Chuujitsu na Lewis

Lewis has served Prince Edward since he was a child.
His loyalty and love for Edward have just grown since then, but he has never shared his feelings given their difference in status. No matter how much the heat of Edward's eyes burned him.
One day, however, he is summoned at night to the prince’s room and is told that he has to marry a princess from another country.
He gave his loyalty, love, and everything else to him, and all he wanted was to be by his side. But that's not what happened...
