Whatever Alexander will do to bring the Etona kingdom under his control, even if he has to cooperate with the devil.
He's been an asshole all along. He slept with many women he didn't love and followed his lust. He even got stuck with an old witch-like Widuna because of her beauty but it was different from what he felt for Airin.
Airin made him forget that he was a jerk who liked to force his will but he was so afraid of making Airin hurt if he forced her but Airin still wouldn't accept him.
Maybe because he had killed her before, but to hell with Airin and the feelings in his heart now because he also couldn't resist the very seductive Widuna.
Widuna is the best, to be honest, he also misses Widuna's body and the pleasure she gives, and who would have thought that he was so lucky because the conditions that Widuna gave him to make up with her were very pleasant.
