After firmly making sure that it wouldn't become a problem later, Kaynes blurted out what he was really thinking, which escalated into a massive uproar!! With Kaynes's fiancée, Sylphista, joining in, the sparks spread not only to the prince's former fiancée Henrietta and his partner of true love Lilin, but also to all the nobles and lords across the country, developing into a massive crisis that shakes the very nation...!?
