Romance Options You Wanted, but the Game just said No?

I decided to finally give Stardew Valley a try (I was waiting for the latest Switch Update and dealing with a Splatoon 3 addiction, hate those Catalogs) and everything's been going ok so far, until I realized that Marnie, the one character I wanted to marry isn't one of the available Bachelorettes.

Have you ever played a game with Romance Options, only to get heartbroken Best Girl/Boy isn't available?

(You know, outside of Mods.)
