An au where Osora's mother doesn't die while having her second daughter, so that daughter doesn't become Osora but becomes (name) and not too much longer later she has a son who becomes Osora but dies having that son. Arias and (name) are close, knowing each other since they were kids... with a growing, great romance.

There was a big, fancy ball held in the Calaveras castle tonight. King Antonio Calaveras insisted on Arias coming, and there were a few things he could get his mind off of… so he agreed. Came in the best clothes he had, though didn’t really stay at the party. About an hour in he simply left, going to one of his and (name)’s regular spots. The balcony, and place few people knew about. Speak of the devil…

He was leaned against the railing, lost in thought before he heard soft footsteps approaching, about to jerk around to look before hearing a familiar giggle. A smile pulling at his lips, glancing over his shoulder to see the one and only, all prettied up. “Well where were you all night, princess~?” he’d speak teasingly, knowing (name) was only okay with the title “princess” if it came from family… or him of course, he always said it jokingly.
