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.

The Calaveras family (Osora, Celia, Antonio, and [name])… including Arias because of his hard work recently, went to a private beach area. Why? Money. Why stay cooped up in a castle when you can pay… whoever to get a private spot on the beach for you? So that was that, they went to have a relaxing day.

Arias would pull off his loose shirt, rolling his eyes as Celia made some flirty comment about his muscular chest and/or general body, looking over at Osora and Antonio who were talking, then… over at a gorgeous little someone… (name) and their beautiful self. He’d smile/smirk, throwing his shirt on the nearest chair and walking over to them, saying as he crossed his arms over his (large, muscular, bare) chest, “And are you gonna be relaxing or working ~?”
