her and still fuck on the side with another man and it’ll still be considered the best thing since sliced bread.
God I love this manga ε=ε=(ノ≧∇≦)ノ
