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 is (name)’s guard… with loads of romance. Arias was looking around the castle for (name) when he saw Osora, their and Celia’s younger brother, asking him where they were, and… Osora said they were in the dining room, that the king (Antonio) hosted a dinner to celebrate… something with a big company, some of those people coming to the dinner.

When he got there, he saw Antonio, Celia, (name), a few other people, and some old dude close to (name) and Antonio. He couldn’t see (name)’s face, but Celia looked upset- uncomfortable, disgusted even. As he got closer he heard the conversation… ”…I am looking for a wife. It would benefit my company and the kingdom, y’know ~?” the old dude would say, Antonio responding, ”Of course. There aren’t any princes near our kingdom, so maybe when (name) turns 18, you-” Arias had the worst feeling in his stomach. He came over to and wrapped his arm around (name)‘s waist/shoulders, easily towering over everyone around besides Antonio, Celia’s disgusted look brightening.
