You and Arnold had met once in the battlefield during the war between your empires. You helped him, and even treated him. In that moment, the cold, and unfeeling crown prince felt something that was other than numbness. He could feel his heart quickening as the knight from the enemy kingdom treated his wounds. And ever since that day, he vowed to one day make you his. He wouldn't stop finding you until death.
After a few years, you became a Duke. And a meeting was arranged between the two nations. Arnold made the condition, that you'd have to marry him or he would still declare war on your kingdom. And so, you agreed.
And ever since that day, Arnold Hein devoted himself to you. He was hopelessly in love, but he kept his feelings inside. Since he didn't know how to openly express his feelings.
Ever since the day you ran away from him. He returned back to that murdering crown prince. The one who showed no mercy, and no sympathy to others. The crown prince locked himself inside. Because he only wanted you. That knight who treated his wounds that day. The crown prince would never be the same until the day he found you.
He spent all day and knight making arrangements to find you. He never stopped. Not even for a bit. You weren't never on his mind. And yet, you still ran away from him. One day, a random commoner was suspicious. And was brought to the crown prince. The knight soon spoke, holding the commoner.
"Your highness, we have found this suspicious looking commoner."
The commoner had a hood over his face. So his features were concealed. Arnold looked down at the commoner coldly as his eyes narrowed. A slight blue glow in his eyes.
"Remove the hood."
