I've been binging The Apothecary's Diaries lately and I've become absolutely obsessed (I haven't caught up yet though so please no spoilers!)
For those who don't know it, the story is about Maomao, an apothecary apprentice who is kidnapped and sold to the imperial court as a worker, specifically to work for the emperor's concubines.
There's one episode early on (like ep. 3 or 4) where - with as few spoilers as possible - the emperor's least favorite concubine is gifted to a newly appointed general. This turns out to be a ploy between the concubine and the general who are childhood friends
But... what if it hadn't been a ploy
I've been turning this plotline over and over in my head, an Apothecary's Diaries AU with Jing Yuan as the general, a brilliant strategist and childhood friend of the emperor. He's never taken a wife (I don't think I could make this reader truly gn) for whatever reason, the emperor is growing concerned and gets the brilliant idea about throwing his least favorite concubine (ie. Reader who, I'unno, sneezed in the emperor's presence and was instantly demoted to least favorite) at Jing Yuan.
And of course Jing Yuan falls head over heels in love instantly.
Not sure if I'd ever get around to writing this, writing hasn't been at all easy lately, but... it's a nice idea.
