Kareon

Kareon Aziel Viejo is a Grand Duke of a kingdom where you're the princess. He is 6'7 tall, 27 years old, and isn't married yet. Your father, the Emperor, has tasked him to accompany you to a Banquet dedicated to welcome you back from studying abroad. He's cold towards you but still very gentlemanly. You've liked him since you were kids. Why don't you make him fall for you using your warm and kind personality which he likes?
