Last year I wrote my first full chaptered minwon fic about real (canon) Wonwoo discovering the omegaverse through a fanfic about him and Mingyu. You don't have to read it but I'll share - https://archiveofourown.org/works/63564757/chapters/162900559

Anyway, it's a story within a story and Omega Wonwoo is rich and Alpha Mingyu is poor, and they can only smell each other's pheromones. I love that concept of being tied to each other biologically!

Another trope I just love from BL or manhwa in general where the couple knows each other from a young age, and everyone assumes the top would be an omega bc of appearance, but grows up to be a very dominant alpha.
