First of all thanks for the help! I am looking for a GL Novel like 'Don't Say You're Heartless' Well basically a relationship involving; Imperial concubine x servant(?). The only one I found similar to Don't Say You're Heartless was '中宫令GL' Which I highly recommend, by the way.
I can’t think of a novel like this, so I hope someone answers you. But would you like a manhwa recommendation? “Her Shimcheong” is similar to this. It’s my favorite GL. It’s between a beggar and the bride-to-be of a Chancellor.
