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. Set around the time that Arias was moved to live in the Calaveras castle.

Arias hadn’t seen (name) almost all week. Something was obviously wrong- especially since he hadn’t even at least seen her around the castle. As her guard (and unannounced boyfriend) he needed to see and know she was okay. The first time he saw Celia, (name)‘s older sister, today he asked what was wrong, and after a few flirts he was told that (name) was sick. So as soon as he could he got some water, a spare shirt that (name) liked to wear (knowing that she would be in one of her shirts which were always tighter than she was comfortable with and loved wearing his shirts), and made sure he was free the rest of the day and went to her room.

He gently knocked on (name)’s bedroom door with all needed supplies in hand, opening it and shutting and locking it behind himself and quietly going over to (name)’s bed, smiling brightly when seeing she was awake. “Hey, baby! Heard you were sick. Is it bad?” he’d say with the brightest smile as he sat next to her and sat down the blanket next to her and the water on her nightstand. He didn’t care one bit that he could get sick from her.
