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.

Last night, as usual, Arias went over to (name)’s room… but ended up falling asleep. In the same bed… and what could he do? (Name) cuddled up to him, and why bother getting that lil’ cutie off? (name) woke up around the same time they usually did, only to immediately see, feel, and smell Arias. He was still out cold… Why let this one of a kind moment slip~?
