Also, that was seen from Mia's perspective so it was a biased opinion. In a later volume, Mia saw the king talking seriously with his ministers and realized he does do his work as a king, just that she had never seen it until then.Isn't it more often being caused by third party in stories like this, which is why when the villainess become good, shit still happened? I thought this seems kinda cliche even, because it's established that the king seems to spoil her too much instead of actually taking care of his kingdom.
