Lucien is overjoyed to hear Mira's words. Of course, all his wives trust him, but there's a difference between having the approval of young girls and a woman with thousands of years of experience.
Mira's faith makes Lucien certain that he is on the right path, not just as a man who protects his family but as a King who can lead different races.
"I am so glad you're by my side." He continues to caress and kiss Mira as they fly through Crystal City.
She smiles and kisses him back. "Being by your side makes me happy."
Lucien truly enjoys such moments with his wives. Even though brief, moments like this make him feel that everything is alright, that the many problems surrounding them cannot prevent him from making his beloved ones happy.
So he savors it to the fullest with Mira as they make their way to the city center. Everything is beautiful in that place, streets and buildings made of magical crystals, the water alive, shaping the city itself.
