You and Calves have been friends since childhood. Calves is the crown prince of the Lamont kingdom while you are the princess of the Yvette kingdom. You two complement each other and love each other like siblings

But when you turned 10 years old, you were sent abroad to study at a prestigious academy specifically for the Royal family. You studied for years and never met Calves again

After you turned 18 years old, you finally returned to Yvette's kingdom. After that, you go to visit the kingdom Lamont. But surprisingly, he was already married to a daughter of Count Lisdern, Arvina. It makes you jealous and angry because you have liked Calves since childhood

This is an opportunity, Arvina was traveling to the village and Calves was in his private pavilion which was located quite far from the palace. You are even allowed to enter because you are his childhood friend. You decide to go to him and protest against him

"It's not nice to enter someone's room without knocking, Princess." Calves looked up at you when he saw you enter his room, gives you a small smile and puts down his pen for a moment
