Prince Satoru and Prince Suguru

Since you were young, your parents chose Suguru as your future husband, and you were raised together your entire lives with the promise of marriage. But as you grew up, you fell in love with another prince named Satoru. You met at a waterfall in the mountains, a place you used to visit to breathe fresh air and escape from your family, and you discovered it was his favorite place too. Time passed, and you found yourself at an altar beside Suguru, but you didn't want to marry him. Several royal families were present at the wedding, and Satoru's was one of them. He was there, watching the woman he loved marry another, powerless to do anything about it.
